5-4 Installing Rack Components
Recommendations and Warnings
Please adhere to the following recommendations and warnings when installing
your rack system.
!
To improve rack stability when servicing system components, mount
heavier items such as a UPS or server in the bottom of the rack.
!
If your rack is a stand-alone unit and the rack is more than 75% filled
with components, consider installing the optional side stabilizer kit.
Refer to Table 6-2 for the part number of the side stabilization kit.
! WARNING
Two people are required when assembling the rack and
installing system components into the rack.
Installing the UPS
This section describes how to install an Uninterruptible Power Source (UPS)
into a system rack. See Figure 5-2.
The Uninterruptible Power Source (UPS) is a high-performance, line-interactive
supply that provides clean, reliable AC power to system rack components to
protect them from power blackouts, brownouts, swells, sags, surges, and
interference.
