General System and Facility Guidelines
Grounding Systems
Good—Use the raised floor structure as a ground grid. In this case, the floor must be designed as a ground
grid with bolted down stringers and corrosion resistive plating (to provide low resistance and attachment
points for connection to service entrance ground and HP server equipment). The use of conductive floor
tiles with this style of grid further enhances ground performance. The structure needs to be mechanically
bonded to a known good ground point.

Equipment Grounding Implementation Details

Connect all Hewlett-Packard equipment cabinets to the site ground grid as follows:
1. Attach one end of each ground strap to the applicable cabinet ground lug.
2. Attach the other end to the nearest pedestal base (raised floor) or cable trough ground point (nonraised
floor).
3. Check that the braid contact on each end of the ground strap consists of a terminal, and connection
hardware (a 1/4-in. (6.0-mm) bolt, nuts, and washers).
4. Check that the braid contact connection points are free of paint or other insulating material and treated
with a contact enhancement compound (similar to Burndy Penetrox).
