Cisco Catalyst 4000 Access Gateway Module Installation and Configuration Note

OL-3008-01

Chapter 2 Installing the Access Gateway Module

Checking the AGM Operation

The system runs diagnostic tests on any new interfaces.

• If the test passes, the system is operating normally. If the new AGM is faulty, the system resumes

normal operation but places the new module in the “faulty” state.

• If the test fails, the system crashes, which usually indicates that the new AGM has a problem and

should be removed.

Caution To avoid erroneous failure messages, allow at least 2 minutes for the system to reinitialize, and note

the current configuration of all interfaces before you remove or insert another AGM.

When you hot swap an AGM, the system displays status messages on the console. The following

example shows the messages logged by the system when a gateway module is removed from slot 3:

Console> (enable)

1999 Sep 09 12:23:26 %SYS-5-MOD_REMOVE:Module 3 has been removed

Console> (enable)

1999 Sep 09 12:23:44 %SYS-5-MOD_INSERT:Module 3 has been inserted

Console> (enable)

1999 Sep 09 12:23:47 %SYS-5-MOD_OK:Module 3 is online

Console> (enable)

If you use the show mod command to query the module before reinstalling a module to replace the

removed one, the system responds, “Module 3 is not installed.” When the module is reinserted, the

system recognizes the module as ready again.

Note Running the show mod command can take a few minutes.

Checking the AGM Operation

The AGM can take up to two minutes to boot and it does not appear on the supervisor engine console

until IOS is operating. The latter might take up to 10 minutes.

To check the status of the module, perform these steps:

Step 1 Ensure that the LED labeled STATUS is green (indicating the module is operational).

Step 2 When the switch is online, enter the show module command. Verify that the system acknowledges the

new module and that the status of the module is good.

Step 3 If the module is not operational, reseat it. If the module is still not operational, contact your customer

service representative.

Installing Voice and WAN Interface Modules

The AGM has four slots reserved for WAN interface modules (WICs), voice interface modules (VICs),

and T1/E1 multiflex voice/WAN interface modules (VWICs). You can install any combination of VICs,

WICs, and VWICs in slots 1 and 2, but slot 3 accepts only VICs and VWICs. Slot 4 is filled with the

high-density analog module when you first receive the switch.
