PoE for Cisco 1242AG and 1310G Access Points

Dear All,

we purchased a Cisco 1242AG and a 1310G Access Point and in the DataSheet it was specified that these APs support Power-over-Ethernet. The problem is we don't see any RJ-45 port in either AP which could be used for connecting the AP to an PoE Switch. Can you please tell us how we can connect these APs to an 802.11af compatible PowerBridge (by Intermec) ? Thanks.

Hi Thorsten,

The 1242 should be good to go but the 1310 is powered quite differently. Have a look;

Connecting the Ethernet and Power Cables

1300 Series Power

Power

The access point/bridge receives inline power from the Cisco Aironet Power Injector (hereafter called the power injector). Dual-coax cables are used to provide Ethernet data and power from the power injector to the access point/bridge. The power injector is an external unit designed for operation in a sheltered environment, such as inside a building or vehicle. The power injector also functions as an Ethernet repeater by connecting to a Category 5 LAN backbone and using the dual-coax cable interface to the access point/bridge.

The power injector is available in two models:

Cisco Aironet Power Injector LR2 standard version (included with the access point/bridge)

48-VDC input power

Uses the 48-VDC power module (included with the access point/bridge)

Cisco Aironet Power Injector LR2T optional transportation version

12- to 40-VDC input power

--------------------------------------------------------------------------------

Note The power injector and the power module must not be placed in an outdoor unprotected environment. The power module must not be placed in a building's environmental air space, such as above a suspended ceiling.

Dual coaxial cable to run from the power injector to the 1300. See attached notes:

Cisco Aironet 1300 Series

Cisco Aironet 1300 Series Access Point/Bridge Power Injector

The Cisco Aironet 1300 Series Outdoor Access Point/Bridge Power Injector,converts the standard 10/100 BaseT Ethernet interface that is suitable for weather protected areas to a dual F-Type connector interface for coax cables that are more suitable for harsh outdoor environments. The Power Injector also provides power to the outdoor unit over the same cables with a power discover feature and surge protection. To support longer cable runs from your wireless network switch or router, the Power Injector LR is designed to accommodate up to a 100 meter coaxial cable run plus 100 meters of indoor cat5 cable?enabling total cable runs up to 200 meters. The Cisco Aironet 1300 Series Outdoor Access Point/Bridge ships with the Power Injector LR2 and an AC power supply.

Ethernet Ports

The access point/bridge dual-coax Ethernet ports consists of a pair of 75-ohm F-type connectors, linking the unit to your 100BASE-T Ethernet LAN through the power injector. The dual-coax cables are used to send and receive Ethernet data and to supply inline 48-VDC power from the power injector to the access point/bridge.
