is flashing red and the alarm is sounding, the voltage
range setting might not be correct. When a SAN Volume Controller is
connected to the UPS 5125, the SAN Volume Controller automatically adjusts
the voltage range setting. Take no action for this alarm condition unless it
persists for more than five minutes after a SAN Volume Controller has been
connected to this UPS 5125 and powered on.

Installing the support rails for the SAN Volume Controller
The support rails should be installed to hold the SAN Volume Controller.
Before you install the support rails, perform the following tasks:
v Determine where the SAN Volume Controller is to be installed in the rack.
v Refer to the EIA markings on the rack and decide where you are going to install
the support rails.
Perform the following steps to install the support rails:
1. Check the labels on the support rails; each rail has a label that indicates which
is the front end of the rail and whether the rail is for the left or right side of the
rack. Perform this procedure for both rails.
2. Put your finger against the side of the latch-lever

and put your thumb
against the front of the latch-lock
