•HP Read Me First document
•HP End User License Agreement letter
Installation and safety considerations
The 16Gb SAN Switch installs in the I/O bays in the rear of the HP BladeSystem c-Class enclosure.
See 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 16Gb 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 do not occur, simplifying multiple switch installations. See “Using external DHCP
” (page 14). See also the most current documentation for interconnects and other HP BladeSystem
c-Class components at the HP website: http://www.hp.com/go/bladesystem/interconnects.
Each switch must be assigned a unique Ethernet IP address during configuration. Once the default
Ethernet IP address on the 16Gb SAN Switch has been changed, you may install additional 16Gb
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 16Gb 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 16Gb SAN Switch must be inserted into any
ports where SFPs are not installed, to help contain air flow in the BladeSystem chassis.
Kit contents11
Installing the 16Gb SAN Switch

Other HP BladeSystem c7000 Enclosures have a maximum speed of 8 Gbps.
OA power verification
The 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.
See the HP BladeSystem Onboard Administrator User Guide for more information.
Verifying the configuration
The OA is the enclosure management module that supports and manages the HP BladeSystem
c-Class enclosure and all the devices used in the enclosure.
Once the switch is installed in the interconnect bay, the OA verifies that the switch type matches
the mezzanine cards present on the server blades. If there is no mismatch, the OA powers up the
switch.
If the switch does not power up, check the enclosure and switch status using the OA web interface.
See the HP BladeSystem Onboard Administrator User Guide for more information and
troubleshooting tips.

Using 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.
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 Page 18.
IMPORTANT:For the Brocade 16Gb 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 is not 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.

You can connect a management station to one switch with Ethernet while managing other switches
connected to the first switch with FC. To do so, set the FC gateway address of each of the other
switches to be managed to the FC IP address of the first switch.
The gateway address of the first switch should be set to whatever the gateway address is for the
subnet on which the first switch resides. See Table 7 (page 20).
Table 7 Connecting with a management station
Maintaining the 16Gb SAN Switch
The 16Gb SAN Switch does not require any regular physical maintenance.
It is critical, however, that environmental conditions, described in Environmental
requirements (page 33), 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 16Gb SAN Switch shipping carton (see Figure 1 (page 6)) must
be inserted in ports where SFPs are not installed. Installing dust covers ensures proper air flow and
helps reduce dust contamination.
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.
2.Orient the SFP with the appropriate port (see Figure 6 (page 21)).
Figure 6 Installing an SFP
3.Insert the SFP into the port until it clicks.
4.Close the bail.
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 or portcfgdport.
2. SFP1. Bail
Maintaining the 16Gb SAN Switch21
All diagnostic tests are run at link speeds of 2 Gbps, 4 Gbps, 8 Gbps, and 16 Gbps.
CAUTION:Diagnostic tests can temporarily lock the transmit/receive link speed during diagnostic
testing.
For information about specific diagnostic tests, see the latest version of the HP Fabric OSAdministrator Guide, or enter help followed by the name of the diagnostic test.
Powering on and off
The 16Gb SAN Switch power is provided by the enclosure. The 16Gb SAN Switch runs POST by
default each time power to the enclosure is turned on. The POST process can last up to three
minutes.
To remove power from the switch, remove the 16Gb SAN Switch from the enclosure interconnect
bay.
NOTE:Each time the 16Gb 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 the 16Gb 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 8 (page 22) for details about LED activity.
LED indicators
All 16Gb SAN Switch LEDs are located on the port side. See Figure 5 (page 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 16Gb 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, see the latest version of the Fabric OS Command ReferenceGuide. If you suspect a problem with the switch, enable POST to obtain more information on any
failure.
POST
The success and failure results of the diagnostic tests that run during POST can be monitored through
the error log or the CLI.
POST includes the following:
•Running preliminary POST diagnostics
•Initializing the operating system
•Initializing hardware
•Running diagnostic tests on several functions, including circuitry, port functionality, memory,
statistics counters, and serialization
Boot
Boot completes in approximately three minutes if it is run. Boot includes the following tasks after
POST completes:
•Universal ports are configured.
•Links are initialized.
•Fabric is analyzed; if any ports are connected to other switches, the 16Gb SAN Switch
participates in a fabric configuration.
•The 16Gb SAN Switch obtains a domain ID and assigns port addresses.
•Unicast routing tables are constructed.
•Normal port operation is enabled.
Interpreting POST results
To determine whether POST completed successfully and whether any errors were detected:
1.Verify that the 16Gb SAN Switch LEDs indicate that all components are healthy. See
Table 9 (page 23) for a 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 16Gb 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 the 16GB SAN Switch still does not complete POST successfully, contact your HP
representative.
24Managing the 16Gb SAN Switch
3.Any errors detected during POST are written to the system log. Use the errshow command
to review the system log.

B Electrostatic discharge and grounding recommendations
Electrostatic discharge recommendations
CAUTION: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 can
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 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 HP authorized reseller install
the part.
NOTE:For more information on static electricity, or for assistance with product installation,
contact your HP authorized reseller.
