Chapter 3 Troubleshooting 1250 Series Autonomous Access Points
Low Power Condition on Autonomous Access Points
When the access point determines that sufficient power is not available for full power operation, an error
message is logged and the Status LED turns amber to indicate low power mode (see the “Checking the
Autonomous Access Point LEDs” section on page 3-2 and the “Inline Power Status Messages” section
on page 3-8).
Tip If your switch is capable of supplying sufficient power for full operation (with a single radio module
installed) but the access point remains in low-power mode, your access point or your switch (or both)
might be misconfigured (see Table 3-3 and Table 3-5).
For full power operation with both radio modules installed, the access point can only be powered by
these options:
• Use the 1250 series power injector (AIR-PWRINJ4) on the switch port
• Use the 1250 series DC power module (AIR-PWR-SPLY1) to locally power the access point
For full power operation with only one radio module installed, the access point can be powered by these
options:
• Use the 1250 series power injector (AIR-PWRINJ4) on the switch port
• Use the 1250 series DC power module (AIR-PWR-SPLY1) to locally power the access point
• Use an 802.3af power source
Inline Power Status Messages
These messages are logged on the console port by the access point to report the power condition:
• %CDP_PD-4-POWER_OK: Full Power - AC_ADAPTOR inline power source—This message
indicates the access point is using the 1250 power module and can support full-power operation with
both radio modules.
• %CDP_PD-4-POWER_OK: Low Power - AC_ADAPTOR inline power source—This message
indicates the access point is using a non-1250 power module and cannot support full-power
operation.
• %CDP_PD-4-POWER_OK: Full Power - NEGOTIATED inline power source—This message
indicates the access point (with a single radio module installed) is operating at full power and has
successfully negotiated for 15.4 W of power from a Cisco switch supporting Cisco Intelligent Power
Management.
• %CDP_PD-4-POWER_OK: Full Power - HIGH_POWER_CLASSIC inline power source—This
message indicates the access point (with a single radio module installed) is operating at full power
because it has been configured for pre-standard compatibility mode and has detected a Cisco switch
that does not support Intelligent Power Management but is able to supply sufficient power to the
access point.
• %CDP_PD-4-POWER_OK: Full Power - INJECTOR_CONFIGURED_ON_SOURCE inline power
source—This message indicates the access point is operating at full power because it is connected
to a Cisco switch that supports Intelligent Power Management and the switch has been configured
with the power inline never command.
• %CDP_PD-4-POWER_OK: Full power - INJECTOR_CONFIGURED_ON_CURRENT_PORT
inline power source—This message indicates the access point is operating at full power because it
has been configured to expect a power injector on this port.
