Cisco Systems 1550 Manual Do Utilizador

When installing or replacing the unit, the ground connection must always be made first and 
disconnected last. Statement 1046

The access point can be installed on a streetlight pole and powered from a streetlight outdoor light 
control using the optional streetlight power tap adapter.

The access point can be powered by a light pole twist-lock outdoor light control that provides 
100-to 480-VAC 50/60 Hz power. Do not connect to an outdoor light control powered by higher voltages.

When powering the access point with AC power other than the streetlight power tap adapter, you must 
ensure that the following conditions are observed: 

AC power can be conveniently removed from the unit. The power should not be removed by 
disconnecting the AC power connector on the unit.

A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. 
Statement 1022

Before connecting or disconnecting a power cord, you must remove AC power from the power cord using 
a suitable service disconnect.

You must protect any AC power plugs and AC receptacles from water and other outdoor elements. 
You can use a UL-listed waterproofing enclosure suitable for covering the AC receptacle and AC 
power plug that supplies power to the unit as described in Article 406 of the NEC.

When you install the access point outdoors or in a wet or damp location, the AC branch circuit that 
powers the access point should have ground fault protection (GFCI), as required by Article 210 of 
the National Electrical Code (NEC).

Be very careful when connecting the streetlight adapter to Category 3 pole-top power. If you are not 
careful, you may electrocute yourself or fall. Statement 363

For additional important safety instructions for AC power cords, refer to the AC Power Cords for Cisco 
Aironet 1550 Series Outdoor Mesh Access Points document that shipped with your AC power cords.

To install an access point on a streetlight pole, follow these steps:

Before beginning the installation, ensure the AC power to the streetlight pole is turned off.

Turn off power to the AC power source at the designated circuits.

This unit might have more than one power supply connection. All connections must be removed to 
de-energize the unit. Statement 1028
