PoE-Input

AC powered versions of AP1572EAC can be powered by UPOE compliant power sourcing equipment.
In addition to being powered by UPOE sources, the access point can also be powered by the
AIR-PWRINJ1500-2 power injector.
The access point also supports an Ethernet uplink port (PoE-In). The access point Ethernet uplink port
uses an RJ-45 connector (with weatherproofing) to link the access point to the 10BASE-T, 100BASE-T
or 1000BASE-T network. The Ethernet cable is used to send and receive Ethernet data and to
optionally supply inline power from the power injector or a suitably powered switch port.
The access point senses the Ethernet and power signals and automatically switches internal circuitry to

match the cable connections.
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.
Depending on the version of the AP, a 1572 series access point supports these power sources:
•
•
The 1572EAC access point can be powered via the PoE input from an in-line power injector or a suitably
powered switch port. The AIR-PWRINJ1500-2= power injector can be used.
Do not place the power injector in an unprotected outdoor environment because water could get into the

power injector and cause a short circuit and possible fire.
Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV)

Restrictions on Features under Different Operating Conditions

To limit the maximum power consumption and ensure thermal integrity of the access point, there are
factory-defined restrictions on the features that are active under a given operating condition. This is
different for different versions of the AP.
The following restrictions are applicable to all versions under all operating conditions:
•
OL-32138-01
Power-over-Cable on AP1572IC and AP1572EC versions
AC power on AP1572EAC version
The cable modem will be disabled when the small form-factor pluggable (SFP) port is enabled:
If an SFP device is detected on startup, the cable modem will be disabled and remain disabled
–
until the AP is rebooted.
If no SFP device is detected on startup, the SFP port will be disabled and remain disabled until
–
the AP is rebooted.
