The 1550 series access point can be connected to more than one power source. The access point detects
available input sources and switches to the preferred power source using the following prioritization:
AC or POC power
External DC power
Power injector PoE power (same as 1520)
Internal battery power
Warning
This unit might have more than one power supply connection. All connections must be
removed to de-energize the unit.
Statement 1028
Warning
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
Statement 1023
Caution To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=).
Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate
power, which may cause the access point to malfunction and cause over-current
conditions at the power source. You must ensure that the switch port connected to the
access point has PoE turned off.
Caution Do not install the power injector and the power outdoors. They must be installed indoors.
Caution When the access point is installed outdoors or in a wet or damp location, the AC branch
circuit that is powering the access point should be provided with ground fault protection
(GFCI), as required by Article 210 of the National Electrical Code (NEC).
Three AC power cord options are available:
40-ft (12.2-m) power cord for installations in the US and Canada. One end of the power cord is
terminated with an access point AC power connector and the other end is terminated with an
AC plug (AIR-CORD-R3P-40NA=).
40-ft (12.2-m) power cord for use outside the US and Canada. One end of the power cord is
terminated with an access point AC power connector and the other end is unterminated.
(AIR-CORD-R3P-40UE=).
