This cable trough assembly may be used as the conduit for high frequency ground. In addition to possible
ground connections to Hewlett-Packard cabinets, the cable trough should be connected to the electrical
service ground at multiple connection points via a minimum #6 AWG (16mm2) wire ground conductor. See the
figure following for details.
Equipment grounding implementation details
If it has been determined to be necessary, connect all Hewlett-Packard equipment cabinets to the site ground
grid as follows:
Attach one end of each ground strap to the applicable cabinet ground lug.
Attach the other end to the nearest pedestal base (raised floor) or cable trough ground point (nonraised
floor).
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).
