[computer-tech-support: 8328] Tripp Lite SMARTINT2200VS UPS fails to power Intel Xeon HP Proliant ML370 G6 server

Hi all,

I have recently obtained a Tripp Lite SMARTINT2200VS UPS in order
to provide electrical power for an Intel Xeon HP Proliant ML370 G6
Server in the case of power outage. When I simulate a power outage by
disconnecting the main power cable from an AC outlet, the server shuts
down immediately, although the UPS is fully charged. Further, I hear a
"cracking voice" near to the power supply fan of the server. The
strange thing is, that the UPS can provide electrical power up to 2000
Watt, whereas the server needs only 750 Watt to function. Where is
then the problem? In the UPS manual it is clearly stated that one does
not need to install the UPS on the operating system of the server in
order for it to work properly, i.e., it can work without a software.
It can sense a power failure immediately and it should be able to
provide enough power for the server. I was wondering if anyone out
there may have faced the same problem. Any hints or suggestions are
appreciated. For further information, I am running Linux Ubuntu
version 10 OS on the server for which there is no Tripp Lite software
to run a UPS power management software.

John
