Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Ports : the number and type of ports (RJ45, SFP, PoE) differ between models of a single series, which nevertheless shares one photo.
  • Antennas : their number, gain and whether they can be removed depend on the reference.
  • Modules and cables : SFP modules, transceivers, DAC cables, PoE injectors and rack-mounting kits are not included unless stated.
  • Power : some equipment is powered over PoE and shipped without a power adapter.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

Product overview

L2 managed industrial switch — 4 Gigabit PoE/PoE++ ports and 2 × 1G SFP uplinks — for harsh environments that demand reliability and remote power.
The NIS2100-4GT2SFP-HP operates from -40 °C to +75 °C in a fanless IP40 aluminium housing, mountable on a DIN rail or on a wall. Port 1 delivers up to 90 W (PoE++ 802.3bt), ports 2 to 4 provide 30 W each (PoE+ 802.3at); PoE budget of 108 W by default, adjustable up to 180 W.
Switching reaches 12 Gbps / 8.9 Mpps, with an 8,000-entry MAC table. Ring redundancy via ERPS (G.8032), zero-touch SON and Ruijie Cloud management. 6 kV surge protection, 15 kV (air) / 8 kV (contact) ESD protection.
Operating temperature: -40 °C / +75 °C — PoE budget: 108–180 W — Switching: 12 Gbps — Mounting: DIN rail / wall.

Frequently asked questions about this product

Can this industrial switch really withstand cold and heat?
From -40 to +75 °C in operation, fanless: the aluminium housing dissipates heat on its own. It tolerates 10 to 90% non-condensing humidity, salt corrosion and altitudes of up to 5,000 m — this is what sets it apart from an office switch.
How much PoE power does this industrial switch deliver?
One PoE++ port delivering up to 90 W — enough to power a motorised dome camera with a heater — and three PoE+ ports at 30 W. The total budget can be adjusted from the web interface: 108 W by default, 180 W maximum.
On which pairs does this switch deliver power?
Port 1 delivers power over all four pairs (1-2, 3-6, 4-5 and 7-8), as required by 90 W PoE++; ports 2 to 4 use the data pairs 1-2 and 3-6. Full four-pair cabling is therefore essential on the first port.
How is this switch powered on site?
With 46 to 57 V DC, at 4.2 A nominal, through a dual-input terminal block with power-loss alarm. It consumes less than 12 W without PoE load and less than 192 W at full load.
How is this switch mounted in an equipment cabinet?
On a DIN rail or on a wall, with the two brackets and the M3 screws supplied. The housing measures 50 × 155 × 130 mm and weighs 770 grams: it slips into a sealed cabinet, alongside the PLCs and power supplies.
What electrical protection does this industrial model offer?
6 kV common-mode on the network ports, 4 kV common-mode and 2 kV differential-mode on the power supply, with electrostatic immunity of 15 kV in air and 8 kV on contact. EMC compliance covers standards IEC/EN 61000-4-2 to 4-8.
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 ring along a production line or across a site. Loop prevention and port isolation round off the setup.
How many VLANs can you create on this switch?
Sixteen at most, chosen from the ID range 1 to 4094, as port-based VLANs. The MAC address table holds 8,000 entries and switching capacity reaches 12 Gbps, with jumbo frames of up to 10,000 bytes.
What happens if a powered camera stops responding?
The PoE watchdog power-cycles the port to bring it back up, and a PoE usage alarm flags abnormal consumption. On a remote site, this saves a trip for a simple restart.
How do you manage this switch on a remote site?
Through Ruijie Cloud or the Reyee app, with a self-organising network: the switch registers itself and is configured remotely. Cable testing and camera detection make troubleshooting easier without an on-site visit.
Is the switch new, and where can you find its datasheet?
Yes, new equipment, with the invoice serving as the warranty document. The manufacturer's document details the RG-NIS2100-4GT2SFP-HP, its protections and its environmental conditions: PDF datasheet.
