AT-AR024ASYN4, four asynchronous ports

AT-AR0264ETH, four Ethernet10BASE-Tports

AT-AR027VoIP-FXS,two Foreign Exchange Voice over IP ports

You can download the complete documentation for Port Interface Cards from www.alliedtelesis.com/support/software. For more information about the documentation and other resources, see“Obtaining Documentation and Resources” on page 11.

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-AR040NSM (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.

Choosing a PIC Bay

Observe the following guidelines when selecting a PIC bay:

Use the PIC bays on the switch or router base unit first, before installing PICs into an AT-AR040NSM.

Fill the PIC bays in an AT-AR040NSM starting at bay 0.

You can install a maximum of two AT-AR020PRI E1/T1 PICs into anAT-AR040NSM, and maximum of four total in a switch or router.

If two AT-AR020PICs are installed in anAT-AR040NSM, 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).

If an AT-AR020PIC is installed in anAT-AR040NSM, and operating in E1 mode, you can not install anAT-AR021(S)orAT-AR021(U)PIC in the same row of the NSM.

You can install a maximum of four AT-AR027PICs in an AR745 router fitted with anAT-AR040NSM.

Avoid installing an AT-AR022orAT-AR026PIC in anAT-AR040NSM. Performance of these interfaces may be reduced and packet loss may occur.

For instructions on installing an AT-AR040NSM into your switch or router, see the

Network Service Module Installation and Safety Guide supplied with the NSM. You can also download this document from www.alliedtelesis.com/support/software.

Installing a PIC

This section describes the procedure for installing a PIC. You should also follow this procedure, in particular the safety procedures and warnings, when replacing or removing a PIC.

Caution You cannot install PICs into anAT-AR040NSM that has power applied to it. This includes NSMs that have been deactivated using the hot swap button, but not physically removed from the switch or router. To ensure that all power is removed from the NSM bay, you must either physically remove it from the switch or router using the hot swap method, or disconnect all power sources to the switch or router.

1.Read the safety information.

For safety information, see the Installation and Safety Guide shipped with your switch or router. You can also download the complete documentation for your switch or router from www.alliedtelesis.com/support/software/.

2.Gather the tools and equipment you will need.

A medium-sizedflat-bladedscrewdriver may be useful when loosening the PIC thumbscrews. You should also have any cables required for connecting the PIC to a wide area network or other network devices.

3.Remove power to the switch or router.

Warning Do not install a PIC into an NSM bay or PIC bay base unit without first removing power from the switch or router. Be sure to disconnect both the main power supply and any attached redundant power supply. Installing a PIC with the switch or router powered ON can damage the PIC, NSM and base unit.

4.Remove all TNV connections to existing PICs.

Warning Remove any cables attached to the external WAN ports of theAT-AR020,AT-AR021andAT-AR027PICs, as these supply TNV into the switch or router. Dangerous voltages may be present on some parts of the board, even if the switch or router is powered OFF.

5.Install the AT-AR040NSM if required.

Use the installation instructions in the Network Service Module Installation and Safety Guide to install anAT-AR040NSM.

6.Remove the PIC bay faceplate, NSM PIC bay faceplate, or existing PIC.

Loosen the thumbscrews to remove the faceplate or PIC. Keep the faceplate for future use. If you remove the PIC, replace the faceplate to prevent dust and debris from entering the switch or router and to maintain proper airflow.

7.Unpack the PIC.

In an antistatic environment, remove the PIC from its packing material. Be sure to observe ESD precautions.

Warning 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 Telesis distributor or reseller.

8.If the PIC has jumpers, check they are correctly set.

Warning Do not attempt to change any jumpers, DIP switches, or other hardware configurations while the switch or router is connected to a power supply, redundant power supply, or a ‘live’ network. Dangerous voltages may be present on some parts of the board, even if the switch or router is turned off.

AT-AR020PRI E1/T1 andAT-AR021(S)BRI-S/TPICs haveuser-configurablejumpers. Check all jumpers are set correctly on the new PIC, as shown inTable 1 andTable 2. Early versions of theAT-AR020PIC also have a J3 interface jumper. If present, this jumper must be installed for E1 mode and removed for T1 mode. TheAT-AR021(S)V2 hardware revision, identified by the label “AR021 V2” on the board, supports both TE and NT mode. Jumper J4, when installed, selects NT mode. The PIC should be configured as a TE for normal operation.

AT-AR0264ETH PICs haveuser-configurablelinks that set features such asauto-negotiation,buffer size, and MAC address aging. For a detailed description of the links, see thePort Interface Card Hardware Reference.

For more information on PIC jumpers and hardware configurations, see the

Port Interface Card Hardware Reference. This document can be downloaded from www.alliedtelesis.com/support/software/.

9.Slide the PIC into place.

PIC bays should be filled in numerical order, starting with the lowest available bay (e.g., bay 0) followed by bays with progressively higher numbers.

Insert the PIC slowly, being sure to keep it straight. Press firmly until you feel the connector engage. Do not force a misaligned PIC.

10.Secure the PIC by tightening its thumbscrews.

11.Apply power to the switch or router.

Re-attachthe power cord, and reconnect any redundant power supply.

12.Test the PIC.

There are several ways to check the PIC is installed and functioning correctly.

The show system command displays general system information about PICs and any other hardware installed, as well as memory, software version and patches loaded on the switch or router.

If the PIC does not appear in the list of boards at the top of the show system output, then your switch or router has not recognised the PIC. Likely reasons are:

Your switch or router does not support the PIC. See “Compatible Switches and Routers” on page 3.

Your switch or router is running a version of the AlliedWare® Operating System that does not support the PIC. Use theshow system command to

check the software version. In particular, the AT-AR021(S)V3 hardware revision requires a switch or router running AlliedWare® Operating System

version 2.9.1-13or later.

The PIC is not installed correctly. Repeat the installation process, paying particular attention to step 9.

For more detailed information on testing PICs, see the Port Interface Card Hardware Reference. You can download this document fromwww.alliedtelesis.com/support/software/.
