Making Connections
Making Ground Connections
Use the procedure in this section for both the main shelf and the Expansion panel. 
After installing the TimeProvider shelf and/or the Expansion panel into the rack, 
make the grounding connections as follows. 
Front Access Shelf
To connect Chassis Ground on the front access chassis, connect a cable from the 
frame ground lug on the left side of the front panel to the proper grounding zone or 
master ground bar.
Rear Access Shelf 
To connect Chassis Ground on the rear access shelf, insert a grounding terminal 
block to one of the ground posts located on the lower left side at the rear of the shelf 
to the proper grounding zone or master ground bar. 
Recommendation: Although there are a number of methods for 
connecting the equipment to earth ground, Symmetricom 
recommends running a cable of the shortest possible length from 
the ground lug to earth ground.
