The nonport side of the switch has one LED per power supply/fan assembly. See

Figure 17 (page

. The standard configuration of the HP SN3000B 16Gb FC Switch includes a single power

supply/fan assembly.

Table 6 (page 37)

POST and boot specifications

When the switch is powered on or rebooted, it performs POST. Total boot time with POST can be
several minutes. POST can be omitted after subsequent reboots by using the

fastboot

command

or entering the

diagDisablePost

command to persistently disable POST. For more information

about these commands, see the Fabric OS 7.0.x Command Reference Manual.

POST

You can monitor the results of the diagnostic tests that run during POST through LED activity, the
error log, or the CLI. POST includes the following tasks:

Conducting preliminary POST diagnostics

Initializing the operating system

Initializing hardware

Running diagnostic tests on several functions, including circuitry, port functionality, memory,
statistics counters, and serialization

To determine whether POST completed successfully:
1.

Inspect the switch LEDs to determine whether components are operating properly.

See

Table 5 (page 36)

and

Table 6 (page 37)

for descriptions of LED patterns. If one or more

LEDs do not display a healthy state, verify that the LEDs are not set to beacon by entering the

switchshow

command to detect if beaconing is active.
