AT-CV1203 Chassis Installation Guide

Verifying the Installation

After powering on the chassis, view the PWR GOOD LED. The LED

should be ON. The PWR A and PWR B LEDs should also be ON for DC

connectors that are connected to power adapters. If an LED is OFF,

perform the following:

 Verify that the power cord is firmly connected to the AC power source

and to the power adapter.

 Verify that the power adapter is firmly connected to a DC connector on

the back panel of the chassis.

 Verify that the power source is operating properly by plugging a

different device into it.

 Try connecting the power adapter to another power source, preferably

located on a different circuit.

 Try using a different power adapter and power cord.

 Check that the voltage from the power source is within the required

levels for your region.

For instructions on how to troubleshoot a problem with a line card, refer to

the documentation that ships with the card.
