You can download the complete document set for PICs, and for your switch or
router, from www.alliedtelesis.com/support/software. For more information
about the document set and other resources, see “Obtaining Documentation
and Resources” on page 46.
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 or AT-AR040-B 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.
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.
