CPU Module
The CPU module, displayed in
Figure 10
, is in the middle of the chassis. This is
the only slot it will work in. If it is not middle of the chassis, the DES-5600 will
not work. See Table 2: Power LED for an explanation of the LEDs on the CPU
module.
Each LED is explained in detail.

Power
The power LED lights when the DES-5600 is powered on. The purpose is to
confirm that the DES-5600 is getting adequate power. See Table 2: Power LED.

Green
DES-5600 is powered on

Status
The OK indicates the status of the switch. The OK LED is green when the switch
is okay. The Fault LED is amber if there is problem.
Utilization
The Utilization LED indicates the utilization of the DES-5600’s CPU. It
increments from left to right. The higher the number the greater the switch
utilization.
Module Fail
Indicates the number of the module that has failed.
