LED Indicators
The tables below list all the LED indicators for all switch modules and include illustrations of the
different LED indicators as they appear on the front panel. All switch modules, including CPU modules,
have LED indicators for Power and Hot Swap & Card Status useful when hot swapping the module.

Per Port GBIC
Lights green to indicate a link for the port. Blinks green when there is activity
on the port.
Mgmt
Lights steady green if there is a link on the Mgmt port. Blinks green when
there is activity on the port. Remains dark when there is no link.
Fan Fail*
Steady amber light indicates one or more fans not functioning.
This does not light when the fans are functioning normally.
A fan failure will also trigger the system buzzer (alarm).
Master
Lights steady green when module is performing as active primary master.
System Status
Steady green light indicates normal system function.
Amber light indicates abnormal function. Abnormal function can include RPS
failure, fan failure or temperature problem. Any of these problems will also
trigger an audible alarm, the system buzzer.
Utilization**
Eight scales are used, 1%, 5%, 10%, 20%, 30%, 50%, 70%, 90%+ to indicate
traffic rate to the CPU.
Hot Swap &
Card Status
This will begin to blink amber when a hot swap of the unit has been initiated. It
should begin blinking immediately after the Hot Swap button has been
pushed. After a few seconds the module will be powered off and it may be
safely removed. Please read the instructions for hot swap removal and
insertion of DES-7000 Series modules for a complete description.
Power
Steady green light indicates normal voltage status the module.
Amber light indicates a voltage problem in this module.

*Please see the page 26 for more detailed
information about the system fans and the shutdown
sequence associated with fan failure.
**Utilization rates can be approximated to the number
of packets per second using the table to the right.
The indicators remain dark if there is no traffic.
