submaster indicated he has no Support contract.  You can reach out to an EMC Service Partner in your area.  They can work through a Time&Materials quote to provide one or one SPS batteries.  While you can find these on Ebay, it can be difficult to ensure you get the right product - working with a Partner ensures you get the right parts.  Let us know if that helps!  Karl
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
