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.

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
.
• 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.
