12 280-Watt AC-Input Power Supply Replacement Instructions

Removing and Replacing the AC-Input Power Supply

• All network interface cables are connected to the port adapters.

• A Flash memory card is installed in its PCMCIA slot (if present).

• Each AC-input power cable is connected and secured with the cable-retention clip.

• The console terminal is turned on.

Step 2 At the rear of the router, place the power switch on the power supply in the ON (|)

position. Repeat this step if a second power supply is installed in the router. The green

OK LED on the power supply turns on.

Step 3 Listen for the fans; you should immediately hear them operating.

Step 4 During the boot process, observe the system’s LEDs. The LEDs on most of the port

adapters go on and off in irregular sequence. Some may go on, go out, and go on again

for a short time. On the I/O controller, the IO power OK LED comes on immediately.

Step 5 Observe the initialization process. When the system boot is complete (a few seconds), the

network processing engine begins to initialize the port adapters and the I/O controller.

During this initialization, the LEDs on each port adapter behave differently (most ﬂash

on and off). The enabled LED on each port adapter goes on when initialization is

completed, and the console screen displays a script and system banner similar to the

following:
