Rack Mounting and Option Installation  

Chapter 2

2. Using the rack mount adapters as templates, position the adapters on 

the rack’s vertical rails where the mainframe is to be positioned. Be 
sure to align the adapter holes over center holes on the vertical rail 
(Figure 2-6).

Note

If you are using the Agilent E840xA VXIplug&play Compliant adapters 
(Option 925), position the adapters such that all three mounting holes are 
directly over holes on the rack’s vertical rails, and that the adapter flanges 
cover nine full EIA rack units with no overlap.

3. Slide channel nuts over the rack center holes to be used by the rack 

mount adapters.
