Aironet 1310, power injector and poe cable

Unanswered Question
Jan 11th, 2008

Hello,

Can the power injector delivered with aironet 1310 be supplied by a PoE RJ45 cable rather than the traditionnel DC adapter?

The problem is, i thought Aironet 1310 was PoE. Which means it can be power supplied by a rj45 cable.

But, when i openned my brand new 1310 box, i realized that 1st, it needs that Power Injector to work and that 2nd, Power injector needs a power supply...

Usually when i buy a PoE access point, I just plug in my PoE rj45 cable and its power supplied :)

Anyway, i hope there's an issue for this because where the 1310 should be placed, there's only a PoE rj45 cable arriving.

Thanks in advance,

lachapelle

I have this problem too.

Hi lachapelle,

Sadly the 1310 cannot be powered by PoE ,but, the Power Injector can be up to 100 meters away from the unit.

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.

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.

Thanks for the reply.

I'll have to put coax cable for about 30 meters. I suppose i can buy 75ohm coaxial cable anywhere.

But what about for the connectors? Are they easily available? Do I just ask for F-type connectors? Or is there any extra detail i need to specify?

Anyway, thanks for all those clarifications,

cheers,

Hi lachapelle,

First off, you are most welcome!

Cisco Part# AIR-CAB100DRG6-F will work (100 feet)

Or,

You can order up a custom length cable (RG6 Coax with F-Type connectors). Here is an example of someone who makes up custom cables (probably good to get them made up by the experts :);

Hope this helps!
