Power-on self test (POST)
When you power on the Fibre Channel switch, it performs a Power–on Self Test (POST) to verify that
the switch is functioning properly. During a POST, all of the indicators turn on for approximately two
seconds. Then, turn off all of the indicators, except the power indicator.
If the Port Bypass indicators are blinking at a constant rate and the POST Fault indicator is on, the
switch detected a fault during the POST. In this case, you need to contact your HP authorized service
representative.
Reading the switch indicators
The Fibre Channel switch contains both system indicators and port indicators. The system indicators
indicate the status of the switch, and the port indicators provide status of a specific port. Figure 21 shows
the Fibre Channel switch with the system and port indicators.
Table 19 lists and describes the system indicators.
