Guidelines and limits for installing PICs

Observe the following guidelines and limits when installing PICs:

Use the PIC bays on the switch or router first, before installing PICs into an AT-AR040 NSM.

Fill any PIC bays in the base router starting at bay 0.

Fill the PIC bays in the AT-AR040 NSM starting at bay 0.

You can install a maximum of two AT-AR020 PRI E1/T1 PICs into an AT-AR040 NSM, and maximum of four total in a switch or router.

If two AT-AR020 PICs are installed in an AT-AR040 NSM, PIC one must be installed in the lower row (bay 0 or 1) and the other PIC must be installed in the upper row (bay 2 or 3).
