Chapter 3 Troubleshooting 1250 Series Autonomous Access Points
Low Power Condition on Autonomous Access Points
•
%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.
•
%CDP_PD-4-POWER_OK: Full power - INJECTOR_DETECTED inline power source—This
message indicates that the access point has detected the 1250 series power injector (AIR-PWINJ4)
and is operating at full power with both radios enabled. The power inline negotation injector
installed command does not have to be used to specify that the power injector is installed.
Note
To prevent possible over-current conditions, the power source must be an IEC60950
compliant limited power source.
•
%CDP_PD-4-POWER_OK: Full power - INJECTOR_CONFIGURED_OVERRIDE_SAFETY
inline power source —This message indicates the access point has been configured to override the
inline power checks and a power injector is installed.
Caution
When using the power inline negotiation injector override command, a power injector must always be
installed to prevent a possible overload condition with an underpowered power source.
•
%CDP_PD-2-POWER_LOW: All radios disabled - NEGOTIATED inline power source—This
message indicates the access point is in low power mode with all radios disabled because the Cisco
power source has indicated it is not capable of supplying sufficient power to the access point.
Note
A Cisco 1250 power injector might be required.
•
%CDP_PD-2-POWER_LOW: All radios disabled - LOW_POWER_CLASSIC_NO_INJECTOR
_CONFIGURED <platform name> (<MAC address>). —This message indicates the access point is
in low power mode with all radios disabled and has detected a CDP device that is unable to supply
sufficient power to the access point.
The< platform name> indicates the CDP device detected by the access point. The <MAC address>
indicates the MAC address of the CDP device, typically, the switch port.
Note
A Cisco power injector might be required.
Following the low power status message, two extra messages are displayed on the console port or
when using a Telnet session that identify the actions needed to resolve this low power problem:
–
Verify the required power injector is installed on this port: <platform name> (<Ethernet port>).
(where <platform name> indicates the CDP device detected by the access point and
<Ethernet port> indicates the Ethernet port of the CDP device.
–
If a power injector is installed, issue the command: power inline negotiation injector installed.
