Disconnect the switch or router from its AC or DC power supply

When using the Standard Installation method, be sure to disconnect the main

power supply and the redundant power supply before installing a PIC.

Installing a PIC with the switch or router powered ON can damage the PIC.

Remove the PIC-bay face-plate, NSM PIC-bay face-plate, or existing PIC

Loosen the thumbscrews to remove the face-plate or PIC.

Keep the face-plate for future use. If you remove the PIC, replace the face-plate to prevent

dust and debris from entering the switch or router and to maintain proper airflow.

Unpack the PIC

In an antistatic environment, remove the PIC from its packing material. Be

sure to observe ESD precautions.

Do not attempt to install a PIC or any other expansion option without

observing correct antistatic procedures. Failure to do so may damage the switch

or router, PIC, or expansion option. If you are unsure what the correct

procedures are, contact your authorised Allied Telesyn distributor or reseller.

If the PIC has jumpers, check they are correctly set

AT-AR020 PRI E1/T1 and AT-AR021(S) BRI-S/T PICs have user-

configurable jumpers. Check all jumpers and other hardware

configurations are set correctly on the new PIC (see Table 1 and Table 2).

AT-AR026 4ETH PICs have user-configurable links that set features such as

auto-negotiation, buffer size, and MAC address aging. Descriptions of the

links can be found in the PIC Hardware Reference.

Earlier versions of the AT-AR020 PIC also have a J3 interface jumper. If present, this

jumper must be installed for E1 mode and removed for T1 mode.
