27“.

Slot <slot-id> POE usage has exceeded threshold of < 1 - 99 >%

Indicates that POE usage in the indicated slot has exceeded the configured threshold for the module, as specified by the last execution of the power threshold or power slot < slot- id > threshold command. (Note that the switch also generates an SNMP trap for this event.)

Port <port-id> PD Denied power due to insufficient power allocation.

There is insufficient power available to power the PD on the indicated port and the port does not have sufficient PoE priority to take power from another active PoE port.

Port <port-id > PD Invalid Signature

The switch has detected a non-802.3af-compliant or non-

indication

802.3at-compliant device on the indicated port. This

 

message appears for all non-802.3af devices connected to

 

the port, such as other switches, PC-NICs, etc.

 

 

Port <port-id> PD MPS Absent indication

The switch no longer detects a device on < port-id >. The

 

device may have been disconnected, powered down, or

 

stopped functioning.

Port <port-id> PD Other Fault indication

There is a problem with the PSE connected to the port.

Port <port-id> PD Over Current

The PD connected to < port-id > has requested more than

indication

15.4 watts of power. This may indicate a short-circuit or

 

other problem in the PD.

50v Power Supply is faulted.

Internal power supply has faulted.

Failures:<num-failures>

 

50v Power Supply is OK. Failures:

Internal power supply is now OK.

<num-failures>

 

FET bad on port <port-id>

External FET (Field Effect Transistor) on the port has gone

 

bad and cannot deliver power.
