LABEL DESCRIPTION
PoE Mode Select the power management mode you want the Switch to use.
• Classification – Select this if you want the Switch to reserve the maximum power for each PD
according to the PD's power class and priority level. If the total power supply runs out, PDs
with lower priority do not get power to function. In this mode, the maximum power is reserved
based on what you configure in Max Power or the standard power limit for each class.
• Consumption – Select this if you want the Switch to supply the actual power that the PD
needs. The Switch also allocates power based on a port's Max Power and the PD's power
class and priority level. The Switch puts a limit on the maximum amount of power the PD can
request and use. In this mode, the default maximum power that can be delivered to the PD is
30 W (IEEE 802.3at Class 4) or 22 W (IEEE 802.3af Classes 0 to 3).
MIB Trap The Switch sends traps (monitoring event notification) to an SNMP (Simple Network Management
Protocol) manager when an event occurs.
Select ON to allow sending of MIB Trap when the following situations occur:
• Situation 1 –
Trap sent whenever a PoE port status change occurs (PoE port delivers power or delivers no
power to a PD (powered device)
• Situation 2 –
Trap sent in cases where the total power usage exceeds the PoE usage threshold
• Situation 3 –
Trap sent if total usage power decreases below the PoE usage threshold (only if previous total
power usage exceeded the PoE usage threshold and a trap was sent).
Note: If the MIB Trap is ON, you must also configure:
• SNMP trap destination (SYSTEM > SNMP > SNMP), SNMP trap group (SYSTEM > SNMP > SNMP
Trap Group) and SNMP trap port (SYSTEM > SNMP > SNMP Trap Port) for Situation 1
• SNMP trap destination and SNMP trap group for Situation 2 and Situation 3.
See Section 26.2 on page 157
PoE Usage Enter a number ranging from 1 to 99 to set the threshold. The Switch will generate a trap and/or
Threshold (%) log when the actual PoE usage is higher than the specified threshold.
Port This is the port index number.
