UPS PoE Switch Mission Critical is a PoE switch for a 19-inch rack with a built-in battery that keeps access points and cameras running during an outage.

Who it suits

Suits shops, offices, clinics and other businesses where a few key devices, such as access points, cameras and door access controllers, need to keep working for a while when the power goes out. The switch is installed in a rack or cabinet, and no separate UPS is needed for the devices on its PoE ports. How long the battery lasts depends on what is connected.

  • Has two AC outlets (230 V) on the back for devices such as a modem and a gateway.
  • The PoE budget is shared between the four PoE+ ports and the four PoE++ ports (up to 60 W per port). The ninth port is an uplink without PoE.
