Installing a Network Service Module
Warning Failure to follow this procedure when hot swapping an NSM will cause the
switch or router to crash, and may damage it and any files stored in Flash.
1. Read the safety information.
See the Installation and Safety Guide for your switch or router. A copy of this
guide can be found on the CD-ROM that came with your switch or router, or at
www.alliedtelesis.co.uk/site/products/
2. If you are not hot swapping, remove power to the switch or router.
Warning Be sure to disconnect the main power supply and the redundant
power supply before installing the NSM. Installing an NSM with the switch or
router powered ON can damage the NSM or base unit.
If you are hot swapping, prepare the NSM bay.
Warning 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 licenses and other files
may be damaged.
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 nor Swap LED are lit, the
software release does not support hot swapping, and you must install the NSM
with the switch or router powered OFF.
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 (see the following figure).
