Chapter 4. Installing optional devices

Using the rack cabinet mounting flanges
When you install optional devices in the rack cabinet, secure the device or the rails for
that device on rack mounting flanges. Some devices come with threaded rails or
threaded bars for the rails. Other devices require that you use cage nuts or clip nuts
to install them in the rack cabinet.
Note: NetBAY25 and NetBAY42 Rack cabinets require cage nuts, while NetBAY42
Enterprise Rack cabinets require clip nuts.
