Overview
The ZJIES3000D-16GT2GB is an industrial managed DIN-rail Ethernet switch offering 18 gigabit ports in total — 16 × 10/100/1000Base-T copper plus 2 × 1000Base-X fiber (pluggable SFP slots or fixed fiber). It provides full management — QoS, VLAN, IGMP Snooping/GMRP, Port Trunking, SNMP v1/v2/v3 — and multiple ring-redundancy protocols (STP/RSTP/MSTP/ERPS/ZJRing) with self-healing under 10 ms. Its wide-temperature, EMC-hardened design suits demanding industrial field conditions, ideal for high-port-density fully-gigabit self-healing ring networks.

Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES3000D-16GT2GB (and fixed-fiber -16GT2F) from the manufacturer's datasheet: managed Layer 2, 16 × 10/100/1000Base-T + 2 × 1000Base-X fiber, STP/RSTP/MSTP, ERPS (G.8032) and ZJRing (<10 ms), AC 220V or redundant DC 24V/48V, max. 15 W, 65 mm wide DIN-rail housing.
Who it is for
- Ring nodes with many local devices — The 2 fiber ports are exactly one ring in and one ring out, leaving all 16 Gigabit copper ports for cameras, PLCs, HMIs or an NVR at that node.
- Factories and process plants — VLANs, QoS by 802.1p/DSCP and IGMP Snooping keep PLC and SCADA traffic ahead of video on the same ring, and the 2-pin alarm terminal reports faults to the control system.
- CCTV integrators on campuses and car parks — One cabinet can collect 15 cameras plus a local NVR and pass the streams over a self-healing fiber ring to the control room.
- Utilities and tunnels on DC power — -DCL (12–36V DC) and -DCH (36–56V DC) take two redundant feeds with reverse-polarity and overload protection; the wide-temperature grade runs from -40 to +75°C.
Where and how to install
- Rail space for a 65 mm body — The housing is 65 × 175 × 150 mm (W × H × D). Leave rail space for it plus a cable duct for 16 patch leads, and enough cabinet depth for the leads and fiber jumpers in front. IP40: install inside a closed cabinet only.
- Power and alarm wiring — Max. 15 W is about 0.63 A at 24 V or 0.31 A at 48 V. Feed the two DC inputs from separate supplies or breakers, and wire the 2-pin alarm terminal to a PLC or RTU input.
- SFP or fixed fiber — On -16GT2GB the SFP modules are not included: order matching modules for both ends of each link. On -16GT2F the fiber ports are fixed, so the fiber type and connector must be chosen when ordering. Keep dust caps on until the jumper is plugged in.
- Commission the ring on the bench — Set the IP address, ring protocol and the two ring ports through the Web page or the RS-232 console (RJ45, 9600 bps, 8/N/1) before the last fiber is connected; an unconfigured closed ring is a loop. Export the configuration file and reuse it on the other nodes.
- Earthing, surge and climate — Bond the cabinet and rail to earth and fit Ethernet surge protectors on copper cables that leave the cabinet. Order the wide-temperature grade (-40 to +75°C) for unheated cabinets; the standard grade is -10 to +60°C. Keep humidity non-condensing (5–95%).
Ports & ring planning
Both versions are identical except for the fiber ports. With the 2 fiber ports used for the ring, each node has 16 copper ports: for example 15 cameras plus 1 NVR. At an assumed 8 Mbps per camera, a node adds 120 Mbps to the ring, so 8 such nodes (960 Mbps) would fill a 1000 Mbps ring link; plan for well below that.

- Pick -16GT2GB when distances or fiber types may change later, because modules can be swapped; pick -16GT2F when the fiber plant is known and you want no loose modules.
- Pick the ZJIES3000D-16GT4GB when a node needs fiber spurs or a second uplink besides the ring.
Values are from the manufacturer datasheet (ZJIES3000D-18 sheet). The datasheet gives a recovery time only for ZJRing and lists no fiber reach for this model; reach depends on the module or fixed-fiber option ordered. Camera counts, 8 Mbps per camera and DC current are planning assumptions and arithmetic.
16-Port Managed Industrial Switch FAQ — ZJIES3000D-16GT2GB
How many ports does the ZJIES3000D-16GT2GB have in total?
18 gigabit ports in total: 16 x 10/100/1000Base-T copper for end devices plus 2 x 1000Base-X fiber for uplinks or ring links. Store-and-forward switching with an 8K MAC table and 4 Mbit packet buffer handles high-port-density access in one DIN-rail unit.
What is the difference between the -16GT2GB and -16GT2F versions?
Both carry 16 gigabit copper ports and 2 x 1000Base-X fiber ports; the difference is the fiber interface. The -16GT2GB uses pluggable SFP slots so you pick the transceiver per distance, while the -16GT2F ships with fixed fiber ports. Choose SFP when link lengths vary across sites.
How fast does the ring recover after a cable break?
The switch runs STP/RSTP/MSTP, ERPS to ITU-T G.8032 and the ZJRing self-healing ring, with recovery in under 10 ms on a ring failure. For surveillance or PLC loops that means a broken fiber reroutes traffic before video streams or control sessions drop.
What management features are included?
Full L2 management: QoS with 802.1p class of service, 802.1Q VLAN, IGMP Snooping/GMRP for multicast, LACP port trunking, 802.1X authentication and LLDP. Access it via SNMP v1/v2/v3, web, Telnet or the RS-232 serial console at 9600 bps with login password protection.
What power supply and operating conditions does it need?
Feed it with DC 24V (12-36V) or DC 48V (36-56V) dual redundant inputs, or single AC 220V (100-240V); maximum consumption is 15 W and a 2-pin relay terminal reports alarms. The wide-temperature version works from -40 to +75 C at 5-95% non-condensing humidity.
The ZJIES3000D-16GT2GB has only 2 fiber ports. Is that enough for a ring and an uplink?
For a ring node, yes: the 2 fiber ports are the ring, and the control room is reached through the ring itself, where one node (or the core switch) sits in the same ring. If a node must also feed a remote cabinet over fiber, you have no third fiber port; use a copper port (up to 100 m) or choose the ZJIES3000D-16GT4GB, which has 4 SFP slots in the same 65 mm housing.
How many cameras can I put on a ring of ZJIES3000D-16GT2GB switches?
Bandwidth sets the limit, not ports. All streams travel over 1000 Mbps ring links; at an assumed 8 Mbps per camera, 60 cameras use 480 Mbps, about half of a link, which leaves headroom for a fiber break when traffic reroutes the long way round. With 15 cameras per node that is 4 nodes; with fewer cameras per node, more nodes fit. Send us camera count and bitrate and we check the design.
Can I mix the ZJIES3000D-16GT2GB with other brands' switches in one ring?
Only with a standard protocol: ERPS (ITU-T G.8032) or RSTP/MSTP. ZJRing is Zhongxin's private ring and works only between switches that run ZJRing, and the <10 ms recovery figure is given for ZJRing only. Check that the other brand supports the same ERPS version and settings, and test a fiber pull before handover.
How do I stop someone plugging an unknown device into a spare port of the ZJIES3000D-16GT2GB?
Use the listed security features: bind each camera's MAC address to its port or filter MACs per port, and where the devices support it, use 802.1X with a RADIUS server. Put unused ports in an empty VLAN and protect the Web, Telnet and console login with a password. This matters on roadside or car-park cabinets where 16 copper ports are within reach.
Should I choose the ZJIES3000D-16GT2GB or the ZJIES3000D-16GT4GB?
Both have 16 Gigabit copper ports, the same management and ring features, 15 W and a 65 × 175 × 150 mm housing. The ZJIES3000D-16GT2GB has 2 fiber ports, enough for a plain ring node, and is also available with fixed fiber (-16GT2F). The 16GT4GB has 4 SFP slots, for nodes that also need fiber spurs, a second ring or an aggregated fiber uplink.
What power connector does the ZJIES3000D-16GT2GB have, and do I need to confirm it before ordering?
Yes, please confirm the power connector with us before ordering. For Zhongxin Shutong products the power input type and connector can differ between versions and batches, so tell us your supply (AC or DC and the voltage), how you will wire it in the cabinet and your country's plug standard, and we confirm the exact connector and supply version of the ZJIES3000D-16GT2GB for your order.
