Getting to Know the Access Point Features
ZoneFlex 7761-CM Cable Modem Access Point

NOTE The LEDs also do not indicate whether the AP is in standalone mode or if
ZoneDirector is managing the AP. To check if ZoneDirector is managing the access
point, log into the ZoneDirector Web interface, go to the Access Points page, and
then search for the access point’s MAC address. If you are unable to find the access
point, then it is very likely in standalone mode. If you have multiple ZoneDirector
devices on the network, make sure you check each one of them.
CMAP Supported Power Sources
The CMAP supports the following power sources:
• Power over Cable (POC): 40 to 90 VAC 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.
CMAP Heaters
The CMAP includes two built-in heaters (one for the access point and one for the
cable modem) that permit operation at extremely low temperatures. They are
typically on below 0º C (32º F).
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.
CMAP Operation
Refer to the 7761CM Dual Band 802.11n Outdoor Access Point with Integrated
Cable Modem Installation Guide for information on the Cable Modem configuration
and operation procedures.
