Important!

The retaining clip is optional (if provided).

Step 2

Plug the power cables into the sockets.

Step 3

Adjust the retaining clips if needed for your power cords (if retaining clip was provided).

Step 4

Push the retaining clip back down over the cable (if retaining clip was provided).

Cabling the DC Power Supply

Figure 4-3

displays the location of the secondary grounding pads on front panel (left illustration) of the

switch chassis. After mounting the switch into the rack, connect the at least one of the secondary
grounds to the data center ground. After the switch is grounded, ESD wrist straps can be grounded by
connecting them to one of the attach points.

Important!

Grounding wires and grounding lugs (M4 x 0.7) are not supplied.
Wire size should meet local and national installation requirements.
Commercially available 4 AWG wire is recommended for installations in the U.S.
