• Replacing the NSM module involves moving the DIMMs, fans and power supply from the impaired NSM
module to the replacement NSM module.
You do not move the real-time clock (RTC) battery or boot media. They come preinstalled in the
replacement NSM module.
• 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.

• Shelf (NSM) firmware is automatically updated (nondisruptively) on a new NSM module that has a non-
current firmware version.
NSM module firmware checks occur every 10 minutes. An NSM module firmware update can take up to 30
minutes.
• 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 NSM module, save all packing materials for use when you return the
failed NSM module.

• You can use the following video or the written steps to replace an NSM module.
Replacing an NSM module in an NS224 drive shelf
Steps
1. Properly ground yourself.
2. Physically identify the impaired NSM module.
The system logs a warning message to the system console indicating which module is impaired.
Additionally, the attention (amber) LED on the drive shelf operator display panel and the impaired module
illuminate.
