Set up PoE timer schedules
The switch lets you define multiple timer schedules that you can use for PoE power delivery
to attached PDs.
After you create a timer schedule, you can associate it with one or more PoE ports (see
Configure the PoE port settings on page 98). You can use a separate timer schedule for
each PoE port.
After you associate a timer schedule with a PoE port, the start date and time force the PoE
port to stop delivering power and the stop date and time enable the PoE port to start
delivering power.
You can create absolute schedules, which apply to specific dates and times, and you can
create recurring schedules.
Create a PoE timer schedule
The maximum number of timer schedules that you can add is 100.
To create a PoE timer schedule:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is of
f-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser
, enter the IP address of the switch.
