GPEN21
Smart power injector that serves as an advanced software controlled repeater
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. Customers can choose to use GPEN21 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 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./

What happens if my device develops a fault during use?
Unlike third-party marketplaces, Apsardze24.lv provides a full 2-year warranty. We operate a local service center in Riga, ensuring that any technical issues are handled quickly by our specialized staff.
Does the GPEN21 come with a power supply unit included in the box?
No, the power supply unit (PSU) is not included. It accepts 12-57V power via the DC jack or PoE-in (802.3af/at or passive); if you are unsure which adapter to purchase, please contact our technical support at apsardze24@gmail.com.
Does this device run the full MikroTik RouterOS for complex routing tasks?
No, the GPEN21 uses a specialized management interface focused on interface monitoring and link management. It is designed for repeater and injector roles rather than as a primary high-performance router.
Is this the official EU version of the GPEN21 compatible with local updates?
Yes, Apsardze24.lv provides the official European version of the GPEN21. It is fully compatible with standard software updates and meets all EU regulatory requirements for networking equipment.
Can I use the MikroTik GPEN21 (GPEN21) to convert a fiber connection to Ethernet?
Yes, the device includes an SFP port for fiber connectivity and an Ethernet port for copper. This allows you to use it as a bridge to power an optical module for a fiber uplink to your service provider.
Is the MikroTik GPEN21 just a passive PoE injector or can it manage network traffic?
It is a smart, software-controlled device that functions as a managed repeater. It supports advanced features such as VLAN tagging, SNMP reporting, GPEN link fault detection, and basic traffic shaping, which standard injectors do not offer.
Can the GPEN21 be used to power other MikroTik devices like the GPeR or netPower?
Yes, the GPEN21 is specifically designed to provide PoE power to uplink devices. It is an ideal companion for the MikroTik GPeR (Gigabit Passive Ethernet Repeater) or netPower outdoor switches in provider-to-customer setups.

I bought the MikroTik GPEN21 from apsardze24.lv to power my uplink and utilize the SFP port. It works flawlessly as a smart injector, and the interface management is highly useful. The wall mounting is very neat too. Great service and super fast delivery from the shop!
