Product Overview

Part Number

Description

AIR-PWRINJ-60RGD1=

60W outdoor rated power injector, with North America AC power plug.

AIR-PWRINJ-60RGD2=

60W outdoor rated power injector, International version with blunt-end cable.

AIR-PWRINJ-60-PMK=

Optional pole mount bracket for both the power injector models.

The power injector increases wireless LAN deployment flexibility of the access point by combining 55-VDC power with the data signal, and sending both to the connected access point.

The power injector combines 55-VDC power (supplied by internal power supply) with the data signal, sending both to the access point. The power injector provides up to 60 W over all four wire pairs of shielded, outdoor rated Ethernet cable.

The total length of the Ethernet cable from the AP to the switch must not exceed 320 ft (100 m). The wire gauge of the cable must be 26 AWG.

The Ethernet cable from the switch to the power injector must be a shielded CAT5e or higher Ethernet cable. The Ethernet cable from the power injector to the access point must be a shielded outdoor-rated CAT5e or higher Ethernet cable with a 0.20 to 0.35 inch diameter.

A shielded, outdoor Ethernet cable connects the power injector to a 10/100/1000 Ethernet switch, hub, or network, and another shielded, outdoor cable carries power and data to the access point’s Ethernet port. The power injector’s AC power receptacle connects an approved AC power cord to a wall outlet or power strip. The power injector can be mounted on most horizontal and vertical surfaces, but must be mounted in a vertical orientation to comply with safety requirements.

FCC Compliance of Class B Devices

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:

- Turn the television or radio antenna until the interference stops.

- Move the equipment to one side or the other of the television or radio.

- Move the equipment farther away from the television or radio.

- 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.

Important Safety Information

Mounting the Power Injector on a Wall

Caution All mounting methods on any wall surface is subject to the acceptance of local jurisdiction.

You can mount the power injector to most vertical or horizontal surfaces. The power injector does not ship with a mounting kit. You must provide the fasteners for the surface on which you intend to mount the access point. An optional pole mount kit, AIR-PWRINJ-60-PMK=, is also available.

The power injector has three mounting holes, one on the top end and two on the bottom end, that you can use to secure it to the surface. To mount the power injector using these screw holes, use three fasteners of at least 1-3/8 inches (35mm) in length, or of the appropriate type for the surface on which you are mounting the power injector on.

Note Though there are no ventilation openings on the power injector, you are recommended to keep some clearance around the front of the product.

To mount the power injector on a horizontal or vertical surface, follow these steps:

Step 1 Use the power injector to mark the positions of the mounting tab holes on the surface where you want to mount the power injector. See Figure 4.

Step 2 Drill holes at the locations you marked and insert the wall anchors. The holes need to be 9/32_inches (7mm) long. Use M5 or #10 wall anchors.

Step 3 Mount the power injector on the wall and align it with the screw holes. Use fasteners of at least 1-3/8 inches inches (35mm) in length. Insert the fasteners into the mounting tab holes and tighten.

Step 4 Ground the power injector, using the ground wire shipped with the power injector. Attach one end to the Earth Ground connector on the head of the power injector (see Figure 1), and attach then other end to a permanent ground connection. The ground lug used is an M6 stud.

Step 5 Proceed with the “Connecting Data and Power to the Injector” section.

Figure 4 Locations of Mounting Screw Holes – Marked 1, 2, 3

Pole Mounting the Power Injector Using AIR-PWRINJ-60-PMK=

You can mount the power injector on poles of up to 8 inches (25.4 mm to 203.2 mm) in diameter, using the optional pole mount kit, AIR-PWRINJ-60-PMK=.

The AIR-PWRINJ-60-PMK= pole mount kit consists of:

- Metal bracket

- 2 x Worm screw clamps

- 3 x M5X16 countersunk head Screw

- 4 x M6*110 hexagon head screw

- 8 x M6 flat washer

- 4 x M6 lock washer

- 4 x M6 hexagon nut

Note Though there are no ventilation openings on the power injector, you are recommended to keep some clearance around the front of the product.

To mount the power injector on a pole, use for guidance, and follow these steps:

Step 1 Mount the metal bracket of the AIR-PWRINJ-60-PMK= at the required position on the pole.

Step 2 Fasten the bracket to the pole using the worm screw clamps and the M6*110 hexagon head screw, flat washers, lock washers, and hexagon nuts. See Figure 5.

Step 3 Mount the power injector on pole bracket. The power injector has three mounting holes, one on the top end and two on the bottom end, that you can use to secure it to the pole bracket (see Figure 4). Mount the power injector using these screw holes and the three M5X16 countersunk head screws.

Step 4 Ground the power injector, using the ground wire shipped with the power injector. Attach one end to the Earth Ground connector on the head of the power injector (see Figure 1), and attach then other end to a permanent ground connection.

Step 5 Proceed with the “Connecting Data and Power to the Injector” section.

Figure 5 Pole-Mounting the Power Injector

Connecting Data and Power to the Injector

Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021

To connect the data cables and to power up the power injector, follow these steps:

Step 1 Plug a shielded outdoor rated Ethernet cable, using the factory-shipped waterproof RJ45 connector, into the DATA PWR OUT port on the power injector. Assembling of the waterproof RJ45 connector is shown in Figure 6.

Step 2 Plug the other end of the Ethernet cable into the Ethernet Port on the access point.

Note For detailed information about connecting the Ethernet cable to an access point, see the Hardware Installation Guide for that access point.

Step 3 Plug a shielded outdoor rated Ethernet cable, using the factory-shipped waterproof RJ45 connector, into the DATA IN port on the power injector. Assembling of the waterproof RJ45 connector is shown in Figure 6.

Step 4 Plug the other end of the Ethernet cable into your Ethernet switch, hub, or network.

Step 5 Plug in the AC power cord. For the RGD1=, plug the AC connector into suitable a AC receptacle. For the RGD2 = follow local codes to terminate the three wires of the AC cable. For AC power cord and wire sizes, see Table 1.

Step 6 Connect the other end of the power cord into a 100-VAC to 240-VAC power source
