About this task
• Allow at least 70 seconds between removal and installation of the NVMe shelf module (NSM).
This allows enough time for ONTAP to process the NSM removal event.
•
Best practice:
The best practice is to have current versions of NVMe shelf module (NSM) firmware and
drive firmware on your system before replacing FRU components.
Do not revert firmware to a version that does not support your shelf and its components.

• If needed, you can turn on the shelf’s location (blue) LEDs to aid in physically locating the affected shelf:
storage shelf location-led modify -shelf-name
shelf_name
-led-status on
If you do not know the
shelf_name
of the affected shelf, run the
storage shelf show
command.
A shelf has three location LEDs: one on the operator display panel and one on each NSM module.
Location LEDs remain illuminated for 30 minutes. You can turn them off by entering the same command,
but using the
off
option.
• When you unpack the replacement fan, save all packing materials for use when you return the failed fan.
If you need the RMA number or additional help with the replacement procedure, contact technical support

Replacing a fan in an NS224 drive shelf
Steps
1. Properly ground yourself.
2. Disconnect the cabling from the NSM module that contains the FRU that you are replacing:
a. Disconnect the power cord from the power supply by opening the power cord retainer, and then unplug
the power cord from the power supply.
Power supplies do not have a power switch.
b. Disconnect the storage cabling from the NSM module ports.
Make a note of the NSM module ports that each cable is connected to. You reconnect the cables to the
same ports when you reinsert the NSM module, later in this procedure.
3. Remove the NSM module from the shelf:
a. Loop your index fingers through the finger holes of the latching mechanisms on either side of the NSM
module.
