Chapter 14: Basic Administration Protocols
Power over Ethernet
If a device is connected to a low-priority port and causes the switch
•
to exceed its budget, power to this port is not turned on.
If a device is connected to a critical or high-priority port and would
•
cause the switch to exceed its power budget as determined during
bootup, power is provided to the port only if the switch can drop
power to one or more lower-priority ports and thereby remain
within its overall budget.
If a device is connected to a port after the switch has finished
•
booting up and would cause the switch to exceed its budget, power
will not be provided to that port regardless of its priority setting.
If priority is not set for any ports, and PoE consumption exceeds the
•
maximum power provided by the switch, power is shut down in the
following sequence:

ARAMETERS
These parameters are displayed:
Port – The port number on the switch.
•
Admin Status – Enables PoE power on a port. Power is automatically
•
supplied when a device is detected on a port, providing that the power
demanded does not exceed the switch or port power budget.
(Default: Enabled)
Mode – Shows whether or not PoE power is being supplied to a port.
•
Time Range Name – Name of a time range. If a time range is set,
•
then PoE will be provided to an interface during the specified period.
(Range: 1-16 characters)
Time Range Status – Indicates if a time range has been applied to an
•
interface, and whether it is currently active or inactive.
• Priority – Sets the power priority for a port. (Options: Low, High, or
Critical; Default: Low)
Power Allocation – Sets the power budget for a port.
•
(Range: 3000-34200 milliwatts; Default: 34200 milliwatts)
Power Consumption – Current power consumption on a port.
