Configuration Guide Configuring PoE Configuration
By default, the DC mode is applied for disconnection detection.
For example, you can run the following commands in turn to set the disconnection detection mode to AC:
Ruijie# configure
Ruijie(config)# poe disconnect-mode ac
Ruijie(config)# end
Setting the Scheduled Power Disconnection of a PoE Port
You can configure a switch to supply or disconnect power on a certain port of the switch in a specific period of time. The
time period is specified by the time-range command in the global configuration mode. For details about the time-range
command, see related descriptions in ACL-SCG.doc. The scheduled power supply function of a PoE port supports a time
precision of 1 minute and 30 seconds.
Command
Function
Ruijie# configure
Enters the global configuration mode
Ruijie(config)# interface fastEthernet interface-id
Enters the interface configuration mode and specifies the
physical port to be configured
Ruijie(config-if)# poe power-off time-range
range-name
Specifies a time range in which the power supply on the port
will be on or off
Ruijie(config-if)# no poe power-off time-range
Disables the time-range-based power management function
For example, you can run the following commands in turn to enable the PoE function on port 1 of line card 1:
Ruijie# configure
Ruijie(config)# time-range poe-time
Ruijie(config-time-range)# periodic weekdays 8:30 to 17:30
Ruijie(config-time-range)# exit
Ruijie(config)# interface gigabitEthernet 1/1
Ruijie(config-if)# poe power-off time-range poe-time
Ruijie(config-if)# no poe enable
Ruijie(config-if)# end
 In the command for setting the scheduled power disconnection function on a PoE port, the range-name parameter is
a string of at most 32 characters.
Setting the Power Supply Priority of a PoE Port
You can set the power supply priority of ports on a PoE switch. The priorities are Critical, High, and Low in a descending
order. For a switch in auto or energy-saving mode, higher-priority ports first obtain power supply. If the power of the entire
PoE switch is insufficient to allow for all ports, lower-priority ports are powered off first. By default, the power supply
priority of a port is Low.
For ports with the same priority, a port with a smaller port number first obtains power. For example, port 1 has a priority
higher than ports 2 and 3.
For ports with the same priority, the installation of a new port will not affect the power supply to PDs already being
supplied with power. Ports with different priorities, however, are different. A port with a higher priority can preempt a port
with a lower priority.
