Power On
Now you're ready to connect the EX4100 switch to a dedicated AC power source. The switch comes with the AC
power cord for your geographic location.
Here's how to connect the switch to AC power:
1. Attach an ESD grounding strap to your bare wrist, and connect the strap to the ESD grounding point on the switch.
2. Connect one end of the grounding cable to a proper earth ground, such as the rack .
3. Place the grounding lug (that's attached to the grounding cable) over the protective earthing terminal on the rear
panel as depicted in the following figures.
EX4100-24P, EX4100-24T, EX4100-48P, and EX4100-48T switch models
4. Secure the grounding lug to the protective earthing terminal using the two M5X10 mm screws with washer
5. Dress the grounding cable. Ensure that the cable doesn't block access to or touch other device components, and
that it doesn't drape where people could trip over it.
6. Ensure that the power supply is fully inserted in the rear panel of the switch.
7. On the rear panel, connect the power cord retainer clip to the AC power supply:
a. Push the end of the power cord retainer strip into the slot above the power cord socket until the strip snaps
into place. Ensure that the loop in the retainer strip faces the power cord. The power cord retainer clip extends
out of the chassis by 3 in. (7.62 cm).
b. Press the small tab on the retainer strip to loosen the loop. Slide the loop until there's enough space to insert
the power cord coupler into the power cord socket.
c. Plug in the power cord to the power cord socket.
d. Slide the loop toward the power supply until it's snug against the base of the coupler.
