AX4-5i SPS failed

Hi everyone

I have an old EMC AX4-5i system in my server room, and when I started to reallocate storage space I've found that it has some problem. Since I almost haven't used this system I don't know when it happened.

What I have right now is message in Navisphere Express "The storage system's Standby Power Supplies (SPSs) are not working properly. (0x7404)" and amber led with triangle and "!" sign. Both SPS's marked failed and both has same amber led.

I don't even know when and where this system was purchased, and surely there's no active service contract.

Is there something I could my myself with it ?

Thanks in advance
