Power Considerations
Installation of your small cell module requires an additional
6 watts to power the Cisco Aironet 3600 access point. With a
USC 5310 module installed, the access point requires the full
Power over Ethernet Plus (PoE+) of 25.5 Watts at the egress
switch port and a cable run of less than 300 feet (100 meters).
Power options for the access point include:
• IEEE 802.3at POE+ 25.5 W delivered from the upstream
Ethernet switch
• Cisco 3600 Series Power Injector (AIR-PWRINJ4=)
• Cisco 3600 Series local power supply (AIR-PWR-B=)
The USC 5310 module has a power limit circuitry that shuts
down the module if it draws more power than allowed.
Installation Considerations
Install your small cell:
• in a central location, in an area where people are most likely
to make calls
• away from windows, to avoid the signal leaking outside or
external signals leaking in
• in an open area with airflow; not in a closed cabinet which
reduces the signal strength
If you have thick internal walls, or metal, fire or rotating doors,
plan to place units at either side of the obstruction at a distance
shorter than 49 feet (15 m). Install a unit across from a corner
to provide coverage on both sides of the corner.
