Fixed rack installation
System 40 systems are either shelf mounted or mounted directly in a rack.
Rack mount
Parts list
Table 1-1 lists the supplied parts required to rack mount a typical System 40 chassis.
Rack preparation
1. Select a location in the rack.
2. Hold up the system at the selected location in the rack. The four slotted mounting holes in the front panel dictate the location
of the captive nut fasteners on the front rack rails. Mark where the fasteners are to be installed.
3. Referring to Figure 1-1, install four fasteners so the captive nuts are located behind the appropriate holes on the front rack rails.
