FC Port Diagnostics
Port diagnostics for each port are indicated by the Logged-In LED. The Logged-In
LED is the top LED of the pair to the right of each port on an I/O blade. For
example, Figure 4-3 identifies the Logged-In LEDs for first four ports on an I/O
blade.
Figure 4-3 Logged-In LED
The Logged-In LED has three indications:
Continuous illumination: A device is logged in to the port.
Flashing once per second: The port is busy, or the port is in the diagnostics
state.
Flashing twice per second: The port is down, offline, or an error has
occurred. This does not apply to a port that fails a diagnostic test.
If a Logged-In LED shows an error indication, review the event browser for alarm
messages regarding the affected port. You can also inspect the event log using
the Show Alarm command. Pertinent alarm messages will point to one or more of
the following conditions:
