Chapter 2 Installing the Access Point
Powering the Access Point
Step 3 Align the notch in the AC power cable connector with the key in the access point AC power connector,
and push the cable connector into the access point connector (see Figure 2-39 or Figure 2-40). When
fully seated, rotate the cable connector ring clockwise until hand-tight.
Step 4 Ensure that the antennas are connected to the access point before you apply power to the access point.
Step 5 Turn on the AC power at the designated circuits.
Connecting a DC Power Cable to the Access Point
When powering the access point with DC power, you must ensure that DC power can be conveniently
removed from the unit. The power should not be removed by disconnecting the DC power connector on
the unit.
Warning
A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.
Statement 1022
Warning
Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV)
requirements in IEC 60950 based safety standards.
Statement 1033
To connect a DC power cable, you need to supply these tools and material:
• Shielded outdoor-rated DC power cable (minimum 18 AWG) with outside cable diameter of 0.20 to
0.35 inch (0.51 to 0.89 cm).
• Adjustable or open-end wrench
• Small flat screw driver
• Two-pin DC power connector (Cisco supplied)
To connect the DC power cable to the access point, follow these steps:
Step 1 Before connecting DC power to the access point, ensure that the ground is connected to the access point
(see the “Grounding the Access Point” section on page 2-41.
Step 2 Turn off all power sources to the access point, including the DC power source.
Warning
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit.
Statement 1028
Caution When installing DC power to the access point, always connect the access point end of the cable FIRST.
When removing the DC power connector, always disconnect the access point end of the cable LAST.
If your access point contains a backup battery pack, you must press the reset button for 10 seconds or
more (see the “Disabling Backup Battery Power” section on page 3-10.)
Step 3 Use an adjustable wrench, a 22-mm socket, or a Sealcon S-2200 -WR wrench to remove the plug in the
DC power connector opening (see Figure 2-41 for the location of the DC power connector).
