6. Slide the NSM into place
Slide the NSM into the NSM bay, making sure the ends of the thumbscrews
are aligned with the screw holes on the switch or router.
If the NSM has extractor levers, they should be in the closed position
(Figure 2 on page 5).
7. Secure the NSM
When the NSM has been firmly pushed into place, turn the NSM’s two
thumbscrews to engage their threads. Tighten both thumbscrews at the
same rate to pull the NSM into position.
The screws will tighten when the NSM panel is in its installed position. The
thumbscrews should be firm but not over-tight.
If one thumbscrew becomes tight before the other, loosen it slightly before
proceeding.
8. Installing PICs in the AT-AR040 NSM
If you have PICs to install, install them now by following the Port Interface
Card Quick Install Guide. If there are more PIC bays than PICs, use the bays
on the switch or router base unit first, then fill the NSM PIC bays starting
with bay 0.
9. Apply power to the switch or router by re-attaching the power cord
Check that the switch or router power LED lights green.
10. If you disconnected a redundant power supply, reconnect it
11. Verify the installation
Check the In Use LED. The In Use LED (on the switch or router rear panel)
lights to indicate the NSM is installed, is receiving power, and is
operational.
Use the show system command to verify the switch or router has
recognised the NSM. If there is no NSM entry in the output, recognition
has failed.
If the In Use LED fails to light or recognition fails, repeat the installation
process, paying particular attention to steps 6 and 7.
If the reinstallation fails, see the Network Service Module Hardware Reference,
which has further troubleshooting information.
Hot Swap Installation Method (for Software Version 2.3.1 or later):
WARNING: Failure to follow this procedure when hot swapping an NSM will
cause the switch or router to crash, and may damage the switch or router and
files stored in Flash.
The AT-AR040 NSM can be hot swapped with PICs installed in its PIC bays. There is
no need to remove the PICs before hot swapping. See the NSM Hardware Reference for
information on the operational characteristics of hot swapped interfaces.
