SKU

Description

AIR-PWRINJ1500-2

1520 Series Power Injector

Do not use any other power injector or switch provided for Power over Ethernet with the 1520 Series access points. The 1520 Series is approved for use only with the AIR-PWRINJ1500-2. You must also specify the country type power cord for the power injector.
The AIR-PWRINJ1500-2 is for indoor use only. It has built-in surge protection, but you may also need to install a surge protector at the building entry point. Please check with your local electrical regulations.
The 1520 Series access points use a standard RJ-45 Ethernet connector, unlike the military connector used on the 1500 Series. Cisco does not provide an Ethernet cable for the 1520 Series. You will need to source an outdoor-rated, Category 5 or better Ethernet cable and shielded RJ-45 connectors from a local supplier. Liquid tight adapters are provided with the access point to seal this cable entry point from weather.

Power over Cable

The 1522PC is powered by the CATV plant power supply system over coaxial cable through its F-connector. A cable plant power supply system is built into the 1522PC; it does not need to be separately ordered.
The spare power supply listed in Table 5 is also available as a replacement part.

1. AC Power or Power over Cable

2. DC Power

3. Power over Ethernet

4. Battery (see the "Battery" section later in this ordering guide)

Antennas

The 1520 Series access points are equipped with a combination of radios operating in the 2.4- and 5-GHz bands. Some models can also operate in the 4.9-GHz band. The 5-GHz and 4.9-GHz radios use a single transmit and receive stream, while the 2.4-GHz radio performs Maximal Ratio Combining (MRC), which takes advantage of multipath signals received across up to three antennas to improve signal quality.
Table 7 identifies the type (2.4 or 5 GHZ) of antennas and the number of each type used by the 1520 Series.

1The 2.4-GHz radio can operate with fewer than the listed number of antennas. However, optimal performance is achieved when using the maximum number possible. Moreover, using less than the total number of antennas supported leaves the unused antenna connectors exposed to the weather; they will need to be covered.

Antennas must support your desired radio operating range, which varies by regulatory domain and model. Please see the appendix for the frequency range your access point operates.
Table 8 describes the antennas available for the 1520 Series, listing part numbers for both 2.4-GHz and 5-GHz antennas, as well as gain and other details. All antennas are white or off-white except where noted.

Network Connection

The 1520 Series access points can connect to the network wirelessly or through a wired Ethernet, fiber, or cable model connection.

Wireless

An access point that connects to the network through another access point over a wireless backhaul is known as a mesh access point (MAP). The backhaul radio is built in, and no wired connection is needed for MAPs.
An access point that also acts as the gateway for mesh nodes is known as a root access point (RAP), and connects to the network through a wired connection, either Ethernet, fiber or cable modem. (Note that a remotely located RAP may also connect to the network by connecting a separate wireless bridge to its Ethernet port, labeled "POE-In.") Liquid-tight adapters are provided with your access point to prevent water ingress.

Ethernet

The 1520 Series access points support 10/100/1000 Gigabit Ethernet using a shielded RJ-45 connector with minimum Category 5 cable. Please see your local supplier for an outdoor-rated cable and shielded connectors.

Fiber

Alternatively, the 1520 Series access point can use one of the temperature-rated fiber Small Form-Factor Pluggable (SFP) modules listed in Table 11.
