PoE Power Management

4.2.2 Configuring and Monitoring Ports
Use the PoE Port Configuration page. (Ports > Power Over Ethernet > PoE Port Config.) to configure
and monitor the PoE status for each port. The Port Configuration page displays the following:
• Port: The physical port number.
• PoE: Enables or disables power to the port. Set the Admin parameter to either On or Off. On
or Up means that the switch may supply power to the port, Off or Down means that the
switch will not supply power to the port under any circumstance. If PoE is On, the display
shows Up. If PoE is Off, the display shows Down. The default is Up.
• Status: The port’s power status. When a powered device is connected and enabled and the
ES3000 is currently providing power, Powered is displayed. Otherwise, Not Powered is
displayed.
• Class: The powered device’s classification. The powered device can inform the switch of its
maximum power consumption, called its classification. If the device has a classification, it
automatically informs the switch, which displays the information. The switch does not use
classification for any decision-making processes. However, the administrator can use this
information to set the power limit for a port using the Limit parameter. The display will show
“---” for a port which has no powered devices connected to it. If there is a PD connected to
the port, the default is class 0, or an unclassified PD. If the PD gives its classification, then
that classification is displayed. All Symbol Technology PoE Access Ports are currently
unclassified.
• Priority: The priority of a port. This value is only used when the power management method
is priority-based. See “Configuring the Switch Policy” on page 4. The Priority parameter can
be set to Critical, High, or Low. When two ports have the same priority level, the lower
numbered port has the higher priority. For example, if both ports 8 and 15 are set to High
priority, port 8 has higher priority than port 15. The default is Low.
