Overview
The ZJIES3000D-16GT4GB is a managed DIN-rail industrial Ethernet switch with 16 × 10/100/1000Base-T ports and 4 × 1000Base-X SFP fiber slots. It offers full management — QoS, VLAN, IGMP Snooping/GMRP, Port Trunking, SNMP v1/v2/v3 — and multiple ring-redundancy protocols (STP/RSTP/MSTP/ERPS/ZJRing) for high reliability and interoperability. Its wide-temperature, EMC-hardened design meets demanding industrial field conditions, ideal for building fully-gigabit access-aggregation networks with fiber uplinks.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
Factory Production-Line Ring NetworkSupports STP/RSTP/MSTP, ERPS (G.8032) and the private ZJRing protocol with <10ms self-healing switchover for ring-topology factory networks.
Outdoor Extreme-Temperature CabinetRated for -40 ~ +75°C operating temperature (storage to -40 ~ +85°C) with an IP40 metal enclosure, built for unheated outdoor cabinets and cold climates.
Tunnel & Underground M&E Redundant PowerDCL/DCH variants take dual redundant DC inputs (12–36V or 36–56V) and meet EN61000-4-2/3/4/5/6/8 Level-3 EMC immunity for electromagnetically noisy tunnel and underground M&E rooms.
Roadside Monitoring Fiber Uplink4 × 1000Base-X SFP slots support multimode dual-fiber up to 2 km or single-mode dual-fiber up to 10 km, with single- or dual-fiber modules optional for long-haul roadside links.
High-Density Access Aggregation16 × 10/100/1000Base-T access ports plus 4 × SFP fiber uplinks let one switch aggregate a full camera or PLC segment and hand off over fiber to the core.
Mid-Size Ring/Star Backbone (25–50 Nodes)With 16 copper + 4 fiber ports, this model sits between the smaller 8/10-port and larger 24-port ZJIES3000D models — sized for mid-scale ring or star backbones of roughly 25–50 field nodes.
Not a good fit if:
- Layer-2 managed switch only — no Layer-3 routing or inter-VLAN routing; pair with a Layer-3 core switch if cross-subnet routing is required.
- No PoE output on any port — powered end devices (cameras, APs) need a separate PoE injector or PoE switch.
- IP40 enclosure only — not sealed against dust/washdown; mount inside a cabinet or enclosure for direct outdoor exposure.

Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES3000D-16GT4GB from the manufacturer's datasheet: managed Layer 2, 16 × 10/100/1000Base-T + 4 × 1000Base-X SFP slots (multimode 2 km / single-mode 10 km modules), STP/RSTP/MSTP, ERPS (G.8032) and ZJRing (<10 ms), AC 220V or redundant DC 24V/48V, max. 15 W.
Who it is for
- Aggregation cabinets in CCTV and ITS networks — 16 Gigabit copper ports collect the local cameras, and the 4 SFP slots carry the ring plus fiber spurs to nearby poles of up to 2 km (multimode) or 10 km (single-mode).
- Factory and process networks — QoS with 8 hardware queues per port, VLANs and storm suppression keep PLC and SCADA traffic stable when cameras share the same switch.
- Tunnels, substations and DC-powered rooms — -DCL (12–36V DC) and -DCH (36–56V DC) take two redundant feeds, EMS immunity is Level 3, and the 2-pin alarm terminal can signal a fault to the SCADA system.
- Integrators building mid-size rings — One model can be the ring node, the spur feeder and the uplink to the core, with config import/export to copy a tested setup to every cabinet; OEM and protocol-level customization are offered on the page.
Where and how to install
- Cabinet layout — The body is 65 × 175 × 150 mm (W × H × D), DIN rail by default or wall mount as an option. Put a fiber splice tray or patch panel next to it, a cable duct for 16 patch leads below, and keep it inside a closed cabinet because the housing is IP40.
- Power and alarm — Max. 15 W, about 0.63 A at 24 V or 0.31 A at 48 V. On -DCL/-DCH feed both inputs of the 4-pin terminal from separate supplies or breakers; -AC takes 100–240V AC on one input. Wire the 2-pin alarm terminal to a PLC or RTU input.
- Label and plan the 4 SFP slots — Decide before installation which slots are ring ports and which are spurs or uplinks, label both the slots and the fiber jumpers, and use the same slot numbers on every node so the configuration file can be reused. Modules are not included; keep dust caps on unused slots.
- Configure first, then close the ring — Set IP, VLANs and the ring through the Web page or RS-232 console (RJ45, 9600 bps, 8/N/1) before the last ring fiber is connected; a closed but unconfigured ring is a loop. Enable SNTP so Syslog entries carry the correct time for fault analysis.
- Earthing, surge and climate — Bond the cabinet and rail to earth and add Ethernet surge protectors on copper runs leaving the cabinet; fiber spurs need none and also isolate distant poles electrically. Use the wide-temperature grade (-40 to +75°C) in unheated cabinets and keep humidity non-condensing (5–95%).
Ports & ring planning
A typical node uses 2 SFP slots for the ring and 2 for fiber spurs to remote poles or for an aggregated uplink, with 16 copper ports for local devices. At an assumed 8 Mbps per camera, 16 local cameras add 128 Mbps; a 1000 Mbps ring link carries about 60 such cameras at half load (480 Mbps), leaving headroom when traffic reroutes after a fiber cut.

| Size (W × H × D) / housing | 65 × 175 × 150 mm / IP40 |
- Pick multimode modules for spurs up to 2 km inside a site, single-mode for roadside or inter-site links up to 10 km.
- Pick the ZJIES3000D-16GT2GB if the node only needs the 2 ring fibers, or the ZJIES3000D-24GT4GB if 16 copper ports are not enough.
Values are from the manufacturer datasheet. Recovery time is given for ZJRing only. Slot use, 8 Mbps per camera and DC current (15 W ÷ voltage) are planning assumptions and arithmetic.
16-Port Gigabit Industrial Switch FAQ — ZJIES3000D-16GT4GB
What ports and uplinks does the ZJIES3000D-16GT4GB offer?
It combines 16 x 10/100/1000Base-T copper ports with 4 x 1000Base-X SFP fiber slots — 20 gigabit ports on one DIN-rail unit. The four SFP uplinks let you aggregate the copper access ports toward several fiber directions, using store-and-forward switching with an 8K MAC table.
Why would I need 4 SFP fiber slots on an access switch?
Four fiber ports let one unit act as both access and aggregation: two ports close a redundant fiber ring while the other two uplink to a control room or branch to another cabinet. That is the layout the brief targets — fully-gigabit access-aggregation networks with fiber uplinks.
Which redundancy protocols keep the network alive?
STP, RSTP and MSTP spanning tree, ERPS ring protection per ITU-T G.8032, and the ZJRing self-healing ring are all supported. Combined with dual redundant DC power inputs and a relay alarm output, both the network path and the power feed have a backup.
How do I access and configure the switch?
Use the web interface, Telnet, SNMP v1/v2/v3 or the RS-232 serial console (RJ45, 9600 bps, 8/N/1). Configuration covers 802.1Q VLAN, QoS, IGMP Snooping/GMRP, LACP trunking, 802.1X authentication and LLDP, with standard MIBs including Bridge-MIB and VLAN-MIB for NMS platforms.
What are the power requirements and temperature range?
Power options are DC 24V (12-36V) or DC 48V (36-56V) with dual redundant 4-pin terminals, or single AC 220V spanning 100-240V; maximum draw is 15 W. The wide-temperature version operates from -40 to +75 C, with EN61000-4 level 3 EMC immunity for electrically noisy sites.
Can one ZJIES3000D-16GT4GB connect to two separate fiber rings?
Physically yes, it has 4 SFP slots, which is enough for two rings of 2 ports each. The datasheet does not state how many ERPS or ZJRing instances, or sub-rings, one unit can run, so send us the ring drawing and we confirm the configuration before you order. If one of the links is only a spur, no ring setting is needed on it.
How do I give PLC traffic priority over video on the ZJIES3000D-16GT4GB?
Put PLCs and cameras in separate VLANs, then map the control traffic to a higher class with 802.1p or DSCP; the switch has 4 priority classes with absolute or relative scheduling and 8 hardware queues per port. Limit any camera that bursts with ingress/egress rate limiting (steps from 64 Kbps), and enable IGMP Snooping if the video is multicast.
Which SFP modules do I need for the ZJIES3000D-16GT4GB?
Gigabit 1000Base-X SFP modules, ordered separately. The listed options are multimode dual-fiber up to 2 km and single-mode dual-fiber up to 10 km, with single-fiber modules also available. Choose by the fiber already installed and the longest link; single-fiber modules go in pairs with opposite wavelengths at each end. Give us each link's distance and fiber type and we supply matching pairs.
If a ZJIES3000D-16GT4GB fails in the field, how do I replace it quickly?
Export each node's configuration file after commissioning and keep it with the cabinet records. To replace a unit, import that file into a spare on a laptop, move the SFP modules to the same slots, and reconnect. While the unit is out, a ring keeps the other nodes online, and the 2-pin alarm terminal or SNMP shows which node dropped.
Should I choose the ZJIES3000D-16GT4GB or the ZJIES3000D-24GT4GB?
Both have 4 SFP slots and the same management and ring features. The ZJIES3000D-16GT4GB has 16 copper ports, max. 15 W and a 65 mm wide body; the 24GT4GB has 24 copper ports, max. 20 W and an 85 mm wide body. Choose by the number of local devices plus about 20% spare ports, and by the rail space you have.
What power connector does the ZJIES3000D-16GT4GB 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-16GT4GB for your order.
