The 1552E, 1552EU, and 1552I access points have a 3-pin, threaded AC power connector. Table 3 lists the power cord options available when you use AC power.
Table 3. AC Power Cord Options
Power cord, 40 ft, North American Plug
Power cord, 40 ft, European Harmonized, Unterminated
Power cord, 4 ft, Street Light Tap
The 1552H model requires a discrete wired connection to internal terminal block.
The AIR-CORD-R3P-40UE= connects to the access point on one end, and is not terminated on the other end. You will need to source a plug appropriate for your installation.
When AC power is not used (for example, when you use PoE or 12 VDC to power the access point), you should cover the unused connector. A cover is included with the power injector and is also available from Remke (visit http://www.remke.com and search for part number 75-0086).
Power over Ethernet
When you power the access point over Ethernet, the access point does not supply 802.3af PoE to an Ethernet-attached device. When you use Power over Ethernet, use the power injector listed in Table 4.
Table 4. Power Injector for Use with Power over Ethernet
1520/1550 Series Power Injector
Do not use any other power injector or switch for Power over Ethernet with the 1550 Series access points. The 1550 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 your local electrical regulations.
The 1550 Series access points use a standard RJ-45 Ethernet connector. Cisco does not provide an Ethernet cable for the 1550 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 1522C and 1552CU are 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 1552C and CU; it does not need to be separately ordered.
All Cisco Aironet 1550 Series Access Points support power from an external 12 VDC power supply, minimum 50 watts. A terminal block is included with your access point for this purpose, with liquid-tight adapters to weather-proof the connection. When using DC power, please consult the Hardware Installation Guide for instructions on how to correctly assemble the connector.
The 1550 Series can be installed with redundant power sources. When multiple power sources are available, the access point will use power in the following priority:
1. AC power or Power over Cable
2. DC power
3. Power over Ethernet
The Cisco Aironet 1550 Series Access Points can be deployed with a rechargeable lithium-Ion battery for backup power during power outages (Table 5).The battery provides approximately one to two hours of power with typical traffic volume (50 percent duty cycle). Actual battery time will vary depending on several factors, including traffic volume, temperature, and whether an auxiliary device draws Power over Ethernet. Note that the battery can be used only with the 1552E and 1552EU models. The battery can be configured to the access point when ordering, customer installed, or replaced in the field.

1520/1550 Series Battery Backup Unit
Cisco Aironet 1550 Series Access Points are equipped with a combination of radios operating in the 2.4- and 5-GHz bands. Both radios are capable of two transmit and three receive streams using Maximal Ratio Combining (MRC), which takes advantage of multipath signals received across up to three antennas to improve signal quality.
The 1552C and 1552I have internal omni antennas (2 and 4 dBi gain for 2.4 and 5 GHz respectively). No antennas are required to be ordered with these models. For the other 1550 models, table 6 describes the antennas available for the 1550 Series, listing part numbers for the antennas, as well as gain and other details.

As in Table 1, the "x" is a placeholder for the regulatory domain designator. Please see the note following Table 1 for more information.
Cisco Aironet 1550 Series outdoor access points can be ordered with unified (controller-based) software or with autonomous software. To operate as part of a mesh network (either as a root access point or mesh access point), the unified software is required. The autonomous, or standalone, software allows the access point to operate independently to serve clients and allows the access point to function as a work group bridge (WGB). The two software option part numbers are listed in Table 8. If no software is selected, the default selection is SWAP1500-BTIMGE-K9.

1550 Strand Mount Bracket Kit
The pole-mount kit is adjustable for any pole angle: horizontal, vertical, and any angle in between. It can also be used to mount the access point to a flat surface, such as a wall. To prevent the mounting bracket and access point from fusing together, anti-seizing compound is included with the access point. The pole- mount kit includes two stainless-steel-band straps and buckles to fit poles up to 16 inches in diameter. For larger poles, consult a local provider. The banding can be secured using the tool listed in Table 10.

The Cisco Aironet 1550 Series Access Points can be connected to the network wirelessly or through a wired Ethernet, fiber, or cable modem connection.
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). RAPs connect to the network through a wired connection, either Ethernet, fiber, or cable modem. Liquid-tight adapters are provided with your access point to prevent water ingress.
The 1550 Series supports 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.
Alternatively, the 1550 Series can use one of the temperature-rated Small Form-Factor Pluggable (SFP) modules. There is also an optional kit with fiber reels to store excess fiber inside the access point (Table 12).
