Connecting To An Ethernet Network With Local Power; Powering Up The Access Point - Cisco AIR-AP1252AG-A-K9 Hardware Installation Manual

Powering Up the Access Point

Connecting to an Ethernet Network with Local Power

If your access point is connected to in-line power, do not connect the DC power module to the access
Note
point. Using two power sources on the access point might cause the access point to shut down to protect
internal components and might cause the switch to shut down the port to which the access point is
connected. If your access point shuts down, you must remove all power and reconnect only a single
power source.
Follow these steps to connect the access point to an Ethernet LAN when you are using a local power
source:
Connect a Category 5E (or higher) Ethernet cable to the RJ-45 Ethernet connector labeled Ethernet on
Step 1
the access point (see
Connect the 1250 series DC power module's output connector to the access point's DC-IN power
Step 2
connector (see
Plug the other end of the Ethernet cable into an unpowered Ethernet port on your LAN network.
Step 3
Plug the 1250 series DC power module's AC power cord into an approved 100- to 240-VAC outlet.
Step 4
For information on securing your access point, see the

Powering Up the Access Point

When power is applied to the access point, it begins a routine power-up sequence that you can monitor
by observing the three LEDs on the top of the access point. After you observe all three LEDs turning
green to indicate the starting of the IOS operating system, the Status LED blinks green signifying that
Cisco IOS is operational. When in an operational status, the Ethernet LED is steady green and blinking
green when passing Ethernet traffic. The sequence takes about 1 minute to complete. Refer to
"Checking the Autonomous Access Point LEDs,"
Lightweight Access Points"
When the sequence is complete, you are ready to obtain the access point's IP address and perform an
initial configuration. Refer to Cisco IOS Software Configuration Guide for Cisco Aironet Access Points
for instructions on assigning basic settings to the access point.
Be careful when handling the access point; the bottom plate might be hot.
Caution
If your access point is connected to in-line power, do not connect the DC power module to the access
Note
point. Using two power sources on the access point might cause the access point to shut down to protect
internal components and might cause the switch to shut down the port to which the access point is
connected. If your access point shuts down, you must remove all power and reconnect only a single
power source.
