No , i was referring to the battery backup unit within the server. Since
the server was installed by someone else across geographies i am not
aware of its details. I have found that the server does not have a
battery backup unit as seen from the output below:
**********************************
[root at node-103 ~]# ls /proc/acpi/battery/
[root at node-103 ~]#
**********************************
As of the UPS connectivity over LAN , I dont think this is done for the
server that i am using currently.
Thanks
