Chapter3 Troubleshooting 1240AG Series Autonomous Access Points
Low Power Condition
If your inline power source is not able to supply sufficient power for full operation, you should consider
these options:
•Upgrade to a higher-powered switch
•Use a Cisco Aironet power injector on the switch port
•Use the 48-VDC power module to locally power the access point
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 power module and can support full-power operation.
•%CDP_PD-4-POWER_OK: Full Power - NEGOTIATED inline power source—This message
indicates the access point is operating at full power and has successfully negotiated for 12.95 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 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.
•%CDP_PD-4-POWER_OK: Full Power - INJECTOR_DETECTED_PD inline power source—This
message indicates the access point is operating at full power because it has detected a CDP packet
from another Cisco powerable device (PD). The access point power is being supplied from a power
injector or a non-Cisco power source because a Cisco power source does not transmit this type of
CDP packet.
•%CDP_PD-4-POWER_OK: Full Power - INJECTOR_DETECTED_MULTIPLE_MACS_ON_
HUB inline power source—This message indicates the access point is operating at full power
because it has detected multiple Cisco devices. The access point power is being supplied from a
power injector or a non-Cisco power source because a Cisco power source does not forward CDP
packets.
•%CDP_PD-4-POWER_OK: Full Power - NON_CISCO-NO_CDP_RECEIVED inline power
source—This message indicates the access point is operating at full power because it has not
received any CDP packets within the timeout period. This condition indicates your access point is
connected to a non-Cisco power source.
Note To prevent possible over-current conditions, the power source must be an
IEEE 802.3af
compliant power source or an IEC60950 compliant limited power source.
