- Power Module Controller Batteries for Dell EqualLogic PS4100 PS4110

Arrived in two days and installed perfectly.

This worked perfectly with out Equallogic PS6100 storage array.

Anyone with an Equallogic controller knows that these "battery" (really a bunch of caps) devices fail, so having spares that aren't too old is important. This one was delivered fast and definitely is in good shape, no sign of issues with the caps leaking. It is also holding a charge after 3 days of use. However, it is throwing a warning during POST:<start post error>*****************************************************POST WARNING - 00/00/2000 00:00:48 Temp 020CC2F/PWRMOD/0d190002Part variable not found in C2F eeprom, Need to program*****************************************************<end post error>This does not seem to affect operation, but if you're one of those obsessive-compulsive types who really want everything to be perfect, this would bother you. IMPORTANT NOTE: I don't know if this is common to ALL of the devices sold here or if this is just the one that I received. Since it's working, I'm not going to try and replace it ("If it's not broke, don't fix it.") So, go ahead and get it, works fine (at least mine did), but just beware of this little error message.

Worked as expected and for considerably less than direct from Dell.

Received the power module very quickly and installed in SAN controller. Part was defective. It did not hold a charge.Exchanged for a replacement through Amazon, which was a very smooth and quick process.The replacement was also defective and would not hold a charge in the controller.Returned for a full refund.These parts did not appear to be new replacement parts.Ordered a module from another source which was packaged in such a way as to appear to be a new OEM replacement part and it worked perfectly.

Liked the fact thst the product is a perfect match with the defective component.Disliked the fact that it took a bit longer to receive the product.

First purchase: I was really scared to put this into my dell equallogic, but I had to do something or it was gonna die. I purchased and tried it out, the device recognized it and began reporting that all was well. Its been several weeks now with no issues.Second purchase: I received a battery that didn't work. The seller said they could not help me, that I needed to deal with Amazon directly. After reaching out to Amazon about this they allowed me to do a one to one swap. Once I received and swapped out the replacement, my server is reporting "good" on the battery. I sent the other one back and thus far we are good.

Worked correctly for PS4100.
