■ Power cords appropriate for your geographical location. See “AC Power Cord
Specifications for an EX4500 Switch” on page 57.
WARNING: Ensure that the power cords do not block access to switch components
or drape where people can trip on them.
To connect AC power to the switch:
1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to the ESD point on the chassis.
2. Ensure that the power supply is fully inserted in the chassis. See “Installing a
Power Supply in an EX4500 Switch” on page 74.
3. Squeeze the two sides of the power cord retainer clip, and insert the L-shaped
ends of the clip into the holes in the bracket on each side of the AC appliance
inlet. See Figure 36 on page 90.
