Replacement Procedures

Verifying and Troubleshooting the Installation

To verify that the blower assembly is properly installed and operational, complete the following steps:

Step 1 Listen to verify that the fans are operative. In noisy environments, you may want to place your hand to

the rear of the blower assembly and feel for airflow from the exhaust vent.

Step 2 Verify that the green power LED on the blower assembly front panel lights.

• If the power LED remains off, verify that the blower assembly is fully installed in the dial shelf, the

connector is firmly connected to the backplane, and the captive screws are adequately tightened.

Step 3 Verify that the yellow fault LED on the blower assembly front panel remains off.

• If the fault LED lights, the newly installed blower assembly may be faulty, or the chassis connector

may be damaged. Shut OFF system power; remove the blower assembly from the dial shelf, and

check the connectors. If the connectors are in good condition, reinstall the blower assembly in the

dial shelf and power ON the system.

• If the fault LED is still on, assume that the blower assembly is faulty. Install another blower

assembly and return the faulty blower assembly to the factory.

Replacing a Dial-Shelf Interconnect Port Adapter

The Cisco AS5800 is equipped with a dial-shelf interconnect port adapter that provides the connection

between the Cisco 7206 router shelf and the Cisco 5814 dial shelf. The interconnect port adapter installs

in the router shelf and connects to the dial shelf via a full-duplex 100-Mbps interconnect cable. No

installation tools are necessary; the dial-shelf interconnect port adapter connects directly to the router

midplane and locks into position by a port adapter lever. The dial-shelf interconnect port adapter has no

configurable ports.

The Cisco 7206 router shelf supports OIR; however, unless you have installed a second dial-shelf

interconnect port adapter and established a redundant connection to the dial shelf, you must either reload

the system software after removing and replacing a dial-shelf interconnect port adapter in an operating

system, or you must power off the system during the replacement procedure.

You reload the system software at the router-shelf console using the reload command. For a detailed

description of the reload command, refer to the configuration fundamentals command reference for your

Cisco IOS release.

Note When you reload the software, all active calls are lost. New incoming calls are not accepted

during the reload process.

If you power OFF and restart the system, the system software automatically reboots. For instructions on

powering OFF and powering ON the access server, refer to the Cisco AS5800 Access Server Hardware

Installation Guide, available online at
