4. 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).
5. 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.
6. 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.
7. Return the NSM bay to use
Press the recessed Hot Swap button. The Swap LED will go out and the
In Use LED will light.
If the In Use LED lights only briefly and the Swap LED then lights
continuously, the NSM is of a type the software release does not support.
8. Verify the installation
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 4 and 5.
If the reinstallation fails, use the Standard Installation Method or see the
Network Service Module Hardware Reference, which has further
troubleshooting information.

10 for information about related LEDs found on the base-unit switch or router.
