Cisco Aironet 1250 Series Access Point Hardware Installation Guide

Chapter 2 Installing the Access Point

Connecting the Ethernet and Power Cables

Connecting the Ethernet and Power Cables

The access point receives power through the Ethernet cable or an external power module.

Figure 2-14

shows the power options for the access point.

Figure 2-14

Access Point Power Options

Power options for access points with dual radio modules:

•

Option 1—Switches without sufficient inline power can use the power injector:

–

1250 series power injector (AIR-PWRINJ4)

•

Option 2—Local power using the 1250 series DC power module (AIR-PWR-SPLY1)

Note

Current switches and patch panels do not provide enough power to operate the access point with dual
radio modules. At power-up, if the access point is unable to determine that the power source can supply
sufficient power, the access point automatically deactivates both radios to prevent an over-current
condition. The access point Status LED turns amber and an error log entry is created (refer to the

“Checking the Autonomous Access Point LEDs” section on page 3-2

and the

“Checking the

Autonomous Access Point LEDs” section on page 3-2

) or the

“Checking the Lightweight Access Point

LEDs” section on page 4-3

and the

“Low Power Condition for Lightweight Access Points” section on

page 4-7

).

Note

Access points with only a single radio module can be powered by IEEE 802.3af power sources, such as
switches and power panels.
