Installation and safety considerations  
The 8Gb SAN Switch installs in the I/O bays in the rear of the HP BladeSystem c-Class enclosure. Refer to  
the appropriate BladeSystem Enclosure Setup and Installation Guide for specific enclosure requirements.  
Installing multiple switches  
If you do not have a DHCP server connected to the OA, install and configure one 8Gb 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 on this switch. In cases where DHCP is available, IP address conflicts will not  
occur, simplifying multiple switch installations. See Using external DHCP, page 24.  
Each switch must be assigned a unique Ethernet IP address during configuration. Once the default  
Ethernet IP address on the 8Gb SAN Switch has been changed, you may install additional 8Gb 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 8Gb 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 8Gb SAN Switch must be inserted into any ports where SFPs are  
not installed, to help contain air flow in the BladeSystem chassis.  
Install the 8Gb SAN Switch  
Install the Brocade 8Gb SAN Switch into the enclosure:  
1. Locate the appropriate interconnect bay in the rear of the enclosure as specified in the appropriate  
HP BladeSystem Enclosure Setup and Installation Guide provided with your enclosure.  
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:  
All panels and doors should be in place and securely fastened while the unit is in operation, for proper  
cooling and for EMI emissions control.  
OA power verification  
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 with the OA web interface. Refer to  
the HP BladeSystem Onboard Administrator User Guide.  
Check LEDs  
See Figure 6 to locate power-on LEDs. Verify that the LEDs match the indicators described in Table 10.

2. Issue portdisable portnumber where portnumber is the port number of the port you  
want to disable.  
Using Dynamic Ports On Demand (DPOD)  
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, page 28.  
IMPORTANT:  
For the Brocade 8Gb 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.

Maintaining the 8Gb SAN Switch  
The 8Gb SAN Switch does not require any regular physical maintenance.  
However, it is critical that environmental conditions, described in Environmental requirements, page 50,  
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 8Gb SAN Switch shipping carton (see Figure 1) must be inserted in  
ports where SFPs are not installed. Installing dust covers ensures proper air flow 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.  
To install a replacement SFP:  
1. Make sure that the bail is in the unlocked position.

Diagnostic tests  
In addition to POST, Fabric OS 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 with 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, enter diagHelp.  
All diagnostic tests are run at link speeds of 1 Gbps, 2 Gbps, 4 Gbps, and 8 Gbps.  
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 enter help followed by the name of the diagnostic test.  
Powering on and off  
8Gb SAN Switch power is provided by the enclosure. The 8Gb SAN Switch runs 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 8Gb SAN Switch from the enclosure interconnect bay.

NOTE:  
Each time the 8Gb 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 8Gb 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  
15 , page 35 for details about LED activity.  
LED indicators  
All 8Gb SAN Switch LEDs are located on the port side. See Figure 8 and Table 14.

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 8Gb 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  
Boot  
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 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 8Gb SAN Switch participates  
in a fabric configuration  
•
•
•
The 8Gb 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 8Gb SAN Switch LEDs indicate all components are healthy. See Table 16, page 35  
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”.  
36

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.  
If you do not have any of the suggested equipment for proper grounding, have an HP authorized  
reseller install the part.  
NOTE:  
For more information on static electricity, or for assistance with product installation, contact your  
HP authorized reseller.
