Cache
To enable faster data access from disk storage, the following two types of caching are performed:
• Posted-write caching. The controller writes user data in the cache memory on the module rather than
directly to the drives. Later, when the storage system is idle, the controller writes the data to the drive
array.
• Read-ahead caching. The controller detects sequential array access, reads ahead into the next
sequence of data, and stores the data in the read-ahead cache. Then, if the next read access is for
cached data, the controller immediately loads the data into the system memory, avoiding the latency of
a disk access.
Transportable CompactFlash
During a power loss or array controller failure, data stored in cache is saved off to non-volatile memory
(CompactFlash). This data is then written to disk after the issue is corrected. To protect against writing
incomplete data to disk, the image stored on the CompactFlash is verified before committing to disk.
In single-controller configurations, if the controller has failed or does not start, and the Cache Status LED is
on or blinking, the CompactFlash will need to be transported to a replacement controller to recover data
not flushed to disk. (See Controller failure in a single-controller configuration for more information.)
CompactFlash

Download from Www.Somanuals.com. All Manuals Search And Download.
CAUTION: To preserve the existing data stored in the CompactFlash, you must transport the
CompactfFash from the failed controller to the replacement controller using a procedure outlined in the HP
StorageWorks 2312fc/2324fc controller replacement instructions, shipped with the replacement controller.
Failure to use this procedure will result in the loss of data stored in the cache module. The CompactFlash
must stay with the same enclosure. If the CompactFlash is used/installed in a different enclosure, data
loss/data corruption will occur.
IMPORTANT: In dual controller configurations, there is no need to transport a failed controller’s cache to
a replacement controller because the cache is duplicated between the controllers.
Super-capacitor pack
To protect RAID controller cache in case of power failure, the MSA2324fc is equipped with super-capacitor
technology. The super-capacitor pack and CompactFlash memory in each controller module provide
unlimited cache memory backup time. The super-capacitor pack provides energy for backing up unwritten
data in the write cache to the CompactFlash in the event of a power failure. Unwritten data in
CompactFlash memory is automatically committed to disk media when power is restored. While the cache
is being maintained by the super-capacitor, the Cache Status LED flashes at a rate of 1/10 second on and
9/10 second off.

Connecting controller and MSA2000 3.5 12-drive enclosures
You can connect up to three MSA2000 3.5 12-drive enclosures to an MSA2324fc. The cabling diagrams
shown in this section show the recommended fault-tolerant cabling patterns.
IMPORTANT: Connecting an MSA2000 3.5 12-drive enclosure to an MSA2324fc requires mini SAS to
SAS cables. Check the QuickSpecs for an updated list of supported cables. QuickSpecs can be found from
your product. The link for QuickSpecs is on the right.
IMPORTANT: The MSA2324fc can also be attached to an MSA70 that is running firmware version 2.18 or
later. For information about the MSA70, see the HP StorageWorks 70 Modular Smart Array Enclosure user
guide located on the MSA2000 Software Support/Documentation CD shipped with your product or at
When connecting multiple drive enclosures, use reverse cabling to ensure the highest level of fault
tolerance. Controllers and I/O (expansion) modules are identified by
module 2A, and the chain of connections continuing down. Controller 1B is connected to the lower
module (B) of the last drive enclosure in the chain, with connections moving in the opposite direction.
NOTE: For clarity, the schematic illustrations of the controllers shown in this section show only relevant

Testing enclosure connections
1. Press the power switches at the back of each drive enclosure to On.
IMPORTANT: This ensures that the disks in the enclosures have enough time to completely spin up before
being scanned by the RAID modules in the controller enclosure.
While enclosures power up, their LEDs blink. After the LEDs stop blinking, if no LEDs on the front and
back of the enclosure are amber, the power-on sequence is complete and no faults have been detected.
2. Press the power switches at the back of the controller enclosure to On.
Depending on the number and type of drives in the system, it can take several minutes for the system to
power up.
Obtaining IP values
NOTE: For help with configuring your MSA2000 product, also see the MSA2000 Software
Support/Documentation CD shipped with your product.
Setting management port IP addresses using DHCP
1. Look in the DHCP server’s pool of leased addresses for two IP addresses assigned to “HP
StorageWorks MSA Storage.”
2. Use a network management utility to discover “HP StorageWorks MSA2300fc” storage devices on the
local LAN through SNMP.
3. Use a pingbroadcast to try to identify the device through the host’s ARP table.
If you do not have a DHCP server, you will need to ask your system administrator to allocate two IP
addresses and set them using the CLI during initial configuration (see Setting management port IP
Setting management port IP addresses using the CLI
NOTE: If you used DHCP to set the IP addresses, you do not have to set them using the CLI as described
in this section.
Ethernet Management ports on controller module A and controller module B are configured with the
following default values:
• Management Port IP Address: 10.0.0.2 (controller A), 10.0.0.3 (controller B)
• IP Subnet Mask: 255.255.255.0
• Gateway IP Address: 10.0.0.1
If the default IP addresses are not compatible with your network, you must set an IP address for each
management port using the command-line interface (CLI) embedded in each controller module. The CLI
enables you to access the system using RS-232 communication and terminal emulation software.
Use the CLI commands described in the steps below to set the IP address for the Ethernet management port
on each controller module.
Once new IP addresses are set, you can change them as needed using SMU.
NOTE: Changing IP settings can cause management hosts to lose access to the storage system.

1. From your network administrator obtain an IP address, subnet mask, and gateway address for
controller A and controller B.
2. Use the provided micro-DB9 serial cable to connect controller A to a serial port on a host computer.
Your package contents include a micro-DB9-to-DB9 serial cable. If necessary, use a DB9-to-DB25 adapter
(not included) for connecting the serial cable to a DB25 serial port on the host computer.

6. At the prompt, type the following command to set the values you obtained in Step 1 for each Ethernet
management port, first for controller A and then for controller B:
set network-parameters ip address netmask netmask gateway gateway controller a|b
where:
• address is the IP address of the controller
• netmask is the subnet mask
• gateway is the IP address of the subnet router
• a|bspecifies the controller whose network parameters you are setting
For example:
# set network-parameters ip 192.168.0.10 netmask 255.255.255.0 gateway
192.168.0.1 controller a
# set network-parameters ip 192.168.0.11 netmask 255.255.255.0 gateway
193.168.0.1 controller b
7. Type the following command to verify the new IP addresses:
show network-parameters
Network parameters, including the IP address, subnet mask, and gateway address are displayed for
each controller.
a. From the CLI you can use the PING command to verify network connectivity
For example:
# ping 16.125.12.1
Info: Pinging 16.125.12.1 with 4 packets.
Success: Command completed successfully. The remote computer responded with 4 packets.
8. Disconnect from the CLI and exit the emulator.
9. In the host computer's command window, type the following command to verify Ethernet connectivity,
first for controller A and then for controller B:
ping IP-address
If you cannot your access your system for at least three minutes after changing the IP
address, your network might require you to restart the management controller using the serial CLI. When
you restart a management controller, communication with it is temporarily lost until it successfully restarts.
Type the following command to restart the management controller on both controllers:
restart mc both

4 Connecting hosts
Host system requirements
Data hosts connected to MSA2324fc arrays must meet the following requirements:
• Depending on your system configuration, data host operating systems may require that multipathing is
supported.
If fault tolerance is required, then multipathing software may be required. Host-based multipath
software should be used in any configuration where two logical paths between the host and any
storage volume may exist at the same time. This would include most configurations where there are

5 Basic operation
Powering on/powering off
Before powering on the enclosure for the first time:
• Install all hard drives in the enclosure so that the connected host controller can identify and configure
them at power-up.
• Connect the cables and power cords to the enclosure as explained in the Installation Poster.
• Generally when powering up, make sure to power up the enclosures and associated data host in the
following order:
• Drive enclosures first
• Controller enclosure next
• Data hosts last (if they are powered down for maintenance purposes)
To power on the system:
1. Press the power switches at the back of each drive enclosure to the On position.
2. Press the power switches at the back of the controller enclosure to the On position.
To power off the system:
1. Stop all I/O from hosts to the system.
2. Use SMU to shut down both controllers. See the SMU online help or CLI reference guide for information
on shutting down controller.s
Wait until SMU indicates that processing is complete.
3. Press the power switches at the back of the controller enclosure to the Off position.
4. Press the power switches at the back of each drive enclosure to the Off position.
Updating firmware
After installing the hardware and powering up the enclosure for the first time, be sure to verify that the
controllers and drive enclosures have the latest firmware. SMU enables you to view the software, hardware,
and other version information for each controller and the enclosures.
To view controller version information, in the Configuration View panel, right-click the system, select View >
Overview, and select the Versions button in the System Overview Table. To view drive enclosure
information, in the Configuration View panel, right-click the enclosure and select View > Overview. The
enclosure firmware is listed as EMP A Revision and EMP B Revision.
For software and firmware updates, including language packages and firmware update instructions, go to
http://www.hp.com/go/msa. Select MSA SAN Arrays, select your product, and go to Support.
Selecting an appropriate time to perform the online upgrade
To ensure the success of an online upgrade, selecting the appropriate time is essential. Selecting a period
of low I/O activity will ensure the upgrade completes as quickly as possible, and will avoid disruptions to
host and applications due to timeouts. Attempting to upgrade a storage system that is in the middle of
processing a large I/O intensive batch job will likely cause hosts to lose connectivity with the storage
system. Consequently, finding an appropriate time for the upgrade is very important.

If the LED is blinking evenly, a cache flush is in progress. When a
controller module loses power and write cache is dirty (contains
data that has not been written to disk), the super-capacitor pack
provides backup power to flush (copy) data from write cache to
Compact Flash memory. When cache flush is complete, the cache
transitions into self-refresh mode.
If the LED is blinking momentarily slowly, the cache is in a
self-refresh mode. In self-refresh mode, if primary power is restored
before the backup power is depleted (3–30 minutes, depending on
various factors), the system boots, finds data preserved in cache,
and writes it to disk. This means the system can be operational
within 30 seconds, and before the typical host I/O timeout of 60
seconds at which point system failure would cause host-application
failure. If primary power is restored after the backup power is
depleted, the system boots and restores data to cache from
Compact Flash, which can take about 90 seconds.
The cache flush and self-refresh mechanism is an important data
protection feature; essentially four copies of user data are
preserved: one in each controller’s cache and one in each
controller’s CompactFlash.

Changing the system date and time
You can change the storage system's date and time, which are displayed in the System Status panel. It is
important to set the date and time so that entries in system logs and event-notification email messages have
correct time stamps.
You can set the date and time manually or configure the system to use Network Time Protocol (NTP) to
obtain them from a network-attached server. When NTP is enabled, and if an NTP server is available, the
system time and date can be obtained from the NTP server. This allows multiple storage devices, hosts, log
files, and so forth to be synchronized. If NTP is enabled but no NTP server is present, the date and time are
maintained as if NTP was not enabled.
NTP server time is provided in Universal Time (UT), which provides several options:
• If you want to synchronize the times and logs between storage devices installed in multiple time zones,
set all the storage devices to use UT.
• If you want to use the local time for a storage device, set its time zone offset.
• If a time server can provide local time rather than UT, configure the storage devices to use that time
server, with no further time adjustment.
To use manual date and time settings
1. In the Configuration View panel, right-click the system and select Configuration > System Settings >
Date, Time. The date and time options appear.
2. Set the options:
• Time. Enter the time in the format hh:mm:ss.
• Month.
• Day.
• Year. Enter the year using four digits.
• NTP. Select Disabled.
3. Click Set Time Values.
To obtain the date and time from an NTP server
1. In the Configuration View panel, right-click the system and select Configuration > System Settings >
Date, Time. The date and time options appear.
2. Set the options:
• NTP. Select Enabled.
• NTP Time Zone Offset. Optional. If the system timestamps should use the NTP server's time zone
instead of the local time zone, enter the time zone offset.
• NTP Server Address. Optional. If the system should retrieve time values from a specific NTP server,
enter the address of an NTP server. If no IP server address is set, the system listens for time messages
sent by an NTP server in broadcast mode.
3. Click Set Time Values.

8 Troubleshooting
Fault isolation methodology
The MSA2000 Family storage system provides many ways to isolate faults within the system. This section
presents the basic methodology used to locate faults and the associated FRUs.
The basic fault isolation steps are:
• Gather fault information, including using system LEDs
• Determine where in the system the fault is occurring
• Review event logs
• If required, isolate the fault to a data path component
Gather fault information
When a fault occurs, it is important to gather as much information as possible. Doing so will help you
determine the correct action needed to remedy the fault.
Begin by reviewing the reported fault. Is the fault related to an internal data path or an external data path?
Is the fault related to a hardware component such as a drive module, controller module, or power supply?
By isolating the fault to one of the components within the storage system, you will be able to determine the
necessary action more rapidly.
Determine where the fault is occurring
Once you have an understanding of the reported fault, review the enclosure LEDs. The enclosure LEDs are
designed to alert users of any system faults and might be what alerted the user to a fault in the first place.
When a fault occurs, the Fault ID status LED on an enclosure’s right ear (see Front panel components)
illuminates. Check the LEDs on the back of the enclosure to narrow the fault to a FRU, connection, or both.
The LEDs also help you identify the location of a FRU reporting a fault.
Use SMU to verify any faults found while viewing the LEDs. SMU is also a good tool to use in determining
where the fault is occurring if the LEDs cannot be viewed due to the location of the system. SMU provides
you with a visual representation of the system and where the fault is occurring. It can also provide more
detailed information about FRUs, data, and faults.
Review the event logs
The event logs record all system events. It is very important to review the logs, not only to identify the fault,
but also to search for events that might have caused the fault to occur. For example, a host could lose
connectivity to a virtual disk if a user changes channel settings without taking the storage resources
assigned to it into consideration. In addition, the type of fault can help you isolate the problem to
hardware or software.
Isolate the fault
Occasionally it might become necessary to isolate a fault. This is particularly true with data paths due to
the number of components the data path consists of. For example, if a host-side data error occurs, it could
be caused by any of the components in the data path: controller module, cable, or data host.
If the enclosure does not initialize
It may take up to two minutes for the enclosures to initialize. If the enclosure does not initialize:
• Perform a rescan.
• Power cycle the system.
• Make sure the power cord is properly connected and check the power source that it is connected to.
• Check the event log for errors.

Download from Www.Somanuals.com. All Manuals Search And Download.
Correcting enclosure IDs
When installing a system with drive enclosures attached, the enclosure IDs might not agree with the
physical cabling order. This is because the controller might have been previously attached to some of the
same enclosures during factory testing and it attempts to preserve the previous enclosure IDs if possible. To
correct this condition, make sure that both controllers are up and perform a rescan using SMU or the CLI.
This will reorder the enclosures, but can take up to two minutes for the enclosure IDs to be corrected.
To perform a rescan using the CLI, type the following command:
rescan
To rescan using SMU:
1. Verify that both controllers are operating normally.
2. In the Configuration View panel, right-click the system and select Tools > Rescan Disk Channels.
3. Click Rescan.

Controller failure in a single-controller configuration
Cache memory is flushed to CompactFlash in the case of a controller failure or power loss. During the write
to CompactFlash process only the components needed to write the cache to the CompactFlash are
powered by the super-capacitor. This process typically takes 60 seconds per 1 Gbyte of cache. After the
cache is copied to CompactFlash, the remaining power left in the super-capacitor is used to refresh the
cache memory. While the cache is being maintained by the super-capacitor, the Cache Status LED flashes
at a rate of 1/10 second off and 9/10 second on.
IMPORTANT: Transportable cache only applies to single-controller configurations. In dual controller
configurations, there is no need to transport a failed controller’s cache to a replacement controller because
the cache is duplicated between the controllers.
If the controller has failed or does not start, is the Cache Status LED on/blinking?
Answer
Actions
No, the Cache LED status is off, and the
controller doesn’t boot.
If valid data is thought to be in Flash, see Transporting
Cache; otherwise, replace the controller.
No, the Cache Status LED is off, and the
controller boots.
The system is flushing data to disks. If the problem
persists, replace the controller.
Yes, at a strobe 1:10 rate - 1 Hz, and the
controller doesn’t boot.
Yes, at a strobe 1:10 rate - 1 Hz, and the
controller boots.
The system is flushing data to disks. If the problem
persists, replace the controller.
Yes, at a blink 1:1 rate - 1 Hz, and the
controller doesn’t boot.
Yes, at a blink 1:1 rate - 1 Hz, and the
controller boots.
The system is flushing data to disks. If the problem
persists, replace the controller.
Transporting Cache
To preserve the existing data stored in the CompactFlash, you must transport the CompactFlash from the
failed controller to a replacement controller using a procedure outlined in the HP StorageWorks
2312fc/2324fc controller replacement instructions, shipped with the replacement controller. Failure to use
this procedure will result in the loss of data stored in the cache module.
CAUTION: Remove the controller only after the copy process is complete, which is indicated by the
Cache Status LED being off.

Resolving voltage and temperature warnings
1. Check that all of the fans are working by making sure each power supply’s DC Voltage/Fan
Fault/Service Required LED is off or by using SMU to check for yellow yield icon hardware warnings.
(In the Configuration View panel, right click the enclosure and click View > Overview.)
2. Make sure that all modules are fully seated in their slots and that their latches are locked.
3. Make sure that no slots are left open for more than two minutes.
If you need to replace a module, leave the old module in place until you have the replacement or use a
blank module to fill the slot. Leaving a slot open negatively affects the airflow and can cause the
enclosure to overheat.
4. Try replacing each power supply one at a time.
5. Replace the controller modules one at a time.

Sensor locations
The storage system monitors conditions at different points within each enclosure to alert you to problems.
Power, cooling fan, temperature, and voltage sensors are located at key points in the enclosure. In each
controller module and expansion module, the enclosure management processor (EMP) monitors the status
of these sensors to perform SCSI enclosure services (SES) functions.
The following sections describe each element and its sensors.
Power supply sensors
Each enclosure has two fully redundant power supplies with load-sharing capabilities. The power supply
sensors described in the following table monitor the voltage, current, temperature, and fans in each power
supply. If the power supply sensors report a voltage that is under or over the threshold, check the input
voltage.
Table 6 Power supply sensors
Description
Event/Fault ID LED condition
Power supply 1
Voltage, current, temperature, or fan

Power supply 2
Votlage, current, temperature, or fan

Cooling fan sensors
Each power supply includes two fans. The normal range for fan speed is 4000 to 6000 RPM. When a
fan’s speed drops below 4000 RPM, the EMP considers it a failure and posts an alarm in the storage
system’s event log. The following table lists the description, location, and alarm condition for each fan. If
the fan speed remains under the 4000 RPM threshold, the internal enclosure temperature may continue to
rise. Replace the power supply reporting the fault.

During a shutdown, the cooling fans do not shut off. This allows the enclosure to continue cooling.
Temperature sensors
Extreme high and low temperatures can cause significant damage if they go unnoticed. Each controller
module has six temperature sensors. Of these, if the CPU or FPGA temperature reaches a shutdown value,
the controller module is automatically shut down. Each power supply has one temperature sensor.
When a temperature fault is reported, it must be remedied as quickly as possible to avoid system damage.
This can be done by warming or cooling the installation location.

B Environmental requirements and specifications
Safety requirements
Install the system in accordance with the local safety codes and regulations at the facility site. Follow all
cautions and instructions marked on the equipment.
Site requirements and guidelines
The following sections provide requirements and guidelines that you must address when preparing your site
for the installation.
When selecting an installation site for the system, choose a location not subject to excessive heat, direct
sunlight, dust, or chemical exposure. These conditions greatly reduce the system’s longevity and might void
your warranty.
Site wiring and AC power requirements
The following are required for all installations using AC power supplies:
• All AC mains and supply conductors to power distribution boxes for the rack-mounted system must be
enclosed in a metal conduit or raceway when specified by local, national, or other applicable
government codes and regulations.
• Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed
on the equipment’s electrical rating label.
• To ensure redundancy, provide two separate power sources for the enclosures. These power sources
must be independent of each other, and each must be controlled by a separate circuit breaker at the
power distribution point.
• The system requires voltages within minimum fluctuation. The customer-supplied facilities’ voltage must
maintain a voltage with not more than 5 percent fluctuation. The customer facilities must also provide
suitable surge protection.
• Site wiring must include an earth ground connection to the AC power source. The supply conductors
and power distribution boxes (or equivalent metal enclosure) must be grounded at both ends.
• Power circuits and associated circuit breakers must provide sufficient power and overload protection. To
prevent possible damage to the AC power distribution boxes and other components in the rack, use an
external, independent power source that is isolated from large switching loads (such as air conditioning
motors, elevator motors, and factory loads).
Site wiring and DC power requirements
The following are required for all installations using DC power supplies:
• All DC mains and supply conductors to power distribution boxes for the rack-mounted system must
comply with local, national, or other applicable government codes and regulations.
• Ensure that the voltage of your power source matches the voltage inscribed on the equipment’s
electrical label.
• To ensure redundancy, provide two separate power sources for the enclosures. These power sources
must be independent of each other, and each must be controlled by a separate circuit breaker at the
power distribution point.
• The system requires voltages within minimum fluctuation. The customer-supplied facilities’ voltage must
maintain a voltage within the range specified on the equipment’s electrical rating label. The customer
facilities must also provide suitable surge protection.
• Site wiring must include an earth ground connection to the DC power source. Grounding must comply
with local, national, or other applicable government codes and regulations.
• Power circuits and associated circuit breakers must provide sufficient power and overload protection.

Weight and placement guidelines
• The weight of an enclosure depends on the number and type of modules installed.
• Ideally, use two people to lift an enclosure. However, one person can safely lift an enclosure if its
weight is reduced by removing the power and cooling modules and drive modules.
• Do not place enclosures in a vertical position. Always install and operate the enclosures in a horizontal
orientation.
• When installing enclosures in a rack, make sure that any surfaces over which you might move the rack
can support the weight. To prevent accidents when moving equipment, especially on sloped loading
docks and up ramps to raised floors, ensure you have a sufficient number of helpers. Remove obstacles
such as cables and other objects from the floor.
• To prevent the rack from tipping and to minimize personnel injury in the event of a seismic occurrence,
securely anchor the rack to a wall or other rigid structure that is attached to both the floor and to the
ceiling of the room.
Electrical guidelines
• These enclosures work with single-phase power systems having an earth ground connection. To reduce
the risk of electric shock, do not plug an enclosure into any other type of power system. Contact your
facilities manager or a qualified electrician if you are not sure what type of power is supplied to your
building.
• Enclosures are shipped with a grounding-type (three-wire) power cord. To reduce the risk of electric
shock, always plug the cord into a grounded power outlet.
• Do not use household extension cords with the enclosures. Not all power cords have the same current
ratings. Household extension cords do not have overload protection and are not meant for use with
computer systems.
Ventilation requirements
• Do not block or cover ventilation openings at the front and rear of an enclosure. Never place an
enclosure near a radiator or heating vent. Failure to follow these guidelines can cause overheating and
affect the reliability and warranty of your enclosure.
• Leave a minimum of 6 inches (15 cm) at the front and back of each enclosure to ensure adequate
airflow for cooling. No cooling clearance is required on the sides, top, or bottom of enclosures.
• Leave enough space in front and in back of an enclosure to allow access to enclosure components for
servicing. Removing a component requires a clearance of at least 15 inches (37 cm) in front of and
behind the enclosure.
Cabling requirements
• Keep power and interface cables clear of foot traffic. Route cables in locations that protect the cables
from damage.
• Route interface cables away from motors and other sources of magnetic or radio frequency
interference.
• Stay within the cable length limitations.
Management host requirements
A local management host with at least one serial port connection is recommended for the initial installation
and configuration of a controller enclosure. After you configure one or both of the controller modules with
an Internet Protocol (IP) address, you then use a remote management host on an Ethernet network to
configure, manage, and monitor.

NOTE: Connections to this device must be made with shielded cables with metallic RFI/EMI connector
hoods in order to maintain compliance with FCC Rules and Regulations.
Physical requirements
The floor space at the installation site must be strong enough to support the combined weight of the rack,
controller enclosures, expansion enclosures, and any additional equipment. The site also requires sufficient
space for installation, operation, and servicing the enclosures, and also requires sufficient ventilation to
allow a free flow of air to all enclosures.
Table 14 and Table 15 list enclosure dimensions and weights. Weights are based on an enclosure having
12 drive modules, two controller or expansion modules, and two power supplies installed.

Each enclosure has two power and cooling modules for redundancy. If full redundancy is required, use a
separate power source for each module. The AC power supply unit in each power and cooling module is
auto-ranging and is automatically configured to an input voltage range from 88–264 VAC with an input
frequency of 47–63 Hz. The power and cooling modules meet standard voltage requirements for both U.S.
and international operation. The power and cooling modules use standard industrial wiring with
line-to-neutral or line-to-line power connections.
Power cord requirements
Each enclosure is shipped with two AC power cords that are appropriate for use in a typical outlet in the
destination country. Each power cord connects one of the power and cooling modules to an independent,
external power source. To ensure power redundancy, connect the two power cords to two separate circuits;
for example, to one commercial circuit and one uninterruptible power source (UPS).

C Electrostatic discharge
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you need to follow when setting up the
system or handling parts. A discharge of static electricity from a finger or other conductor may damage
system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the
device.
To prevent electrostatic damage:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods to prevent electrostatic discharge
Several methods are used for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
• Use a wrist strap connected by a ground card to a grounded workstation or computer chassis. Wrist
straps are flexible straps with a minimum of 1 megohm ± 10 percent resistance in the ground cords. To
provide proper ground, wear the strap snug against the skin.
• Use heel straps, toe straps or boot straps at standing workstations. Wear the straps on both feet when
standing on conductive floors or dissipating floor mats.
• Use conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized reseller
install the part.
For more information on static electricity or assistance with product installation, contact an authorized
reseller.

Regulatory compliance
Federal Communications Commission notice
Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio
Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic
devices, including computers, generate RF energy incidental to their intended function and are, therefore,
covered by these rules. These rules place computers and related peripheral devices into two classes, A and
B, depending upon their intended installation. Class A devices are those that may reasonably be expected
to be installed in a business or commercial environment. Class B devices are those that may reasonably be
expected to be installed in a residential environment (i.e., personal computers). The FCC requires devices
in both classes to bear a label indicating the interference potential of the device as well as additional
operating instructions for the user.
The rating label on the device shows which class (A or B) the equipment falls into. Class B devices have an
FCC logo or FCC ID on the label. Class A devices do not have an FCC logo or FCC ID on the label. Once
the class of the device is determined, refer to the following corresponding statement.
Class A equipment
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be required to correct the
interference at personal expense.
Class B equipment
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit that is different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio or television technician for help.
Declaration of conformity for products marked with the FCC logo, United States
only
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference
