Chassis support mounting
To mount the chassis support:
1. Reinstall the chassis support assemblies in the rack and secure them to the captive nuts with
binder head screws. Also tighten the binder screws at the rear rack flange.
2. Tighten the screws attaching the two pieces of the chassis support assemblies.
Mainframe installation
To install the mainframe in the rack:
1. Lift the Model 707B or 708B mainframe onto the chassis supports and slide it into the rack.
2. The mainframe can be secured to the front rack flanges with user-supplied captive nuts and
binder head screws (four each).
The chassis supports hold the Model 707B or 708B in place while you are mounting the mainframe
to the front rack flanges. Once the instrument is secured, there may be a gap between the
mainframe and the chassis supports.
