Cisco Aironet 1550 Series for Hazardous Locations Installation Guide
1
Overview
The Cisco Aironet 1550 Series Outdoor Mesh Access Point for Hazardous Locations (hereafter called
the access point or AP) is a modularized wireless outdoor access point designed for use in a mesh
network. The access point also supports wireless client access, point-to-point bridging,
point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity.
About the 1552 Access Point
The 1552 access point supports two radios (2.4-GHz and 5-GHz) and provides client access without the
need for a license. Depending on the radio, the access point can support 1 to 300 Mb/s data rates (for
specific data rates, refer to Appendix D, “Access Point Specifications”).
The 1552 access point supports the modularity of the 1520 series and allows flexibility in radio
configuration. In addition to full interoperability with 802.11n clients, the 1552 access point
interoperates with legacy clients and offers enhanced backhaul performance. The 1552 access point can
also be configured with an integrated ISA 100 or WirelessHART Gateway.
The access point is a standalone unit that can be pole mounted. The access point can also operate as a
relay node for other access points not directly connected to a wired network. Intelligent wireless routing
is provided by the patented Adaptive Wireless Path Protocol (AWPP). This enables each access point to
identify its neighbors and intelligently choose the optimal path to the wired network by calculating the
cost of each path in terms of signal strength and the number of hops required to get to a controller.
The access point is configured, monitored, and operated through a Cisco wireless LAN controller
(hereafter called a controller) as described in the Cisco Wireless LAN Controller Configuration Guide.
The Cisco Wireless Mesh Access Points, Design and Deployment Guide describes how to plan and
initially configure the Cisco mesh network, which supports wireless point-to-point, point-to-multipoint,
and mesh deployments. The controllers use a browser-based management system, a command-line
interface (CLI), or the Cisco Wireless Control System (WCS) network management system to manage
the controller and the associated access points. The access point supports hardware-based advanced
encryption standard (AES) encryption between wireless nodes to provide end-to-end security.

Chapter 1 Overview
Hardware Features
installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.:
NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54).
Statement 280
For your safety, read and follow these safety precautions.
1. Before you install an antenna, contact your Cisco account representative to explain which mounting
method to use for the size and type of antenna that you are about to install.
2. Select your installation site with safety, as well as performance, in mind. Remember that electric
power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
3. Contact your electric power company. Tell them your plans and ask them to come look at your
proposed installation.
4. Plan your installation carefully and completely before you begin. Each person involved in an
installation should be assigned to a specific task and should know what to do and when to do it. One
person should be in charge of the operation to issue instructions and watch for signs of trouble.
5. When installing your antenna, follow these guidelines:
– Do not use a metal ladder.
– Do not work on a wet or windy day.
– Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved
shirt or jacket.
6. If the assembly starts to drop, move away from it and let it fall. Because the antenna, mast, cable,
and metal guy wires are all excellent conductors of electrical current, even the slightest touch of any
of these parts to a power line completes an electrical path through the antenna and the installer.
7. If any part of the antenna system should come in contact with a power line, do not touch it or try to
remove it yourself. Call your local power company to have it removed safely.
8. If an accident should occur with the power lines, call for qualified emergency help immediately.
Multiple Power Sources
The 1550 series access point for hazardous locations supports these power sources:
•AC power—100 to 240 VAC (model 1552H and 1552SA access points)
•External 24 VDC (1552SD and 1552WU)
•Power-over-Ethernet (PoE)—56 VDC power injector (AIR-PWRINJ1500-2=), on model 1552H
only
Warning Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV)
requirements in IEC 60950 based safety standards. Statement 1033
The 1552 access point for hazardous locations can be connected to more than one power source. The
access point detects the available power sources and switches to the preferred power source using the
following default prioritization:
•AC power (1552H and 1552SA)
•External 24 VDC (1552SD and 1552WU)
•Power injector PoE power (1552SA/1552SD and 1552H)

Cisco Aironet 1550 Series for Hazardous Locations Installation Guide
Chapter 1 Overview
Hardware Features
Warning This unit might have more than one power supply connection. All connections must be removed
to de-energize the unit. Statement 1028
Caution To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=). Other power
injectors, PoE switches, and 802.3af/at power sources cannot provide adequate power, which can cause
the access point to malfunction and cause over-current conditions at the power source.
Caution The 1500 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only.
Note The Ethernet cable from the power injector to the access point (PoE-in port) must be not less than 10 ft
(3.1 m).
Caution When the access point is installed outdoors or in a wet or damp location, the AC branch circuit that is
powering the access point should be provided with ground fault protection (GFCI), as required by
Article 210 of the National Electrical Code (NEC). (1552H and 1552SA, not for 1552SD and 1552WU)
Ethernet (PoE) Ports
Note The 1552SA, 1552SD, and 1552WU access points do not support the PoE-In port.
The 1552 hazardous location access points support an Ethernet uplink port and a downlink port
(POE-Out). The 1552H access point also supports POE-In. The access point Ethernet ports use RJ-45
connectors (with a liquid tight adapter) to link the access point to the 10/100/1000BASE-T network. The
Ethernet cable is used to send and receive Ethernet data and to optionally supply inline 56-VDC power
from the power injector.
Note When a 1552H access point is powered by PoE, the PoE-Out port is not active.
The access point PoE-out (10/100/1000BASE-T) port uses an RJ-45 connector to provide LAN
connectivity and IEEE 802.3af power to a single peripheral customer device, such as a camera or sensor
gateway. The PoE-out port should not be connected to a switch or hub. The Ethernet MAC addresses are
printed on the bottom of the access point under the LEDs.
Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement
1023
The Ethernet cable must be a shielded outdoor rated Category 5e (CAT5e) or better cable. The access
point senses the Ethernet and power signals and automatically switches internal circuitry to match the
cable connections.

Network Deployment Examples
The access point is a wireless device designed for wireless client access and point-to-point bridging,
point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity. The access point
provides 5-GHz backhaul capability to link with another access point to reach a wired network
connection or to provide repeater operations for other access points.
The access point plays two primary radio roles: a root access point (RAP) or a mesh (non-root) access
point (MAP), which is the default role of all access points. When the access point has a fiber or wired
Ethernet or cable connector connection to the controller (through a switch), the radio role is called a
RAP. In order to be considered a RAP, the access point must be configured as a RAP. A RAP is a parent
node to any bridging or mesh network. A controller can support one or more RAPs, each one parenting
the same or different wireless networks. There can be more than one RAP for the same mesh network
for redundancy. RAPs and MAPs can support wireless clients on the 2.4-GHz and 5-GHz band. Client
access on 5-GHz is called universal client access.
When the access point does not have a wired Ethernet, fiber-optic, or cable connection to the controller,
the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface)
to other MAPs and finally to a RAP with an Ethernet or cable connection through a switch to the
controller. MAPs can also have a wired Ethernet connection to a local LAN and serve as a bridge
endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection).
Wireless Backhaul
The access point supports wireless backhaul capability using the 5 GHz radio to bridge to another access
point to reach a wired network connection to a controller (see Figure 1-11). The access point connected
to the wired network is considered a RAP in this configuration. The remote access point is considered a
MAP and transfers wireless client traffic to the RAP for transfer to the wired network. Control And
Provisioning of Wireless Access Points (CAPWAP) control traffic is also transferred over this bridged
link.

Hardware Features
Point-to-Point Bridging
The access points can be used to extend a remote network by using the 5 GHz backhaul radio to bridge
the two network segments as shown in Figure 1-12. To support Ethernet bridging, you must enable
bridging on the controller for each access point. By default this capability is turned-off for all access
points.
Wireless client access is supported; however, if bridging between tall buildings, the 2.4-GHz wireless
coverage area may be limited and possibly not suitable for direct wireless client access.
Figure 1-12 Access Point Point-to-Point Bridging Example
Point-to-Multipoint Bridging
The access points can be used as a RAP to connect multiple remote MAPs with their associated wired
networks. By default this capability is turned-off for all access points. To support Ethernet bridging, you
must enable bridging on the controller for each access point. Wireless client access can be provided over
the bridging link; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area may
be limited and possibly not suitable for direct wireless client access. Figure 1-13 illustrates an example
of access point-to-multipoint bridging.

Cisco Aironet 1550 Series for Hazardous Locations Installation Guide
Chapter 1 Overview
Hardware Features
Point-to-Multipoint Mesh Network
The access point is typically deployed in a mesh network configuration. In a typical mesh deployment,
one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs
without wired network connections use the backhaul feature to optimally link to a RAP that is connected
to the wired network. In the mesh network, the links between the access points are referred to as the
backhaul links.
Intelligent wireless routing is provided by the Adaptive Wireless Path protocol (AWPP). This enables
each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with the wired
network connection by calculating the cost of each path in terms of signal strength and the number of
hops required to get to a controller with signal strength given priority since signal strength determines
the data rate available for backhaul.
Figure 1-14 illustrates a typical mesh configuration using MAPs and RAPs.
