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, but 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. Customers can choose to use GPEN21 to power optical module for uplink to provider, or to provide PoE to power Ethernet uplink to the provider (that uses our GPeR and/or netPower products). The GPEN unit 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.
