100 AR Router
Testing a PAC
There are several ways to check that the PAC is installed and operating
correctly. First, check that the router has recognised the card. Turn on the router
and enter the command:
SHOW SYSTEM
to display system information (Figure 58 on page 96).
The first part of the display shows details of the cards installed in the router.
There should be at least two entries, one for the router base card and one for
the PAC. Both the serial number and the part name should be displayed.
If there is no entry for the PAC then the router's boot process has not correctly
detected the PAC's presence. The most likely cause is that the PAC is not
correctly plugged into the slot on the router's base board. Repeat the
installation process, paying particular attention to Step 6.
Use the SHOW SYSTEM command again, and if the display is still not correct,
contact your authorised Allied Telesyn distributor or reseller.
If you have any difficulty with the PAC at any time, contact your authorised Allied
Telesyn distributor or reseller and quote the serial numbers of both the base card on the
router and the PAC. The serial numbers and revision details can be read using the
SHOW SYSTEM command. It's a good idea to record this information for later
reference.
