4.1 Cabling the AC Power Supply
4.1.1 Grounding the Switch
After mounting the switch into the rack, connect the switch to the data center ground. Figure 4-1
displays the location of the grounding pads located on the front panel (left illustration) and rear panel
(right illustration). After the switch is grounded, ESD wrist straps can be grounded by connecting them
to one of the grounding pads.
Important! Grounding wires and grounding lugs (M4 x 0.7) are not supplied. Wire size should meet local and
national installation requirements. Commercially available 6 AWG wire is recommended for
installations in the U.S.
