Supported Power Sources
Supported Power Sources
The CMAP supports the following power sources:
■
Power over Cable (POC): 40 to 90V AC supplied through the RF coaxial cable (attached
to Connector B) that is connected to the cable modem termination system (CMTS)
backbone. POC is the primary and conventional source of power for the CMAP.
■
DC power (via DC connector): External 12 VDC. Use this only when staging or
debugging the CMAP.
NOTE:
PoE output is disabled when the CMAP is powered via the 12 VDC connector.
Heaters
The CMAP includes two built-in heaters that permit operation at extremely low
temperatures. They are typically on below 0 degrees C.
The heaters are enabled by default. If preferred, the access point heater can be disabled
from the Web interface. The cable modem heater cannot be disabled.
