Low Power Condition on Autonomous Access Points Chapter 3 Troubleshooting 1250 Series 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.

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.
