Chapter 3 Troubleshooting 1240AG Series Autonomous Access Points
Low Power Condition
• %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.
• %CDP_PD-2-POWER_LOW: All radios disabled- LOW_POWER_CLASSIC_INJECTOR_
CONFIGURED_ON_ANOTHER_PORT <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. A power injector has been
configured, but it is for another port. It is likely that the access point has been relocated and has not
been reconfigured for a new power injector.
The <platorm 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 when using the console
port or a Telnet session that identify the actions needed to resolve this low power problem:
1. Verify the required power injector is installed on the new 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.
2. If a power injector is installed, issue the command: power inline negotiation injector installed.
• %CDP_PD-2-POWER_LOW: All radios disabled- HIGH_POWER_CLASSIC_NOT_
CONFIGURED inline power source <platform name> (<MAC address>)—This message indicates
the access point is in low power mode with all radios disabled and has detected a Cisco switch that
does not support Intelligent Power Management, but should be able to supply sufficient power. The
access point must be configured for pre-standard compatibility.
The< platform name> indicates the Cisco platform detected by the access point. The <MAC
address> indicates the MAC address of the switch port.
Note You need to upgrade the software on the Cisco switch to support Intelligent Power
Management or configure the access point for pre-standard compatibility.
