About this Guide

Port Interface Cards (PICs) are a cost effective and flexible mechanism for adding new or additional network interfaces to your switch or router.

This Installation and Safety Guide describes how to install the following PICs:

■AT-AR020 PRI E1/T1, a single ISDN Primary Rate E1/T1 interface

■AT-AR021(S) BRI-S/T, a single ISDN Basic Rate S/T interface

■AT-AR021(U) BRI-U, a single ISDN Basic Rate U interface

■AT-AR022 ETH, a dual Ethernet 10BASE-T/AUI port

■AT-AR023 SYN, a single 2Mbps synchronous interface

■AT-AR024 ASYN4, four asynchronous ports

■AT-AR026 4ETH, four Ethernet 10BASE-T ports

■AT-AR027 VoIP-FXS, two Foreign Exchange Voice over IP ports

Compatible Switches and Routers

You can install a PIC into a PIC bay on the base unit of your switch or router, or into a PIC bay on an AT-AR040 NSM (Network Service Module) installed in your switch or router.

The following table shows which PICs are appropriate for different expansion bays and models of switch and router.

This expansion bay ...	Accepts ...
PIC bays in the AR415S, AR440S, AR441S,	All PICs.
AR442S, AR725, and AR745 router
PIC bays in the AR750S, AR750S-DP, and	AT-AR020, AT-AR021, AT-AR023,
AR770S router	and AT-AR024.
AT-AR040 NSM in the AR745 router,	All PICs except AT-AR022 and
Rapier 16fi and Rapier 24i switch	AT-AR026.
AT-AR040 NSM in the Rapier 48w switch	AT-AR020, AT-AR021, and AT-AR024.

The AT-AR021(S) V3 hardware revision, identified by the label “AR021v3” on the board, requires a switch or router running AlliedWare® Operating System version 2.9.1-13 or later.
