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).

• All other components in the system, including the other three DIMMs, must be functioning properly.
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 DIMM, save all packing materials for use when you return the failed
DIMM.
If you need the RMA number or additional help with the replacement procedure, contact technical support
