c. Pull the logo on the front plastic bezel cover gently, rotate it 90 degrees clockwise and snap it
back into position. The rotated front plastic bezel cover is shown in Figure 11.
d. Replace the front plastic bezel cover on the Liebert GXT4. At this point, the UPS operation
and display panel and logo have been rotated 90 degrees clockwise, which provides upright
viewing for users.
5. Place the Liebert GXT4 and any battery cabinets on the support bases. Each Liebert GXT4 needs
two support assemblies, as shown in Figure 11.

2.4.2 Rack Installation
The Liebert GXT4 UPS and external battery cabinets (EBC), when installed in a rack enclosure, must
be supported by a shelf or rack-mount rails. The Liebert GXT4 UPS and EBC units ship with all
required hardware to allow rack-mount installation (not included with model numbers that end in
“E”). Because different rack-mount options install differently, refer to the installation instructions
provided with the rack mount kit being used.
