Cisco Systems, Inc. www.cisco.com Cisco Aironet Power Injector AIR-PWRINJ6= GuideThis document describes the Cisco Aironet series acc ess point power injector AIR-PWRINJ6= (referred to as the power injector in this document) and provides instructions for mounting them. Product OverviewThe Cisco Aironet Power Injector AIR-PWRINJ6= in creases wireless LAN deployment flexibility of supported Cisco Aironet Access Points by providing an alternative powering option to local power, inline power-capable multiport switch es, and multiport power patch panels. The single-port PoE injector provides up to 30 Watts and is compliant with IEEE 802.3af (15.4 W) and IEEE 802.3at (30 W) systems. This power injector is for use with the Cisco Aironet 2800 series and 3800 series access points. Note The Cisco Aironet Power Injector AIR-PWRINJ6= is not weatherproof and hence is not meant to be used outdoors. A Category 5 or better Ethernet cable connects the injector to a 10/100/1000 Ethernet switch, hub, or network, and another cable carries power and data to the access point’s WAN Ethernet port. The power injector™s built-in power supply has a C13 connector th at connects to a wall outl et or power strip. The power injector connects to a wall outlet or power strip. CautionTo avoid overheating and possible failure, do not stack or tie together (bundle) the power injector and its AC power cable.

The LED remains green when powering the Ac cess Point even if the uplink is not connected. The LED is green for showing that the power injector is providing power to the Access Point.

3Cisco Aironet Power Injector AIR-PWRINJ6= Guide Product Overview Unpacking the Power InjectorThe typical power injector packag e contains the following items: †Power injector †Power cord †URL Pointer Card and China RoHS Statement If any item is missing or damaged, cont act your Cisco representative or reseller. Additional RequirementsUse the power cord that shipped with your power injector to supply power for the injector. If you install the access point in an environmen tal air space such as above a su spended ceiling, check national and local safety codes to make sure that the Ethern et cable you connect to the unit meets applicable standards.Note† The AIR-PWRINJ6= should not be installed in the plenum airspace. †The maximum distance that is supported for in-line power is 328 ft. (100 m), including the length of the 6.5-ft. (2-m) Ethernet cable provided with the power injector. Disable PoE on the Connected SwitchportSometimes, when the AP is connected to the AIR- PWRINJ6 that is cabled to a 802.3af PoE-enabled switchport, it might not function properly. To resolv e this, disable PoE on the switchport connected to the AIR-PWRINJ6= injector. Failure to do so will result in the injector not supplying full power to the AP and might cause issues such as disabled radios since the AP will inte rmittently receive only 15.4W of power. To disable PoE on the connected switchport, execute the power inline never command at the CLI prompt of the Cisco switch when it is in the interface config mode.

4Cisco Aironet Power Injector AIR-PWRINJ6= Guide Installing the Power InjectorInstalling the Power InjectorFollow these steps to install the power injector: 1.Plug a Category-5 Ethernet cable into th e port on the power injector labeled AP.2.Plug the other end of the Ethernet cable into the WAN uplink Ethernet port of the access point. 3.Plug a Category-5 Ethernet cable into th e port on the power injector labeled Switch .Note Ensure that PoE is disabled on this switchport before it is connected to the AIR-PWRINJ6= injector. For more information, go to Disable PoE on the Connected Switchport, page 34.Plug the other end of the Ethernet cable into your 10/100/1000 Ethernet switch, hub, or network. 5.When power is applied, the Status LED is amber. When the AP is detected, the Status LED glows solid green. 6.Secure the power injector by mounting it to a ve rtical or horizontal su rface using the mounting keyholes on the bottom of the unit.

5Cisco Aironet Power Injector AIR-PWRINJ6= Guide Installing the Power Injector Mounting InstructionsYou can mount the power injector to most vertical or horizontal surfaces using the mounting tabs on the top right and bottom left of the unit. Using the Mounting TabsTo mount the power injector to a vertical or horizontal surface using the mounting tabs, you will need the following parts and tools: †Two #6 plastic wall anchors if mounting to a drywall surface †Two #6 x 1-in. (2.5 cm) sheet-metal screws †A drill and a 3/16-in (0.48-cm) drill bit †A Phillips head screw driver †A small hammer Follow these steps to mo unt the power injector: 1.Using the holes in the power injector mounting tabs as a template, mark th e locations on the surface where you will drill the holes for the wall anchors or screws. 2.Drill a 3/16-in. (4.7-mm) hole at each marked location. 3.If you are using #6 wall anchors, use a hammer to install them in the holes. 4.Hold the power injector to the wall and align the mounting tabs on the power injector with the screw holes. 5.Insert the #6 screws through the mounting tabs and into the holes in the wall or surface. 6.Use a Phillips head screwdriver to drive the screws into the surface. Note If the power injector is not securely fastened, continue making small adjustments until you are satisfied.
