Advanced capabilities

Detailed network functions stay available here without interrupting the main selection path.

DIP-switch modes

E extends a selected link up to 300m at 10Mbps while other ports retain 1000Mbps within 100m. V enables isolation and VLAN on ports 1–16. D enables PoE watchdog/self-healing on ports 1–16. Port priority is enabled by default.

PoE delivery

Ports 1–16 support IEEE 802.3af/at with default pins 1/2 (+) and 3/6 (−). The 30W figure is the per-port maximum; simultaneous output is limited by the 300W supply.

Uplinks and fiber

The two RJ45 uplinks auto-negotiate Gigabit Ethernet. The two SFP slots accept separately ordered modules; optical mode and reach depend on the selected module.

Installation and environment

Fanless desktop or 19-inch 1U installation. Operating humidity: 5–90%, non-condensing. Storage: −40°C to +75°C and 5–95% RH. IP30 enclosure with listed ESD and surge protection.
