Introduction  
Power supply  
The power supply converts standard 110 or 230 VAC to DC voltages for the various switch  
circuits. Four internal fans provide cooling. The switch monitors internal air temperature, and  
therefore does not monitor or report fan operational status. Air flows into the switch from the  
bezel side and is exhausted from the port side of the switch.  
To apply power to the switch, plug the power cord into the switch AC receptacle, and then into  
a 110 or 230 VAC power source.  
Note: The power supply and fans are not field replaceable units.  
Serial port  
The switch is equipped with an RS-232 serial port, to access the Command Line Interface for  
advanced configuration tasks and maintenance purposes. (Figure 1)  
The serial port connector requires a null-modem female/female DB9 cable, using the pin  
configuration and connection information as detailed in “Cable pin configurations” on  
Chassis LEDs  
The chassis LEDs (Figure 2) provide status information about switch operation.

Introduction  
Heartbeat LED (green)  
The Heartbeat LED indicates the status of the internal switch processor and the results of the  
Power On Self Test (POST).  
Following a normal power-up, the Heartbeat LED blinks about once per second to indicate  
that the switch passed the POST and that the internal switch processor is running. In  
maintenance mode, the Heartbeat LED illuminates continuously. The Heartbeat LED also  
shows a blink code for POST errors and the over temperature condition. See “Heartbeat LED  
System Fault LED (solid amber)  
The System Fault LED illuminates to indicate an over temperature condition or a POST error  
and the Heartbeat LED shows a blink code that defines the condition. See “Heartbeat LED  
Ethernet port  
The Ethernet port (Figure 3) is an RJ-45 connector that provides a connection to a  
management workstation through a 10/100 Base-T Ethernet cable. The workstation can be a  
Windows® or a Linux® workstation that is used for advanced configuration and management  
tasks. You can manage the switch over the Ethernet connection using Switch Manager, the  
Command Line Interface (CLI), or SNMP. The switch through which the fabric is managed is  
called the fabric management switch.

Introduction  
Maintenance button  
The Maintenance button is a dual-function momentary switch on the front panel. (Figure 1)  
Its purpose is to reset the switch or place the switch in maintenance mode. See “Maintenance  
mode options” on page 47 for more information.  
Resetting the switch  
Use a pointed tool, such as an opened paper clip, to momentarily press and release (less than 2  
seconds) the Maintenance button.  
The switch responds as follows:  
All chassis LEDs illuminate, and then the System Fault LED extinguishes, leaving only  
the Input Power LED and Heartbeat LED illuminated.  
After approximately 1 minute, the power-on self test (POST) begins, extinguishing the  
Heartbeat LED.  
When the POST is complete, the Input Power LED is illuminated and the Heartbeat LED  
flashes once per second.  
Placing the switch in maintenance mode  
1. Isolate the switch from the fabric.  
2. Press and hold the Maintenance button with a pointed tool until the Heartbeat LED alone  
is illuminated (between 2–7 seconds).  
3. After approximately 1 minute, the POST begins illuminating all chassis LEDs.  
4. When the POST is complete, the chassis LEDs extinguish, leaving only the Heartbeat  
LED illuminated. The Heartbeat LED illuminates continuously while the switch is in  
maintenance mode.  
Exiting maintenance mode  
To exit maintenance mode and return to normal operation, momentarily press and release the  
Maintenance button to reset the switch.

Introduction  
Fibre Channel ports and LEDs  
The switch has eight Fibre Channel ports, numbered 0–7. (Figure 4)  
Each Fibre Channel port is served by a 2 Gbps Small Form-Factor Pluggable (SFP) optical  
transceiver. SFPs are hot-pluggable. User ports self-discover both the port type and  
transmission speed of the connected devices. The Fibre Channel port LEDs are located above  
their respective ports and provide port log-in and activity status information.

Figure 4: Fibre Channel port and LED locations  
Port Logged-in LED (green)  
The Logged-in LED indicates the logged-in or initialization status of the connected devices.  
After successful completion of the POST, the switch extinguishes all Logged-in LEDs.  
Following a successful loop initialization or port login, the switch illuminates the  
corresponding logged-in LED. This shows that the port is properly connected and able to  
communicate with its attached devices. The Logged-in LED remains illuminated as long as the  
port is initialized or logged in. If the port connection is broken or an error occurs that disables  
information.  
Port Activity LED (green)  
The Activity LED indicates that data is passing through the port. Each frame that the port  
transmits or receives causes this LED to illuminate for 50 milliseconds. This makes it possible  
to observe the transmission of a single frame. When extending credits, the Activity LED for a  
donor port will reflect the traffic of the recipient port. See “Distance” on page 24 for more  
information about extended credits and donor ports.

Introduction  
SFP transceivers  
The switch supports SFP optical transceivers for the Fibre Channel ports. A transceiver  
converts electrical signals to and from optical laser signals to transmit and receive data.  
Duplex fiber optic cables plug into the transceivers, which then connect to the devices. A Fibre  
Channel port is capable of transmitting at 1 Gbps or 2 Gbps; however, the transceiver must be  
capable of 2 Gbps for the port to deliver at that rate.  
SFP transceivers are hot pluggable. This means that you can remove or install a transceiver  
while the switch is operating, without harming the switch or the transceiver. However,  
communication with the connected device is interrupted. See “Install SFP transceivers” on  
page 34 for information.  
Port types  
The switch supports generic ports (G_Port, GL_Port) and fabric ports (F_Port, FL_Port).  
Switches come from the factory with all Fibre Channel ports configured as GL_Ports.  
Ports function as follows:  
A GL_Port self-configures as an FL_Port when connected to a public loop device, and as  
an F_Port when connected to a single public device.  
A G_Port self-configures as an F_Port when connected to a single public device.  
An FL_Port supports a loop of up to 126 public devices. An FL_Port can also configure  
itself during the fabric login process as an F_Port when connected to a single public device  
(N_Port).  
An F_Port supports a single public device. If the device is a single device on a loop, the  
GL_Port will attempt to configure first as an F_Port, then if that fails, as an FL_Port.

Introduction  
Switch management  
Fabrics are managed with following tools:  
Switch Manager user interface  
Switch Manager is a workstation-based Java® application that provides a graphical user  
interface for fabric management. This application runs on a Windows or Linux workstation. A  
management workstation connects to the fabric through the Ethernet port of one or more  
switches and can provide in-band management for all other switches in the fabric. See  
“Management System Requirements” on page 63 for connection information and to the HP  
StorageWorks 2/8q Fibre Channel Switch Management User Guide for information about  
Switch Manager.  
Command Line Interface  
The CLI provides monitoring and configuration functions by which the administrator can  
manage the fabric and its switches, and can be accessed over an Ethernet connection or a serial  
connection. See “Management System Requirements” on page 63 for connection information  
and refer to the HP StorageWorks 2/8q Fibre Channel Switch Management User Guide for  
information about the CLI.  
File Transfer Protocol  
FTP provides the command line interface for exchanging files between the switch and the  
management workstation. These files include firmware image files, configuration files, and  
log files.  
Simple Network Management Protocol  
SNMP provides monitoring and trap functions for the fabric. This switch supports SNMP  
versions 1 and 2, the Fibre Alliance Management Information Base (FA-MIB) version 4.0, and  
the Fabric Element Management Information Base (FE-MIB) RFC 2837. Traps can be  
formatted using SNMP version 1 or 2. Refer to the HP StorageWorks 2/8q Fibre Channel  
Switch SNMP Reference Guide for more information.

Consider the following when planning a fabric:  
21

Planning  
Devices  
When planning a fabric, consider the number of public devices and the anticipated demand.  
This determines the number of ports that are needed and in turn the number of switches.  
Consider how many and what types of switches are needed.  
Consider the distribution of targets and initiators. An F_Port supports a single public device.  
An FL_Port can support up to 126 public devices in an arbitrated loop.  
Device access  
Consider device access needs within the fabric. Access is controlled by the use of zones and  
zone sets.  
Some zoning strategies include:  
Grouping devices by operating system.  
Separating devices that have no need to communicate with other devices in the fabric or  
have classified data.  
Separating devices into department, administrative, or other functional group.  
Reserving a path and its bandwidth from one port to another.  
A zone is a named group of devices that can communicate with each other. Membership in a  
zone can be defined by domain ID and switch port number, port Fibre Channel address, or by  
device worldwide name (WWN). Devices can communicate only with devices within the same  
zone. A zone can be a member of more than one zone set. Several zone sets can be defined for  
a fabric, but only one zone set can be active at one time. The active zone set determines the  
current fabric zoning.  
A zoning database is maintained on each switch consisting of all inactive zone sets, the active  
zone set, all zones, aliases, and their membership. Refer to the HP StorageWorks 2/8q Fibre  
Channel Switch Management User Guide for more information about zoning.  
The two types of zones are:

Hard zones (Access Control Lists)  
Access Control List (ACL) zoning divides the fabric for purposes of controlling discovery and  
inbound traffic. ACL zoning is a type of hard zoning that is hardware enforced. This type of  
zoning is useful for controlling access to certain devices without totally isolating them from  
the fabric. Members can communicate with each other and transmit outside the ACL zone, but  
cannot receive inbound traffic from outside the zone. The following rules apply to ACL zones:  
The ACL zone boundary is secure against inbound traffic.  
ACL zones can overlap; that is, a port can be a member of more than one ACL zone.  
ACL zone boundaries supersede soft zone boundaries.  
Membership can be defined only by domain ID and port ID. A switch port can be a  
member of multiple ACL zones whose combined membership does not exceed 128.  
Soft zones  
Soft zoning divides the fabric for purposes of controlling device discovery. Devices in the  
same soft zone automatically discover and communicate freely with all other members of the  
same zone. The soft zone boundary is not secure; traffic across soft zones can occur if  
addressed correctly. The following rules apply to soft zones:  
Soft zone boundaries yield to ACL zone boundaries.  
Soft zones can overlap; that is, a port can be a member of more than one soft zone.  
Membership can be defined by Fibre Channel address, domain ID and port number, or  
worldwide name.  
Soft zoning supports FL_Ports and F_Ports.

Planning  
Performance  
The switch supports class 2 and class 3 Fibre Channel service at transmission rates of 2 Gbps,  
with a maximum frame size of 2148 bytes.  
Related performance characteristics include:  
Distance  
Consider the physical distribution of devices and switches in the fabric. See “Specifications”  
on page 59 for more information about cable types and transceivers.  
Each Fibre Channel port is supported by a data buffer with a 16 credit capacity; that is, 16  
maximum sized frames. For fiber optic cables, this enables full bandwidth over a distance of  
13 kilometers at 2 Gbps (1.2 credits/Km). Beyond this distance, however, there is some loss of  
efficiency because the transmitting port must wait for an acknowledgement before sending the  
next frame.  
Longer distances can be spanned at full bandwidth by extending credits to the ports. Each port  
can donate 15 credits to a pool from which a recipient port can borrow. The recipient port also  
loses a credit in the process. For example, you can configure a recipient port to borrow 15  
credits from one donor port for a total of 30 credits (15+15=30). This supports communication  
over approximately 25 Km at 2 Gbps (30÷1.2).  
Bandwidth  
Latency  
Bandwidth is a measure of the volume of data that can be transmitted at a given transmission  
rate. The Fibre Channel ports transmit and receive at a rate of 2 Gbps, for a maximum  
bandwidth of 200 MB.  
Latency is a measure of how fast a frame travels from one port to another. Factors that affect  
latency include transmission rate and the source/destination port relationship. 2 Gbps to  
2 Gbps transmissions have a latency factor < 0.4 µsec.

Planning  
Fabric security  
Fabric security consists of the following:  
User account security  
User account security consists of account names, passwords, expiration dates, and authority  
levels. If an account has Admin authority, all management tasks can be performed by that  
account in both Switch Manager and the CLI. Without Admin authority, only monitoring tasks  
are available. The default account name, Admin, is the only account that can create or change  
account names and passwords. Account names and passwords are required when connecting to  
a switch. Consider your management needs and determine the number of user accounts, their  
authority needs, and expiration dates.  
Simple Network Management Protocol security  
SNMP is the protocol governing network management and monitoring of network devices,  
and is enabled by default. SNMP security consists of a read community string and a write  
community string, which are the passwords that control read and write access to the switch.  
The read community string ("public") and write community string ("private") are set at the  
factory to these well-known defaults and should be changed. If the read and write community  
strings have not been changed from their defaults, you risk unwanted access to the switch.  
Fabric management  
Switch Manager and the CLI execute on a management workstation that provides for the  
advanced configuration, control, and maintenance of the fabric. Supported platforms include  
Windows and Linux. Consider how many fabrics will be managed, how many management  
workstations are needed, and whether the fabrics will be managed with the CLI or Switch  
Manager.  
A switch supports a combined maximum of 19 logins reserved as follows:  
4 logins or sessions for internal applications such as management server and SNMP  
9 high priority Telnet sessions  
6 logins or sessions for Switch Manager logins and Telnet logins. Additional logins are  
refused.  
See “Management System Requirements” on page 63 for connection information and refer to  
the HP StorageWorks 2/8q Fibre Channel Switch Management User Guide for information  
about using these management tools.

Backing up the switch configuration  
Backing up and restoring a configuration is useful to protect your work or to use as a template  
in configuring other switches. The CLI Config Backupcommand creates a file on the  
switch, named configdata. This file can be used to restore a switch configuration only from  
the command line interface; it cannot be used to restore a switch using Switch Manager.  
The configdatafile contains all of the switch configuration information including:  
All named switch configurations, including the default configuration. This includes port,  
switch, port threshold alarm, and zoning configuration components.  
All SNMP and network information defined with the Set Setup command.  
The zoning database included all zone sets, zones, and aliases.  
Use FTP to download the configdatafile to your workstation for safe keeping and to  
upload the file back to the switch for the restore function.  
See “Management System Requirements” on page 63 for information about connecting a  
workstation to the switch and refer to “Backing up a switch configuration” in the HP  
StorageWorks 2/8q Fibre Channel Switch Management User Guide, for procedural details.  
Powering down the switch  
Simply unplugging the switch from the power source does not allow the switch to complete  
executing tasks and could lead to flash memory corruption.  
To initiate an orderly shut down, access the CLI and execute the Shutdowncommand. Then,  
power down the switch by unplugging the power cord.  
See“Management System Requirements” on page 63 for information about connecting a  
workstation to the switch and refer to the HP StorageWorks 2/8q Fibre Channel Switch

Updating switch firmware  
The switch comes with firmware installed. You can upgrade the firmware from the  
management workstation as new firmware becomes available. Firmware updates are availabe  
on the MSA1000 web site at www.hp.com/go/msa1000  
.
See“Management System Requirements” on page 63 for information about connecting a  
workstation to the switch and refer to the HP StorageWorks 2/8q Fibre Channel Switch  
Management User Guide for detailed information about Switch Manager and the CLI.  
Note: You can load and activate new firmware on an operating switch without disrupting data  
traffic or having to re-initialize attached devices. If you attempt to perform a non-disruptive  
activation without satisfying the following conditions, the switch will perform a disruptive activation:  
No changes are being made to switches in the fabric including powering up, powering down,  
and changing the switch configuration.  
No port in the fabric is in the diagnostic state.  
No zoning changes are being made in the fabric.  
No changes are being made to attached devices including powering up, powering down,  
disconnecting, connecting, and HBA configuration changes.  
Ports that are stable when the non-disruptive activation begins, but then change states, are reset.  
When the non-disruptive activation is complete, Switch Manager sessions reconnect automatically.  
However, Telnet sessions must be restarted manually.

Diagnostic information about the switch is available through the chassis LEDs and the port  
LEDs. Diagnostic information is also available through the Switch Manager and CLI event  
logs and error displays.  
This section describes the following diagnostics and tasks:  
41  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
Troubleshooting  
POST diagnostics  
The switch performs a series of tests as part of its power-up procedure. The POST diagnostic  
program performs checksum tests on the boot firmware in PROM and the switch firmware in  
flash memory, internal data loopback tests on all ports, and access and integrity tests on the  
ASIC.  
During the POST, the switch logs any errors encountered. Some POST errors are critical,  
others are not. The switch uses the Heartbeat LED and the Logged-In LED to indicate switch  
and port status. A critical error disables the switch so that it does not operate. A non-critical  
error allows the switch to operate, but disables the ports that have errors. Whether the problem  
is critical or not, contact your HP Authorized Maintenance Provider.  
If there are no errors, the Heartbeat LED blinks at a steady rate of once per second. If a critical  
error occurs, the Heartbeat LED shows an error blink pattern and the System Fault LED will  
illuminate. If there are non-critical errors, the switch disables the failed ports and flashes the  
associated Logged-In LEDs.  
Heartbeat LED blink patterns  
The Heartbeat LED indicates the operational status of the switch. When the POST completes  
with no errors, the Heartbeat LED blinks at a steady rate of once per second. When the switch  
is in maintenance mode, the Heartbeat LED illuminates continuously. See “Maintenance mode  
options” on page 47 for more information about maintenance mode. All other blink patterns  
indicate critical errors.  
The Heartbeat LED shows an error blink pattern for the following conditions:  
Blinking pattern

2-blink error pattern indicates that the firmware has failed, and that the switch must be reset.  
Momentarily press and release the Maintenance button to reset the switch.  
System error blink pattern  
A system error blink pattern is 3 blinks followed by a two second pause. The 3-blink error  
pattern indicates that a POST failure or a system error has left the switch inoperable. If a  
system error occurs, contact your HP Authorized Maintenance provider. Momentarily press  
and release the Maintenance button to reset the switch.  
Configuration file system error blink pattern  
A configuration file system error blink pattern is 4 blinks followed by a two second pause. The  
4-blink error pattern indicates that a configuration file system error has occurred, and that the  
configuration file must be recreated. See “Maintenance mode options” on page 47 for more  
information. To recreate the configuration file:  
Note: Recreating the configuration file deletes all switch configuration settings.  
1. Place the switch in maintenance mode. Press and hold the Maintenance button for 2–7  
seconds. See “Maintenance mode options” on page 47 for more information.  
2. Establish a Telnet session using the default IP address 10.0.0.1, or the user assigned IP

Troubleshooting  
Over temperature blink pattern  
An over temperature blink pattern is 5 blinks followed by a two second pause. The 5-blink  
error pattern indicates that the air temperature inside the switch has exceeded the failure  
temperature threshold (70° C) and all ports are down.  
If the Heartbeat LED shows the over temperature blink pattern:  
1. Inspect the chassis fans and vents. Are the intake and exhaust vents clear? Are the fans  
operating and producing air flow?  
Yes - Continue.  
— No - Remove any debris from fan intake and exhaust if necessary. If the condition  
remains, continue.  
2. Consider the ambient air temperature near the switch and clearance around the switch.  
Make necessary corrections. If the condition remains, unplug the switch from the AC  
power source, and contact your HP Authorized Maintenance Provider.  
3. Open a command line window and log on to the switch. Enter the Shutdown command,  
then power down the switch. Contact your HP Authorized Maintenance Provider.

Troubleshooting  
Port Error blinking pattern  
The switch can monitor a set of port errors and generates alarms based on user-defined sample  
windows and thresholds. Port errors include the following:  
CRC errors  
Decode errors  
Login / Logout errors  
Loss-of-signal errors  
Port threshold alarm monitoring is disabled by default. Refer to the HP StorageWorks 2/8q  
Fibre Channel Switch Management User Guide for information about managing port  
threshold alarms.  
If the count for any of these errors exceeds the rising trigger for three consecutive sample  
windows, the switch generates an alarm and disables the affected port, changing its  
operational state to “down.”  
Port errors can be caused by the following:  
Triggers are too low or the sample window is too small  
Faulty Fibre Channel port cable  
Faulty SFP  
Faulty port  
Faulty storage device, HBA, or server  
Review the event browser to determine if excessive port errors are responsible for disabling  
the port. Look for a message that mentions one of the monitored error types indicating that the  
port has been disabled, then do the following:  
1. Examine the alarm configuration for the associated error using the CLI Show Config  
Thresholdcommand or the Switch Manager application.  
Are the thresholds and sample window correct?  
Yes - Continue.  
— No - Correct the alarm configuration. If the condition remains, continue.  
2. Reset the port, then perform an external port loopback test to validate the port and the SFP.  
Does the port pass the test?  
Yes - Continue.  
— No - Reseat or replace the SFP and repeat the test. If the port does not pass the test,  
contact your HP Authorized Service Provider. Otherwise continue.  
3. Replace the Fibre Channel port cable.  
Is the problem corrected?  
Yes - Complete.  
— No - Continue.  
4. Inspect the device (server or storage) to which the affected port is connected and confirm  
that the device is working properly. Make repairs and corrections as needed. If the  
condition remains, contact your HP Authorized Service Provider.

Regulatory Compliance Notices  
A
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 (personal computers, for  
example). 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 different from that to which the receiver  
is connected.  
Consult the dealer or an experienced radio or television technician for help.

Electrostatic Discharge  
B
To prevent damage to 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.  
Prevention methods  
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 make sure you are properly grounded when touching a static-sensitive component  
or assembly.  
Grounding methods  
There are several methods 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 cord 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 equipment suggested for proper grounding, either have an HP  
Authorized Reseller install the part or discharge any potential static by touching a piece of  
sheet metal immediately before touching the component or the device.  
Note: For more information on static electricity, or assistance with product installation, contact your  
HP Authorized Reseller.
