restricted-access location. It has a separate protective earthing terminal
provided on the chassis in addition to the grounding pin of the power supply

Each AC power supply has an ejector lever that holds the power supply in place. The
ejector lever locks into the corresponding hole in the chassis on the left side of the AC
appliance inlet. For instructions for installing the power supply, see “Installing a Power
Supply in a J-EX4500 Switch” on page 88.
Each AC power supply comes with a power cord retainer (Figure 11 on page 23) that holds
in place the jumper cable shipped with the switch or the separately orderable power cord
with plug appropriate for your geographic location. The power cord retainer has a clip
and an adjustment nut. The L-shaped ends of the retainer clip hook into the bracket holes
on each side of the AC appliance inlet. The adjustment nut holds the jumper cable or
power cord in the correct position. For instructions for installing the power cord retainer,
see “Installing a Power Supply in a J-EX4500 Switch” on page 88.
