Figure2-12 Using a power adapter to connect the AP to a local power source
Connecting a local DC power source
No terminal block is provided with the AP. Purchase a terminal block from H3C as required.
As a best practice, use copper wires with 0.5 or 0.75 mm

(0.0008 or 0.0011 in
2
) cross sectional
area. The copper wires must comply with GBT3956-1997.
The input voltage range for the AP is 40 VDC to 55 VDC.
To connect a local DC power source:
1. Insert a flat-head screwdriver straight into a square-shaped hole in the terminal block.
This will open the round-shaped hole above the square-shaped hole.
2. Hold the screwdriver and insert one wire into the round-shaped hole in the terminal block.
Identify the positive and negative feed positions. The wiring sequence is positive to positive
and negative to negative.
3. Take out the flat-head screwdriver from the square-shaped hole.
The round-shaped hole will close, and the wire will be secured in place.
4. Repeat the procedure to attach the other wire into the terminal block.
