b. Gently push the PSU into the controller module until the locking tab clicks into place.
The power supplies will only properly engage with the internal connector and lock in place
one way.
To avoid damaging the internal connector, do not use excessive force when
sliding the PSU into the system.
6. Reconnect the PSU cabling:
a. Reconnect the power cable to the PSU.
b. Secure the power cable to the PSU using the power cable retainer.
Once power is restored to the PSU, the status LED should be green.
7. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See
the Part Return & Replacements
Option 2: Replace a DC PSU
To replace a DC PSU, complete the following steps.
1. If you are not already grounded, properly ground yourself.
2. Identify the PSU you want to replace, based on console error messages or through the red Fault
LED on the PSU.
3. Disconnect the PSU:
a. Unscrew the D-SUB DC power cable connector using the thumb screws on the plug.
b. Unplug the power cable from the PSU and set it aside.
4. Remove the PSU by rotating the handle up, press the locking tab, and then pull PSU out of the
controller module.
The PSU is short. Always use two hands to support it when removing it from the
controller module so that it does not suddenly swing free from the controller
module and injure you.
