The Cisco Aironet Power Injector products increase wireless LAN deployment flexibility of Cisco Aironet Access Points and Bridges by providing an alternative powering option to local power, inline power-capable multiport switches, and multiport power patch panels.
The single-port Cisco Aironet Power Injector combines 48-VDC power (supplied by the external power supply) with the data signal, sending both to the Cisco Aironet Access Point or Bridge.
The Cisco Aironet Power Injector Media Converter converts fiber media signals to Category 5 Ethernet media and combines the data signal with power for delivery to the access point or bridge. The power injector accepts 48-VDC power from either the barrel connector of the local power supply or an alternative 48-VDC power source.
The power injectors provide up to 15 W (depending on the Cisco power supply model) over the unused wire pairs of a Category 5 Ethernet cable, supplying enough power for a distance of 328 ft. (100 m) on the Cisco Aironet 350, 1100, 1200 Series Access Points and the Cisco Aironet 350 Series Bridges.
This guide covers the following Cisco Aironet Power Injectors:
Cisco Aironet Power Injector Media Converter
The Cisco Aironet Power Injector Media Converter provides both power and data to a connected Cisco Aironet Access Point. The device provides the following functions:
The power injector media converter is ideal for incorporating an access point into a fiber-optic network and can be used with 350, 1100, and 1200 series access points and 350 series bridges.
The power injector media converter receives data over the fiber-optic network through its MT-RJ fiber connector. The fiber-optic data signals are converted to Ethernet data signals and sent to the access point through the injector's Category 5 RJ-45 port. A Category 5 Ethernet cable connects the injector to the access point. The injector's power supply connects to a wall outlet or power strip to supply the power. An alternate 48-VDC power source can be used instead of the power supply. The power injector media converter can be mounted on most horizontal and vertical surfaces. To avoid overheating and possible failure, do not stack or tie together (bundle) the power injector and its AC power adapter.
TThe following illustration shows the key features of the Cisco Aironet Power Injector Media Converter.
The following illustration shows typical installation scenarios for the Cisco Aironet Power Injector Media Converter.
Cisco Aironet Power Injector
The Cisco Aironet Power Injector provides both power and data to a connected access point or bridge. The device serves the following functions:
The power injector provides an easy and economical way to provide data and power to an access point or bridge located in areas where power is not available. The power injector is used with the following Cisco Aironet wireless products:
A Category 5 Ethernet cable connects the power injector to a 10/100 Ethernet switch, hub, or network, and another cable carries power and data to the access point's or bridge's Ethernet port. The power injector's power supply connects to a wall outlet or power strip. The power injector can be mounted on most horizontal and vertical surfaces. To avoid overheating and possible failure, do not stack or tie together (bundle) the power injector and its AC power adapter.
The following illustration shows the key features of the power injector.
The following illustration shows a typical installation.
Unpacking the Power Injector
The following items are shipped with both models of the power injector:
If any item is missing or damaged, contact your Cisco representative or reseller.
Use the power supply that shipped with your access point to supply 48-VDC power for the injector. If you install the access point or bridge in an environmental air space such as above a suspended ceiling, check national and local safety codes to make sure that the Ethernet cable you connect to the unit meets applicable standards.
Release notes for these products are on Cisco.com. Browse to the following page:
Note The Cisco Aironet Power Injector Media Converter (AIR-PWRINJ-FIB) provides adequate fire resistance and low smoke-producing characteristics suitable for operation in a building's environmental air space in accordance with Section 300-22(C) of the National Electrical Code (NEC) and Sections 2-128, 12-010(3), and 12-100 of the Canadian Electrical Code, Part 1, C22.1.
Note The AC power adapter for either model power injector is not suitable for operation in a building's environmental airspace and should not be installed in these environments. When installing the power injector media converter into a building's environmental air space, the power supply pigtail option must be used.
Installing the Power Injector Media Converter
Follow these steps to install the power injector media converter:
Keyhole mounting holes
Tie wrap mounting slot
48-VDC barrel connector
Power cord retaining clips
7. Secure the media converter by mounting it to a vertical or horizontal surface using the supplied tie wrap mounting kit or using the keyhole mounting holes on the back of the unit.To avoid overheating and possible failure, do not stack or tie together (bundle) the power injector and its AC power adapter.
When power is applied to the power injector media converter, the Power LED glows green. When a device is discovered, the Status LED glows green continuously.
Installing the Power Injector
Follow these steps to install the power injector:
5. Connect a suitable 48-VDC power source to the power receptacle labeled DC48V.To avoid overheating and possible failure, do not stack or tie together (bundle) the power injector and its AC power adapter.
When power is applied, the Power LED glows green. The Device Status LED is dark until a device is discovered and then it glows green. If the power injector is not connected to a device capable of receiving inline power, or if it is connected incorrectly, the Power LED glows amber continuously.
You can mount both models to most vertical or horizontal surfaces using the supplied tie wrap mounting kit. If you need a more secure mounting method, you can also use the mounting keyholes on the bottom of the unit.
Using the Tie Wrap Mounting Kit
The supplied tie wrap mounting kit consists of the following parts:
Follow these steps to mount the power injector with the supplied tie wrap mounting kit. It may be helpful to refer to the illustration on page 11.
Using the Keyhole Mounting Holes
To mount the power injector to a vertical or horizontal surface using the keyhole mounting holes, you will need the following parts and tools:
Follow these steps to mount the power injector:
This table lists specifications for the power injectors:
The following information is for FCC compliance of Class B devices:
The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco's installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco's written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
•Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
Except where indicated, both models meet the following standards:
