ch installs in the I/O bays in the rear of the HP BladeSystem c-Class enclosure. Refer to

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,page24.

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 H P BladeSystem Enclosure Setup and Installation G uide 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:

• Theairventsontheenclosurearenotblockedorrestricted.

• 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
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 G uide 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).

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.

Using Dynamic Ports On Demand (DPOD)

DPOD functionality do es 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 cable d por ts

• Automatically enabling ports

• Automatically assigning port licenses

To initiate DPOD, use the licensePort command, as described in DPOD commands,page28.

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 in itial 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.

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 a nd
cables in use.

Initiate diagnostic tests with the comm a nd line, using a Telnet session or a terminal setup with a serial
connection to the switch. Some tests require the ports to be c onnected 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

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.

How to prevent electrostatic discharge

To prevent damage to the system, you must follow certain precautions when setting up the system or
handling par ts. 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 c

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

• Place parts on a grounded surface b efore removing them from their containers.

• Avoid touc

• Always make sure you are properly grounded when touching a static-sensitive component or

assembly.

hing pins, leads, or circuitry.

Grounding methods

There are several methods for grounding. Use one or m ore 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 g round, 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:

single mode The fiber optic cabling standard that corresponds to distances up to 10 km

between devices.

SNMP Simple Network Management Protocol. An Internet m anag em ent protocol that

uses either IP for network-level functions and UDP for transport functions, or
TCP/IP for both. SNMP can be made available over other protocols (such as
UDP/IP) because it does not rely on the underlying communication protocols.

See also ???, ???.

SNS Simple Name Server. A switch service that stores names, addresses, and

attributes for up to 15 minutes, and provides them as required to other devices in
thefabric. Mayalsobereferredtoasadirectory service.

switch Hardware that routes frames according to FC protocol and is controlled by

software.

switch port A port on a switch. Switch ports can be E_Ports, F_Ports, or FL_Ports.

SWL short-wavelength. A type of fiber optic cabling that is based on 850 mm lasers

and supports link speeds up to 2 Gb/s. May also refer to the type of transceiver.

tenancy The time span that begins when a port wins arbitration in a loop and ends when

the same port returns to the monitoring state. Also called loop tenancy.

throughput The rate of data flow achieved within a cable, link, or system. Usually measured

in bits per second (b/s) .

topology With respect to FC, the configuration of the FC network and the resulting

communication paths allowed. There are three possible topologies:

• Point-to-point: A direct link between two communication ports

• Switched fabric: Multiple N_Ports linked to a switch by F_Ports

• Arbitrated loop: Mu ltiple NL_Ports connected in a loop

transmission

A 10-bit character encoded according to the rules of the 8b/10b algorithm.

character

transmission word A group of transmission characters.

trap (SNMP) The message sent by an SNMP agent to inform the SNMP management station

of a critical error. See also ???.

U_Port Universal port. A switch port that can operate as a G_Port, E_Port, F_Port, or

FL_Port. A port is defined as a U_Port when it is not connected or has not yet
assumed a specificfunctioninthefabric. See also ???, ???, ???.
