Cabinet Performance Grounding (High-Frequency Ground)

Signal interconnects between system cabinets require high-frequency ground return paths. Connect all

cabinets to site ground.

NOTE

In some cases, power distribution system green (green/yellow) wire ground conductors are too

long and inductive to provide adequate high frequency ground return paths. Therefore, a

ground strap (customer-supplied) should be used for connecting the system cabinet to the site

grounding grid (customer-supplied). When connecting this ground, ensure that the raised floor

is properly grounded for high frequency.

Power panels located in close proximity to the computer equipment should also be connected to the site

grounding grid. Methods of providing a sufficiently high-frequency ground grid are described in the next

sections.
