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.
