you might need a pointed device, such as a screwdriver, to press the on/off

time the indicators are turned on and off several times. The 2145 UPS-1U then
enters
normal

places the 2145 UPS-1U in
standby
mode. You must then unplug the 2145 UPS-1U
to turn off the unit.

down the SAN Volume Controller node that it is connected to. Always follow the
