MikroTik GPEN21 smart power injector

The GPEN21 is a smart power injector that serves as an advanced software controlled repeater. Not only can it power your uplink devices via PoE, it can also provide a range of useful software features:

Interface management and monitoring
GPEN link fault detection
VLAN support
SNMP reporting
Basic traffic shaping

GPEN21 has an Ethernet and SFP port for fiber connectivity. The GPEN21 can be used to power optical module for uplink to provider, or to provide PoE to power Ethernet uplink to provider (that uses our GPeR and/or netPower products) The GPENunit can be securely attached to a wall or the communications cabinet. The Ethernet cable can be routed either directly through its bottom cable opening or into the wall, as preferred.
