Chassis To Chassis Grounding - Dell EMC VMAX3 Series Site Planning Manual

Grounding Racks

Chassis to chassis grounding

Rack to rack chassis ground connections are required to mitigate the risk of large AC power
transients in the data center affecting system performance. Large AC power transients can occur
from one or a combination of: electrical power grid problems feeding a facility; weak facility
grounding; powerful lightning storm strikes; or facility power equipment failure.
In multiple bay Dell EMC rack systems, use the rack to rack grounding kit, PN 106-562-209, to
provide chassis to chassis grounding. The kit provides straps for both the front and rear of the
cabinets. Both straps must be installed to provide chassis to chassis grounding.
In customer rack systems, mechanisms for tying racks together to provide the ground connection
can vary based on the rack provided by the customer and site facility preference. PN 106-562-209
is a rack to rack grounding kit for Dell EMC racks. The grounding kit may or may not work on racks
provided by the customer due to the variety of ground location positions on racks. If the grounding
kit does not work, a site electrician should add a ground cable tying the two racks common frame
ground points together with 6AWG wire.
