If you are inserting the bottom NSM module, and if the bottom rail is obstructing access
to the latching mechanisms, place your index fingers through the finger holes from the
inside (by crossing your arms).
e. With your thumbs, press down and hold the orange tabs on top of the latching mechanisms.
f. Gently push forward to get the latches over the stop.
g. Release your thumbs from the tops of the latching mechanisms, and then continue pushing until the
latching mechanisms snap into place.
The NSM module should be fully inserted into the shelf and flush with the edges of the shelf.
9. Reconnect the cabling to the NSM module:
a. Reconnect the storage cabling to the same two NSM module ports.
Cables are inserted with the connector pull-tab facing up. When a cable is inserted correctly, it clicks
into place.
b. Reconnect the power cord to the power supply, and then secure the power cord with the power cord
retainer.
When functioning correctly, a power supply’s bicolored LED illuminates green.
Additionally, both NSM module port LNK (green) LEDs illuminate. If a LNK LED does not illuminate,
reseat the cable.
10. Verify that the attention (amber) LEDs on the NSM module containing the failed boot media and the shelf
operator display panel are no longer illuminated.
It can take between 5 to 10 minutes for the attention LEDs to turn off. This is the amount of time it takes the
NSM module to reboot and the boot media image copy to complete.
If the fault LEDs remain on, the boot media might not be seated correctly or there might be another issue
and you should contact technical support for assistance.
11. Verify that the NSM module is cabled correctly, by running Active IQ Config Advisor.
If any cabling errors are generated, follow the corrective actions provided.

Replace a DIMM - NS224 shelves
You can replace a faulty DIMM nondisruptively in an NS224 drive shelf that is powered
on, and while I/O is in progress.
Before you begin
• The shelf’s partner NSM module must be up and running, and be cabled correctly so that your shelf
maintains connectivity when you remove the NSM module with the failed FRU (target NSM module).
