Hello,

For 2 days, we have a problem with SPS in our AX4-5F.

Please, see below error messages in Navisphere :

"The storage system's Standby Power Supplies (SPSs) are not working properly. (0x7404)"

"The storage system has disabled its write cache, most likely due to a hardware issue (shown as alerts on the Attention Required page). (0x720f)"

"Standby Power Supply A  = Faulted"

All cables are properly connected. The SPS active LED is solid orange.The SPS battery led is off.

We tried to reboot the SPS but same problem.

What we have to do? Is it a problem of battery, cable, ... ?

Thanks in advance for your help.
