3PAR 8400 controller node failure

[3PARUser1]

Hi im working with a HPE 3PAR StoreServ 8400 controller node system. One of the two controller nodes (Node 0) in Cage0 has failed (Node Offline due to failure 0xd).

On looking at the Cage details, the two Power Supplies of Cage0 are showing failed status. However the other controller node (Node1) using these two PSUs is working fine. The fan of both PSUs is operating on high speed however there is no environmental issue.

There are 3 expansion cages connected to this control cage. On checking their status, the "AC State" is showing failed status in all despite all of them functioning normally (operating via Node1 loop) and no PSU alarms can be seen on the back panel.

Can someone please guide me on this.

so replace failed node by new one and run node rescue
