 Chapter 5. Rack planning 

127

The following features also are included: 

򐂰

A front stabilizer bracket, which can be used to secure the rack to the floor, as 
shown in Figure 5-6.

Figure 5-6   Rack with stabilizer bracket attached, being bolted to the floor

򐂰

As shown in Figure 5-7 on page 128, a recirculation plate is used to prevent 
warm air that is coming from the rear of the rack from passing under the rack 
and into the front of the servers. This is not required if the stabilizer bracket is 
installed.
