The single-port Cisco Aironet Power Injector provides The power injectors provide up to This guide covers the following Cisco Aironet Power Injector:. The device serves the following functions:.
The power injector connects to a wall outlet or power strip. Figure 1 shows the key features of the power injector. The Status LED indicates the following system status events:. Figure 2 shows a typical installation scenario. The typical power injector package contains the following items:. If any item is missing or damaged, contact your Cisco representative or reseller. Use the power cord that shipped with your power injector to supply power for the injector.
If you install the access point 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. Note The maximum distance that is supported for in-line power is ft.
Plug a Category-5 Ethernet cable into the port on the power injector labeled AP. Plug a Category-5 Ethernet cable into the port on the power injector labeled Switch. When power is applied, the Status LED blinks green at approximately 1.
If the power injector is connected incorrectly, the Status LED blinks green at 10 times per second. Secure the power injector by mounting it to a vertical or horizontal surface using the mounting keyholes on the bottom of the unit. You 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.
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. Plug a Category-5 Ethernet cable into the port on the power injector labeled AP. Plug a Category-5 Ethernet cable into the port on the power injector labeled Switch. When power is applied, the Status LED is amber.
Secure the power injector by mounting it to a vertical or horizontal surface using the mounting keyholes on the bottom of the unit. You 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. To mount the power injector to a vertical or horizontal surface using the mounting tabs, you will need the following parts and tools:. Using the holes in the power injector mounting tabs as a template, mark the locations on the surface where you will drill the holes for the wall anchors or screws.
If you are using 6 wall anchors, use a hammer to install them in the holes. Hold the power injector to the wall and align the mounting tabs on the power injector with the screw holes. Insert the 6 screws through the mounting tabs and into the holes in the wall or surface. 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.
This table lists specifications for the power injectors:. Model 1: 53 mm x Model 1: 0. IEEE Do not stack. Do not bundle the power injector and AC power cable.
If you are using the plastic mounting bracket, go to Step 3. Install the 10 wall anchor in the hole. Insert the 10 screw into the hole of the tie wrap and into the wall anchor. Tighten the screw just enough to keep it secure in the wall anchor. Slide the end of the tie wrap into the tie wrap mounting slot on the back of the power injector. Insert the end of the tie wrap into its locking slot and cinch it up.
Use a Phillips head screw driver to tighten the screw into the wall anchor. Follow these steps to mount the power injector using the plastic mounting plate:. The mounting plate has an adhesive back, so make sure the surface on which you intend to mount the plate is clean.
Remove the protective tape from the mounting plate to expose the adhesive backing. Press and hold the plate to make sure the plate adheres to the surface. Note You can also install the plate using two 10 screws, or you can use the screws to augment the adhesive backing.
Thread the plastic tie wrap through the slot in the mounting plate and then into the tie wrap mounting slot on the back of the power injector. Insert the tie wrap into its locking slot and cinch it up.
To mount the power injector to a vertical or horizontal surface using the keyhole mounting holes, you will need the following parts and tools:. Mark the locations on the surface where you will drill the holes for the wall anchors or screws. If you are using 6 wall anchors, use a hammer to install them in the holes. Start the 6 screws into the wall anchors or the surface.
Line up the large end of the keyholes on the power injector with the screws. Insert the power injector into the keyhole and slide it down into the small end of the keyhole. Note If the power injector is not securely fastened to the keyholes, remove it and slightly reduce the length the screws extend. Continue making small adjustments until you are satisfied. Injects power into two unused pairs in the Category 5 cable: 4 and 5 negative and 7 and 8 positive.
