Verifying Switch Operation
Step 1 Insert the power and relay connector into the power and relay connector
receptacle on the switch front panel (see Figure 4-11).
Step 2 Use a flathead screwdriver to tighten the captive screws on the sides of the power
and relay connector.
Caution Secure the wires coming from the power and relay connector so that they cannot
be disturbed by casual contact. For example, use tie wraps to secure the wires to
the rack.
