How to use

Install the switch in a suitable location with adequate ventilation and connect it to the network fabric using uplink ports or the designated uplink interfaces. Connect powered devices to the PoE+ RJ-45 ports using standard Ethernet cabling. Configure VLANs, quality of service and PoE settings via Juniper management tools or the device management interface to match site policies. Monitor port status and power consumption to ensure that connected devices receive sufficient power under expected load.

Usage recommendations

Verify total available PoE budget before deploying multiple high-power devices to ensure the switch can supply required power simultaneously. Use appropriate surge protection and follow cabling best practices to maintain reliable connectivity and device operation.
