# L2 POESTATUS

NOTES

- This maintenance command applies to the CXi II only.

- This maintenance command is not applicable to MiVoice Business for Industry Standard Servers (ISS).

## Qualifiers:

None

## Purpose:

Displays Power over Ethernet (PoE) status information for the CXi II controller.

## Details:

Current Total POE Power Consumption: The power currently being sourced by the 16 PoE ports.

Maximum POE Power Allowed: The total power available from the 16 PoE ports (120 Watts). When this limit is exceeded, power will be turned off to the ports, starting with port 16 to and ending with port 1, until less than 120 Watts is being consumed.

RX timeout errors: The total number of messages that were received and then rejected because of timeout conditions (for example, the messages were incomplete).

RX read errors: The total number of messages that were received and then rejected because of read error conditions.

RX other errors: The total number of messages that were received and then rejected because of other error conditions.

TX write errors: The total number of messages that were not transmitted because of write error conditions.

Checksum errors: The total number of messages that were received and then rejected because of checksum error conditions.

Protocol errors: The total number of messages that were received and then rejected because of protocol error conditions.

The following fields provide information about the 16 PoE ports:

pt | The port numbers from 1 to 16. Port 17 does not supply PoE.
cfg | The port PoE configuration, either enabled (yes) or disabled (no).
ena | The port enabled status. Displays ON if the port is configured for PoE and there is enough power available in the power budget (120 Watts, total). Otherwise, displays OFF. When a low-priority port loses power, this field displays OFF.
mode | The power source mode for the port. Can be used for debugging.
RESET | The port has been reset (usually because it has been disabled).
DISC_R | The PoE subsystem is discovering the port's resistative signature. The result is placed in the Oms field. If the resistative signature for a powered device is discovered, the port switches to CLASSI mode. Otherwise, it remains in DISC_R mode.
DISC_C | The PoE subsystem is discovering the port's capacitive signature.
CLASSI | If the resistative signature for a powered device is discovered, the PoE subsystem will then attempt to classify the power demands of the device. The result is placed in the CI field.
RAMP_U | After the port has been classified (CLASSI), the port PoE subsystem ramps up power to the device.
I-SAMP / V-SAMP | While the PoE subsystem is providing power to a device, it periodically samples the current (I) and voltage (V) consumption.
RAMP_D | A device has been unplugged and the port is powering down. After power down, the port switches DISC_R mode.
CI | The discovered Class type of the connected device. Each Class type has an allowable power consumption range (see below). The PoE module allocates the maximum amount for every range; for example, it allocates 6.49 Watts to all Class 2 devices. Note: Any device that does not support classification is assigned to Class 0 and allocated 7.5 Watts by the PoE subsystem.
Class | Power Consumption Range
0 | 0.44 to 12.95 Watts
1 | 0.44 to 3.84 Watts
2 | 3.84 to 6.49 Watts
3 | 6.49 to 12.95 Watts
Ohms | The discovered resistance of the connected device, in Ohms.
mA | The discovered current of the connected device, in milliamps.
Volts | The voltage on the port.
Watts | The power being consumed by the connected device, in Watts. If this field displays 0, then the device is not currently consuming power. A port may be enabled for PoE yet not provide power to the connected device.
Bdgt | The power budgeted for the port, in Watts.
ps | Port paused bit. Displays 1 if the port is paused; otherwise, displays 0. Used for debugging purposes only.
dny | Port power denied count.
OL | Port power overload fault count.
sht | Port short circuit fault count.
flt | Fault condition. Displays a message only if the port is out of service. Otherwise, displays NONE.
NONE | No fault, port in service
UV_OV | Under voltage / over voltage failure
UV_OV_SPIKE | UV / OV failure, plus a spike
PEAK_OC | Peak overcurrent
OVERLOAD | Overloaded port
DISCOVERY_R_FAIL | Classification failed
CLASS_VIOLATION | Power class type violation
DISCONNECT | Port has been disconnected
DISCO_R_A2D_FAIL | Analog to digital (A2D) failure
CLASSIFY_A2D_FAIL | Classify A2D failure
DEVICE_FAULT_A2D_FAIL | A2D failure
SAMPLE_DISC_A2D_FAIL | Current and voltage sample A2D failure
