PoE and PoE+ Implementation
The following x310 series switches support PoE:
■
x310-26FP
■
x310-50FP
This section explains how to implement PoE on this switch.
Power Capacity
The following information is provided as a guide, and we recommend that you consult the
appropriate Installation Guide for your particular switch for more detailed information.
PoE Port Allocation and Distribution
The total power available for PoE is dependent on the capacity of the power supply. How
this power is distributed across the available PoE ports depends on the PoE configuration
applied to the switch, particularly how you set the
commands.
The x310-26FP and x310-50FP switches are both Layer 2 PoE+ Gigabit Ethernet switches
with SFP and SFP+ support.
Power threshold
The switch can be configured to send a Simple Network Management Protocol (SNMP)
trap to your management workstation and records an entry in the event log whenever the
total power requirements of the powered devices exceed the specified percentage of the
total maximum power available on the switch. With the default setting of 80% applied, the
switch sends an SNMP trap when the PoE devices require more than 80% of the maximum
available power on the switch.
To adjust the threshold, use the command:
For your management workstation to receive traps from your switches, you must
configure SNMP on the switch by specifying the IP address of the workstation. The
management workstation will also record an entry in the event log whenever power
consumption of the switch has returned to a value that is less than the power limit
threshold.
To set the SNMP traps (notifications) for PoE, use the command:
See
for information about configuring SNMP traps for
for command examples to configure SNMP traps
for PoE.
