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

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.
