What should the technician do?

One of the servers in a datacenter is set to use the 1+1 power redundancy option with a hot spare. The server uses 1100W PSUs. An SNMP trap has been sent alerting the technician to a PSU failure.

Since this is the "hot spare" PSU, the technician chooses an available, higher capacity Titanium PSU. After replacing the PSU and connecting the power cable, the PSU indicator/handle flashes green, then turns off.

The technician has taken the following actions:

– Reseated the PSU

– Checked the firmware version

– Checked the cable connections

The PSU continues to flash green then turn off.

What should the technician do?
A . Check the Titanium PSU in another server to ensure it is not defective
B . Wait for the PSU firmware to update
C . Replace the 1100W PSU with a matching unit
D . Change the redundancy from 1+1 to 2+0 and then enable the hot spare
