HP B-series 16Gb FC Switches Hardware Reference Guide

• Analyzing the fabric.
If any ports are connected to other switches, the switch participates in a fabric configuration.
• Obtaining a domain ID and assigning port addresses.
• Constructing unicast routing tables.
• Enabling normal port operation.
Switch maintenance
The switch supports only HP-branded 8 Gb/s and 16 Gb/s SFP+ optical transceivers. For the FC
connections, the switch uses SFP+ transceivers that support any combination of SWL, LWL, and
ELWL optical media.
If you use an unqualified transceiver, the switchshow command output shows the port in a
Mod_Inv state. Fabric OS also logs the issue in the system error log.
For information about installing transceivers, see “Connecting devices” (page 41).
Diagnostic tests
In addition to POST, Fabric OS includes diagnostic tests to help you troubleshoot the hardware
and firmware. This includes tests of internal connections and circuitry, fixed media, and transceivers
and cables.
The tests are implemented by command through a Telnet session or a console set up to the serial
connection to the switch. Some tests require that ports be connected by external cables in order
to verify the serializer/deserializer interface, transceiver, and cable. Some tests require loopback
plugs.
Diagnostic tests run at a link speed of 2, 4, 8, 10, or 16 Gb/s (FC), depending on the speed of
the link being tested and the type of port.
NOTE:
• Diagnostic tests can temporarily lock the transmit and receive speed of the links.
• HP does not support 2 Gb/s connectivity to the HP StoreFabric SN6500B, SN6000B, and
SN3000B 16Gb FC switches.
For information about specific diagnostic tests, see the Fabric OS Troubleshooting and Diagnostics
Guide.
Switch management
You can use the management functions built into the switch to monitor the fabric topology, port
status, physical status, and other information to help you analyze switch performance and to
accelerate system debugging.
For information about upgrading the Fabric OS version installed on your switch, see the Fabric
OS Administrator’s Guide.
You can manage the switch using any of the management tools listed in Table 11 (page 53). See
the Fabric OS 7.0.x Command Reference Manual for more information on the CLI commands.
