If the Port Bypass LEDs are blinking at a constant rate and the POST Fault LED is On, the switch detected a
fault during the POST. When a POST detects a fault, contact your authorized service representative.
Reading the switch LEDs
The Fibre Channel switch contains both system LEDs and port LEDs. The system LEDs indicate the status
of the switch, and the port LEDs provide status of a specific port. Figure 43 shows the Fibre Channel
switch with the system and port LEDs.

System LED Description
Power A green LED. When lit, this LED indicates that the switch is plugged in and the
internal power is functional.
Loop Operational A green LED. When lit, this LED indicates that the Fibre Channel loop has
completed initialization and is now operational.
POST Fault An amber LED. When lit, this LED indicates that the internal hardware self-test
failed and the switch will not function.
Over Temp An amber LED. When lit, this LED indicates that the ambient temperature has
exceeded 45 °C. The switch is still functional; however you should correct
the problem immediately. The Over Temp LED turns off when the problem
is corrected.
Table 24 describes the port LEDs.
