I have a strange problem with UPS on HP Servers, in that the server does not respond to the power input when connected to a UPS, just a small flicker from the power light when first plugged in, if I connect to the direct mains supply comes on OK
Other peripheral devices such as monitors are working OK, I have had this happen twice recently on two small sites, one was a new APC Ups on a new HP server, the other on a different site with a different brand of UPS but still on an HP Server.
If I take the UPS back to the workshop and load up with a PC etc all works OK, the batteries are fully charged and appear to be working normally.
Any one else had this and can point me in the right direction to resolve it.
