Total PoE budget up to 300 W
2 SFP 1 Gbps ports (fibre uplinks)
Extended temperature range -40 °C to +75 °C, IP40 aluminium housing
Fanless, DIN rail or wall mounting
ERPS ring redundancy (G.8032), self-organising network (SON)
Cloud-managed industrial switch — 8 Gigabit PoE/PoE++ ports and 2 × 1G SFP uplinks — for installations in harsh environments that need high-power PoE. The NIS2100-8GT2SFP-HP operates from -40 °C to +75 °C in a fanless IP40 aluminium enclosure that mounts on a DIN rail or on the wall. Port 1 delivers up to 90 W (PoE++ 802.3bt) and ports 2 to 8 supply 30 W each (PoE+ 802.3at), for a maximum PoE budget of 300 W. The 2 × 1G SFP ports serve as fibre uplinks. Switching capacity reaches 20 Gbps. 802.1Q VLAN, QoS, PoE watchdog and ERPS (G.8032) redundancy keep the service running. Zero-touch SON and Ruijie Cloud enable remote deployment and management. Operating temperature: -40 °C / +75 °C — Max PoE budget: 300 W — Switching: 20 Gbps — Mounting: DIN rail / wall.

Frequently asked questions about this product
How much PoE power does this industrial switch deliver?
One port in PoE++ up to 90 W and seven PoE+ ports at 30 W, for a total budget of up to 300 W. The 90 W port suits a heated motorised dome camera or a power-hungry outdoor access point.
Can this switch withstand extreme cold and heat?
From -40 °C to +75 °C, in an all-aluminium IP40-certified enclosure, with no fan. Surge tolerance reaches 6 kV and electrostatic immunity 15 kV (air) — the conditions of an industrial site or an outdoor cabinet.
What can be set using the switches on the enclosure?
Three functions without going through the interface: the ERPS ring, port isolation and the extended mode up to 200 m. A technician can therefore change a setting on site, even without access to the management network.
What happens if a link in the ring is cut?
The ERPS protocol, standardised as G.8032, switches over to the backup path. This is the classic topology of an industrial network, where switches are daisy-chained in a loop along a production line or across a site.
How is this switch mounted in a cabinet?
On a DIN rail or on the wall, with no fan or ventilation opening to keep an eye on. It slots in next to the PLCs and power supplies, in the existing technical cabinet.
How can this switch be managed at a remote site?
Through Ruijie Cloud — web interface, mobile app or MACC platform — with a self-organising network. PoE monitoring and automatic restart of devices save a trip for a frozen camera.
Is the switch new and covered by a warranty?
Yes, new equipment, with the invoice serving as the warranty document. This is the Reyee NIS2100-8GT2SFP-HP, a ten-port managed industrial switch, two of whose ports are 1 Gbps SFP fibre uplinks.
