What you need to know about expansion shelves
You must understand the following information for a successful installation:

The system uses RAID6 controllers, twelve drives per RAID group, two RAID groups per shelf (AVA400/
AVA800).

You can hot-swap failed hard drives on an AltaVault expansion shelf, but you must run a CLI command to add it
to the RAID array. For more information see,
NetApp AltaVault Cloud Integrated Storage User’s Guide .

You must add a drive to the RAID controller using the Management Console or the command-line interface. New
expansion shelves cannot be added when system is running. Drives are not added to the RAID array
automatically. You must shut down the system, add the drives, and restart the system.

The two power supplies on an AltaVault expansion shelf are field replaceable units (FRUs).

The power supplies have fans:
– The PSU fans are for PSU cooling and maintaining chassis thermals.
– The fans continue to run, even if the power supply unit (PSU) itself fails.

If the PSU fails, do not remove it from the chassis until a replacement is immediately available.
It is recommended to replace the PSU as soon as possible to restore full redundancy.
Using LEDs to check the status of the system
You can check the front of the bezel to verify that the power is turned on, controller is active, system is halted, or
whether a fault has occurred in the chassis.
To check the status of the system
1. Locate the LEDs on the front of the bezel to verify the power is turned on, the controller is active, the system is
halted, or whether a fault has occurred in the chassis.
The image on the left displays a system bezel. The diagram on the right displays the system LEDs on the bezel.
