To hot swap an NSM:
1.
Prepare the NSM bay for hot swap
If the In Use LED (next to the NSM bay) is lit, use a pencil tip or similar
object to press the recessed Hot Swap button. The In Use LED should go
out and the Swap LED should light.
If the In Use LED remains lit, or if neither the In Use or Swap LED are lit,
the software release does not support hot swapping, and the Standard
Installation Method must be used to install or remove the NSM.
Do not attempt to hot swap while the contents of Flash are being modified; for
instance, during Flash compaction or when files are being loaded onto the
switch or router. If the switch or router crashes while Flash is being modified,
configuration files, software release files, feature licences and other files may be
damaged.
2.
Prepare the NSM
In an antistatic environment, remove the NSM from its packing material.
Be sure to observe ESD precautions.
Do not attempt to install an NSM without observing correct antistatic
procedures. Failure to do so may damage the switch, router, or NSM. If you are
unsure what the ‘correct’ procedures are, contact your authorised Allied Telesyn
distributor or reseller.
3.
Remove the switch or router NSM-bay face-plate or existing NSM
If the switch or router does not have an NSM installed, remove the blank
NSM-bay face-plate by loosening the two M4 Phillips screws.
If an NSM is already installed, disconnect its network cables and TNV lines
before removing it from the switch or router.
Remove the NSM by unscrewing both thumbscrews at the same time. As
the thumbscrews are turned, they will push the NSM out of the bay.
If the NSM has extractor levers, moving them to the open position will
assist the removal process.
When removing an NSM, take care to turn each thumbscrew by an equal
amount to ensure that the NSM does not become misaligned. Forcing a jammed
thumbscrew may damage the NSM card.
If a thumbscrew becomes tight, it must not be forced. Instead, screw it in or
out slightly to loosen it and then try again, taking care to unscrew both
thumbscrews at the same rate.
Keep the face-plate for future use. If you remove an NSM, replace the face-plate to
prevent dust and debris from entering the switch or router and to maintain proper
airflow.
4.
Slide the NSM into place
Slide the NSM into the NSM bay, making sure that 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.
