CPU Module

The CPU module, displayed in Figure 13, is at the top of the chassis. This is the only slot it will work in. If it is not at the top of the chassis, the DES-5200 will not work. See Table 6: CPU Module LEDs for an explanation of the LEDs on the CPU module.

Each LED is explained in detail.

Power

The power LED lights when the DES-5200 is powered on. The purpose is to confirm that the DES-5200 is getting adequate power. See Table 5: Power LED.

Table 5: Power LED

Status	Color	Meaning
On	Green	DES-5200 is powered on
Off	Dark	DES-5200 is powered off, check power cable and
		connection
Status

The Status LED indicates the status of a firmware download. The LED will increment from left to right while firmware is being downloaded. It will be dark during normal operation.

Diagnostic

The Diagnostic LED is used to diagnose any problems on the DES-5200. If any part of the DES-5200 fails the POST or if a problem occurs the Diagnostic LED displays a code indicating the problem. See Chapter 6 for the meaning of the LED code and a recommended action.

Utilization

The Utilization LED indicates the utilization of the DES-5200’s CPU. It increments from left to right. The higher the number the greater the utilization.
