NSMs slot into a base-unit switch and either directly provide additional

interfaces, or provide multiple slots where additional interfaces can be added.

The following NSMs are available:

■ AT-AR040 (4 Port Interface Card (PIC) slots)

■ AT-AR041 (8 BRI S/T WAN Ports)

■ AT-AR042 (4 BRI S/T WAN Ports)

■ AT-AR048 (1 unchannelised DS3 port)

1. The AT-AR048 can be used only in Rapier 24i models whose serial number

ends in J or higher (N or higher for maximum performance). A label with the

serial number can be found on the underside of the switch.

For more information on NSMs, contact your Authorised Allied Telesis

distributor or reseller, or see the Network Service Module Hardware Reference.

This and other documentation can be found on the CD-ROM bundled with

your switch, or at www.alliedtelesis.com/support/software.

Port Interface Cards (PICs)

PICs provide a cost effective and flexible mechanism for adding new or

additional WAN network interfaces to the switch. By adding or changing PICs,

the switch’s network interface capabilities can be upgraded without replacing

the switch itself. A PIC can provide additional network interfaces, or can be

replaced with a different PIC to provide alternative interface types.

An AT-AR040 NSM must be installed before PICs can be used with Rapier

Switches.

The following PICs can be used in the AT-AR040 NSM when it is installed in a

Rapier switch (with a maximum of two E1/T1/PRI cards):

• AT-AR020 PRI E1/T1

• AT-AR021 (S) BRI- S/T*

• AT-AR021 (U) BRI-U*

• AT-AR023 SYN*

• AT-AR024 ASYN4

• AT-AR027 VoIP-FXS

* These PICs can be hot swapped if the host Rapier is running Software Version

2.3.1 or later. See the Port Interface Card Hardware Reference for more

information.

We recommend that AT-AR022 ETH PICs and AT-AR026 4ETH PICs not be

used in the NSM PIC bays because performance of these interfaces is likely to

be reduced and packet loss may occur.

For more information on PICs, contact your Authorised Allied Telesis

distributor or reseller, or see the Port Interface Card Hardware Reference. This and
