12. 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.
13. Verify that the attention (amber) LED on the shelf operator display panel is no longer illuminated.
The operator display panel attention LED turns off after the NSM module reboots. This can take three to
five minutes.
14. 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.

Hot-swap a power supply - NS224 shelves
You can replace a failed power supply nondisruptively in an NS224 drive shelf that is
powered on, and while I/O is in progress.
About this task
• If you are replacing more than one power supply, you must do so one at a time so that the shelf maintains
power.
•
Best practice:
The best practice is to replace the power supply within two minutes of removal from the
NSM module.
If you exceed the two minutes, the shelf continues to function, but ONTAP sends messages to the console
about the degraded power supply until the power supply is replaced.
•
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.
