switch module LEDs:
Link and Mode LEDs
for each port
Switch Chassis LEDs
Installing the Series 4100gl
Switches
When the switch is powered on, it performs its diagnostic self test. The entire
download, initialization, and self test process can take up to 2 1/2 minutes for
a fully loaded chassis, depending on the number and type of modules installed
in the switch.
LED Behavior:
During the self test:
■
Initially,
Power
and
Fault
, and all the switch chassis LEDs are on. Then,
after approximately 30 seconds, the
Fault
LED goes off.
■
After another approximately 5 seconds, the chassis LEDs go off except
Power
,
Self Test
,
Fan Status
, and
Power Status
, and
Module Status
. At the
same time, all the module LEDs go on as the modules receive power and
are downloaded with code.
■
After another approximately 20 seconds, when the download of code to
the modules is completed, the module LEDs go off. You may see each port
Link LED flash briefly, in sequence, as the ports are tested.
■
For the duration of the self test, the
Self Test
LED stays on.
When the self test completes successfully:
■
The
Power
LED stays on, and the Status LEDs on the switch chassis stay
on for the devices installed: one for each switch module installed, one for
each power supply installed, and one for all the fans.
■
The
Fault
and
Self Test
LEDs are off.
