Installation and Safety Guide

AT-AR026 4ETH PICs have user-configurable links that set features such as auto-negotiation, buffer size, and MAC address aging. For a detailed description of the links, see the Port 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-attach the 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 the show 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 2.9.1-13 or later.

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