Brocade 4Gb SAN Switch for HP c-Class BladeSystem installation  
instructions  
Installation and safety considerations  
The 4Gb SAN Switch installs in the I/O bays in the rear of the HP c-Class BladeSystem  
enclosure. Refer to the appropriate BladeSystem Enclosure Setup and Installation Guide  
for specific enclosure requirements.  
Installing multiple switches  
Install and configure one 4Gb SAN Switch at a time. This is required so that Ethernet IP  
address conflicts do not occur with duplicate default Ethernet IP addresses.  
IMPORTANT:  
DHCP is enabled by default for switches running Fabric OS 5.2.1b (switch rev 0C) or later.  
In cases where DHCP is available, IP address conflicts will not occur, simplifying multiple  
switch installations. See Using External DHCP.  
22  
Setup  
Download from Www.Somanuals.com. All Manuals Search And Download.  
         
Each switch must be assigned a unique Ethernet IP address during configuration. Once  
the default Ethernet IP address on the 4Gb SAN Switch has been changed, you may  
install additional 4Gb SAN Switches in the enclosure.  
See the appropriate HP BladeSystem Enclosure Setup and Installation Guide for help  
identifying your specific enclosure setup, available connections and power requirements.  
Electrical considerations  
The 4Gb SAN Switch requires 35 watts, provided by the enclosure. No other power  
requirement or provision exists.  
Environmental considerations  
Ensure proper cooling and ventilation by verifying the following:  
•
•
The air vents on the enclosure are not blocked or restricted.  
The ambient air temperature at the front of the enclosure does not exceed 35°C  
(95°F) while the switch is operating.  
IMPORTANT:  
The dust covers that ship with your 4Gb SAN switch must be inserted into any ports  
where SFPs are not installed, to help contain air flow in the BladeSystem chassis.

Install the 4Gb SAN Switch  
CAUTION:  
For switch revision levels 0A and 0B only (running Fabric OS versions earlier than  
5.2.1b) — DHCP is not supported on these models. Do not install multiple switches  
at the same time with default addresses, as address conflicts will occur. Locate switch  
revision levels on the switch or shipping carton. See Set the IP address.  
For switch revision levels 0C and above only (Fabric OS 5.2.1b or later) — DHCP is  
supported and enabled by default for switches running Fabric OS 5.2.1b (switch rev  
0C) or later. In this case, IP address conflicts will not occur during multiple switch  
installations. Locate switch revision levels on the switch or shipping carton. See  
Using External DHCP.  
The Brocade 4Gb SAN switch is a hot-pluggable device. The enclosure power may be  
on or off when inserting the switch. Follow these steps to install the 4Gb SAN Switch.  
1. Locate the appropriate interconnect bay in the rear of the enclosure per the  
appropriate HP BladeSystem Enclosure Setup and Installation Guide provided with  
your enclosure.  
Remove the slot cover (if installed).  
IMPORTANT:  
Populate all enclosure I/O bays with the appropriate component (for  
example a switch, Pass-Thru or one of the blank panels provided with  
the enclosure).  
CAUTION:  
Properly ground yourself before handling the switch.  
2. Press the handle latch to release the installation handle. See Figure 4.

OA verifies power  
As defined earlier, the HP BladeSystem Onboard Administrator (OA) is the enclosure  
management processor that manages the devices contained within the enclosure. The  
OA provides a single point from which to perform basic management tasks on switches  
or server blades installed in the enclosure.  
IMPORTANT:  
HP recommends reading the appropriate HP BladeSystem Enclosure User Guide and the HP  
BladeSystem Onboard Administrator User Guide. Reading these guides in sequence will  
promote an overall understanding of your specific enclosure model.  
Once the switch is installed in the interconnect bay, the OA verifies that the switch  
type matches the mezzanine cards present on the servers. If there is no mismatch, the  
OA powers up the switch.  
If the switch does not power up, check the enclosure and switch status via the OA web  
interface. Refer to the HP BladeSystem Onboard Administrator User Guide.

Setting the IP address  
IMPORTANT:  
The switch supports DHCP beginning with Fabric OS 5.2.1b firmware. For  
switches running Fabric OS 5.2.1b (switch rev 0C) or later, DHCP is enabled by  
default, simplifying multiple switch installations. To enable or disable this feature,  
login with these default credentials and issue the ipaddrset command using:  
•
•
username: admin  
password: password  
To set the Ethernet IP address:  
1. Verify that the enclosure is powered on.  
2. Verify that the switch is installed.  
3. Choose one of the following methods to set the Ethernet IP address:  
•
•
•
Using Enclosure Bay IP Addressing (EBIPA)  
Using External DHCP  
Setting the IP address manually  
Using Enclosure Bay IP Addressing (EBIPA)  
To set the Ethernet IP address using EBIPA:  
1. Connect to the active OA via a web browser.  
2. Enable EBIPA for the corresponding interconnect bay.  
3. Click the Apply button to restart the switch.  
4. Verify the IP address using a telnet or ssh login to the switch, or by selecting the

Rack Overview window.  
3. Verify the IP address using a telnet or ssh login to the switch, or by selecting the  
switch in the OA GUI Rack Overview window.  
Setting the IP address manually  
IP addresses must be set manually for 4Gb SAN Switches with revision levels prior to  
rev 0C (running Fabric OS versions earlier than 5.2.1b). Switches with revision levels  
earlier than rev 0C do not support DHCP. Set IP addresses for these switches manually  
as follows:  
NOTE:  
As an alternate method to using a null modem cable, use telnet or ssh to access the IP  
address of the Onboard Administrator, resuming at step 9 below.  
1. Obtain the following items to set the IP address via a serial connection:  
•
Computer with a terminal application (such as HyperTerminal in a Windows  
environment or TERM in a UNIX environment)  
•
Null modem serial cable  
2. Replace the default IP address (if present) and related information with the  
information provided by your network administrator. By default, the IP address is set  
to 10.77.77.77 for switches with revision levels earlier than 0C.  
3. Verify that the enclosure is powered on.  
4. Identify the active OA in the BladeSystem.  
5. Connect a Null modem serial cable from your computer to the serial port of the  
active OA.

1. If you have not already done so, connect to the switch and log in as admin as  
described in Connect to the Command Line Interface.  
2. Issue the date command using the following syntax:  
date “mmddHHMMyy”  
where:  
•
•
•
•
•
mm is the month; valid values are 01 through 12.  
dd is the date; valid values are 01 through 31.  
HH is the hour; valid values are 00 through 23.  
MM is minutes; valid values are 00 through 59.  
yy is the year; valid values are 00 through 99 (values greater than 69  
are interpreted as 1970–1999, and values less than 70 are interpreted as  
2000–2069).  
For example:  
switch:admin> date  
Fri Jan 29 17:01:48 UTC 2000  
switch:admin> date "0227123003  
Thu Feb 27 12:30:00 UTC 2003

Modifying the FC domain ID (optional)  
If desired, you can modify the FC domain ID. The default FC domain ID is domain 1. If  
the 4Gb SAN Switch is not powered on until after it is connected to the fabric and the  
default FC domain ID is already in use, the domain ID for the new switch is automatically  
reset to a unique value. If the switch is connected to the fabric after is has been powered  
on and the default domain ID is already in use, the fabric segments.  
Type fabricshow to determine the domain IDs that are currently in use. The maximum  
number of domains with which the 4Gb SAN Switch communicates is determined by  
this switch’s fabric license.  
To modify the domain ID:  
1. Type switchdisable to disable the switch.  
2. Type configure, then type a new value.  
Or press Enter to accept each default value.  
3. At the Fabric parameters prompt, type Y and press Enter:

Disabling and enabling a switch  
By default, the switch is enabled after power on and diagnostics and switch initialization  
routines complete. You can disable and re-enable the switch as necessary.  
To disable:  
1. If you have not already done so, connect to the switch and log in as admin as  
described in Connect to the Command Line Interface.  
2. Issue the switchDisable command.  
All Fibre Channel ports on the switch are taken offline. If the switch was part of a  
fabric, the fabric reconfigures.  
To enable:  
1. If you have not already done so, connect to the switch and log in as admin as  
described in Connect to the Command Line Interface.  
2. Issue the switchEnable command.  
All Fibre Channel ports that pass the Power-on Self Test (POST) are enabled. If the

Using Dynamic Ports On Demand (DPOD)  
In the past, Ports On Demand (POD) functionality was static. A preset group of ports  
were individually enabled per each POD license. In contrast, the new DPOD functionality  
does not require a predefined assignment of ports. Port assignment is determined by the  
total number of ports in use as well as the number of purchased ports.  
In summary, the DPOD feature simplifies port management by:  
•
•
•
automatically detecting HBA connected server ports or cabled ports.  
automatically enabling ports  
automatically assigning port licenses  
To initiate DPOD, use the licensePort command, as described in DPOD commands.  
IMPORTANT:  
For the Brocade 4Gb SAN Switch, DPOD works only if the server blade is installed  
with an HBA present. A server blade that does not have a functioning HBA will not be  
treated as an active link for the purpose of initial POD port assignment.  
DPOD commands  
Use the licensePort command to manage dynamic POD assignments with the  
following options:  
•
licensePort –reserve portnum reserves a future license assignment for a  
specific port, even if the port is currently offline.  
•
•
•
licensePort –release portnum removes a license from a port.  
portCfgPersistentDisable blocks a specific port from future assignments.  
licensePort -show displays an overview of the POD license status and port  
assignments.  
The following shows examples of the licensePort -show command for a Brocade  
4/12 SAN Switch and a Brocade 4/24 SAN Switch:

Maintaining the 4Gb SAN Switch  
The 4Gb SAN Switch does not require any regular physical maintenance.  
However, it is critical that environmental conditions, described in Environmental  
requirements are met to help prevent switch failure due to heat stress or improper air flow.  
Installing dust covers in empty ports  
The dust covers included in the 4GB SAN Switch shipping carton, (see Figure 1) must  
be inserted in ports where SFPs are not installed. Installing dust covers ensures proper  
airflow and helps reduce dust contamination of the switch.  
Replacing an SFP transceiver  
In some cases you might need to reinstall an SFP transceiver.  
To remove an SFP transceiver:  
1. Press and hold the cable release.  
2. Remove the cable from the transceiver.  
3. Pull the bail (wire handle) to release the transceiver.  
4. Grasp the bail, and gently but firmly pull the transceiver out of the port.  
5. Repeat this procedure for the remaining ports as required.

Diagnostic tests  
In addition to POST, Fabric OS 5.x includes diagnostic tests to help troubleshoot the  
hardware and the firmware including tests of internal connections and circuitry, fixed  
media, and the transceivers and cables in use.  
Initiate diagnostic tests via the command line, using a telnet session or a terminal setup  
with a serial connection to the switch. Some tests require the ports to be connected  
by external cables to allow diagnostics to verify the serializer/deserializer interface,  
transceiver, and cable. For information on available diagnostic tests, type diagHelp.  
All diagnostic tests are run at link speeds of 1 Gb/sec, 2 Gb/sec, and 4 Gb/sec.

CAUTION:  
Diagnostic tests can temporarily lock the transmit and receive speed of the links during  
diagnostic testing.  
For information about specific diagnostic tests, refer to the latest version of the HP  
StorageWorks Fabric OS administrator guide or type help followed by the name of  
the diagnostic test.  
Powering on and off  
4Gb SAN Switch power is provided by the enclosure. The 4Gb SAN Switch will run  
POST by default each time power to the enclosure is turned on. The POST process  
can last as long as three minutes.  
To remove power from the switch, remove the 4Gb SAN Switch from the enclosure  
interconnect bay.  
NOTE:  
Each time the 4Gb SAN Switch is powered on, its settings are restored to the last  
saved configuration.  
Interpreting LED activity  
You can monitor switch activity and status by checking 4Gb SAN Switch LEDs.  
There are three possible LED states: no light, a steady light, or a flashing light. The  
steady lights and flashing lights can be green or amber.  
The LEDs flash any of these colors during boot, POST, or other diagnostic tests. This is  
normal and does not indicate a problem unless the LEDs do not indicate a healthy state  
after all boot processes and diagnostic tests are complete. A healthy state is indicated  
by a steady green light. See Table 12 for details about LED activity.

POST and boot specifications  
POST is a system check that is performed each time the switch is powered on, rebooted,  
or reset. During POST, the LEDs flash different colors. Any errors that occur during  
POST are listed in the error log.  
The 4Gb SAN Switch performs POST when it is turned on or rebooted. Total boot time  
with POST is approximately three minutes.  
POST can be omitted for subsequent reboots by using the fastboot command. For  
more information about this command, refer to the latest version of the Fabric OS  
command reference guide. If you suspect a problem with the switch, enable POST to  
obtain more information on any failure.  
POST  
The success/failure results of the diagnostic tests that run during POST can be monitored  
through the error log or the command line interface.  
POST includes the following steps:  
•
•
•
•
Preliminary POST diagnostics are run.  
Operating system is initialized.  
Hardware is initialized.  
Diagnostic tests are run on several functions, including circuitry, port functionality,  
memory, statistics counters, and serialization.  
Boot  
Boot completes in approximately three minutes if POST is run. Boot includes the following  
tasks after POST completes:  
•
•
•
Universal port configuration  
Links initialized  
Fabric is analyzed; if any ports are connected to other switches, the 4Gb SAN  
Switch participates in a fabric configuration

The 4Gb SAN Switch obtains a domain ID and assigns port addresses  
Unicast routing tables constructed  
Normal port operation enabled  
Interpreting POST results  
To determine whether POST completed successfully and whether any errors were  
detected:  
1. Verify that the 4Gb SAN Switch LEDs indicate all components are healthy. See  
Table 13 for description and interpretation of LED patterns. If one or more LEDs do  
not display a Healthy state, use the switchshow command to verify that the LEDs  
on the switch are not set to “beacon”.  
2. Verify that the 4Gb SAN Switch prompt appears on the terminal of a computer  
workstation connected to the switch. If there is no switch prompt when POST  
completes, press Enter. If the switch prompt still does not appear, try opening  
another telnet session or another management tool. If this is not successful, the 4Gb  
SAN Switch did not successfully complete POST; contact HP.  
3. Review the switch system log for errors. Any errors detected during POST are written  
to the system log, accessible through the errshow command.  
For information about all referenced commands and accessing the error log, refer  
to the latest version of the HP StorageWorks Fabric OS administrator guide. For  
information about error messages, refer to the Fabric OS system error messages  
reference manual.

How to prevent electrostatic discharge  
Grounding methods  
How to prevent electrostatic discharge  
To prevent damage to the system, you must follow certain precautions 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, observe the following precautions:  
•
•
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  
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 static-dissipating floor  
mats.  
•
•
Use conductive field service tools.  
Use a portable field service kit with a folding static-dissipating work mat.
