Chapter 2. Installing a rack cabinet
The primary and expansion rack cabinets are 42U-high

racks. The primary rack cabinet comes with side
covers installed. The expansion rack cabinet does not come with side covers but includes the required
hardware for building a suite of racks. You need one standard rack cabinet per suite.
Notes:
1. Each stand-alone rack must be attached to the floor by a trained service technician according to your
local building codes.
2. The illustrations in this document might differ slightly from your hardware.
Statement 1
CAUTION:
To ensure safety, all configurations of the rack cabinet must be certified by a nationally recognized
testing laboratory in order to verify compliance with country-specific safety regulations. This process
ensures that the end product remains safe for the operator and service personnel under normal and
forseeable misuse conditions.
