NETGEAR 8800 User Manual stays in the fault state until you disable that port, or disconnect the attached PD, or reconfigure the operator limit to be high enough to satisfy the PD requirements. To display the status of PoE ports, including disconnected or faulted ports, use the following command: show inline-power info ports When a port is disconnected or otherwise moves into a fault state, SNMP generates an event (after you configure SNMP and a log message is created). Port Power Reset You can set ports to experience a power-down, discover, power-up cycle. On the NETGEAR 8800 PoE switches, this power-cycling occurs without returning the power to the slot's reserved power budget. This function allows you to reset PDs without losing their claim to the reserved power budget. To power cycle specified ports, use the following commands: reset inline-power ports Ports are immediately depowered and repowered, maintaining current power allocations on modular switches. PoE Usage Threshold The system generates an SNMP event when any slot or stand-alone switch has consumed a specified percentage of that slot's reserved power budget or of the entire power for the stand-alone switch. The default value is 70%; you can configure this threshold to generate events from 1% to 99% consumption of the reserved power budget. You can also configure the system to log an Event Management System (EMS) message when the usage threshold is crossed (see Chapter 8, Status Monitoring and Statistics for more information on EMS). On modular switches, this threshold percentage is set to be the same for each PoE slot; you cannot configure it differently for each PoE module. On modular switches, although the threshold percentage of measured to budgeted power applies to all PoE modules, the threshold measurement applies only to the percentage per slot of measured power to budgeted power use; it does not apply to the amount of power used switchwide. To configure the threshold percentage of budgeted power used on a slot or the total power on a stand-alone switch that causes the system to generate an SNMP event and EMS message, use the following command: configure inline-power usage-threshold To reset the threshold that causes the system to generate an SNMP event and EMS message per slot to 70% for measured power compared to budgeted power, use the following command: unconfigure inline-power usage-threshold Chapter 7.
