Metal Enclosure - Cisco Aironet 1520 Series Hardware Installation Manual

Hardware Features
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.
To provide inline PoE, you must use the 1520 power injector (AIR-PWRINJ1500-2=). Other power
Caution
injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which may cause
the access point to malfunction and cause possible over-current conditions at the power source.
Cable Modem
The access point cable configuration contains an internal cable modem for connection to the cable
network from the pole-mounted cable lines. The access point can be powered using the 40-to 90-VAC
(quasi-square wave AC) power provided by the cable network.
Note The access point uses a Scientific Atlanta DPC2100 cable modem board and 4015821 RF splitter.
The cable modem supports these main features:
•
•

Metal Enclosure

The access point uses a metal enclosure that can accommodate both indoor or outdoor operating
environments and an industrial temperature operating range of –40 to 131°F (–40 to 55°C). The access
point complies with NEMA 4 and IP67 requirements.
