Overview
The ZJIES3000D-8GT4GB is an industrial managed Gigabit DIN-rail Ethernet switch with 8 × 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 (RSTP/STP/MSTP/ERPS) that improve network reliability and interoperability. Its wide-temperature, EMC-hardened design is well suited for building fully-gigabit switching networks in demanding industrial field conditions.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
DIN-Rail Cabinet InstallationDIN-rail (or wall-mount) design fits directly inside a compact electrical cabinet, and three selectable power options — DC 24V (12–36V), DC 48V (36–56V) redundant input, or AC 220V (100–240V) — match whatever supply is already run to the panel.
Long-Haul Fiber Uplink for Roadside Sites4 × 1000Base-X SFP slots support multimode dual-fiber links up to 2 km or single-mode dual-fiber links up to 10 km (single- or dual-fiber SFP optional), long enough to backhaul roadside or perimeter camera points to a central room.
Factory Production-Line Ring NetworkManaged ring redundancy — STP/RSTP/MSTP, ERPS (ITU-T G.8032), and the private ZJRing protocol with self-healing under 10ms — keeps a factory or campus production-line network running through a single link failure.
Extreme-Temperature Outdoor CabinetThe wide-temperature build operates from -40 to +75°C with strong EMC immunity (EN61000-4-2/3/4/5/6/8 Level 3), suited to unheated outdoor cabinets facing seasonal extremes.
Redundant Power for Tunnel & Underground M&EDC 24V or DC 48V dual-redundant power input (AC 220V also available) with reverse-polarity and overload protection keeps the switch running if one feed fails — a fit for tunnel or underground mechanical & electrical rooms where a single power drop cannot take the network down.
Highest Fiber-Port Density in This 8-Port Family4 × 1000Base-X SFP slots is the most fiber uplinks offered on an 8-port ZJIES3000D switch (versus 0 on the plain 8GT and 2 on the 8GT2GB), letting one unit uplink toward up to four separate fiber directions instead of just one or two.
Not a good fit if:
- No PoE output on any port — cameras, APs, or IP phones needing PoE power require an external PoE injector or a PoE-enabled switch model.
- Standard package does not include SFP optical modules — order separately to activate the 4 fiber ports.
- IP40 enclosure only — needs a cabinet or additional protection for direct outdoor rain/dust exposure.

Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES3000D-8GT4GB from the manufacturer's datasheet: managed L2, 8 × Gigabit copper + 4 × 1000Base-X SFP slots, STP/RSTP/MSTP/ERPS rings plus ZJRing with <10 ms self-healing, 15 W maximum, AC 220V or redundant DC 24V/48V, -40 to +75°C wide-temperature version.
Who it is for
- CCTV hub cabinets — A cabinet that sits on the main fiber ring and also feeds side roads, gates or buildings: SFP 1–2 close the ring and SFP 3–4 run fiber spurs, while the 8 copper ports take local cameras.
- Tunnels and underground M&E rooms — -DCL (12–36 VDC) or -DCH (36–56 VDC) with two redundant inputs keeps the node up when one feed fails, and fiber in both directions along the tunnel avoids the 100 m copper limit.
- Factory and campus distribution — A production-line ring that must recover fast: the datasheet gives ZJRing self-healing under 10 ms on this model, and 4094 VLANs plus QoS keep each line's PLC traffic separate.
- Integrators who want spare fiber ports — With 4 SFP slots versus 2 on the ZJIES3000D-8GT2GB, a later extension to a new building or gate needs only an SFP module and a fiber, not a second switch in the cabinet.
Where and how to install
- DIN rail inside a sealed cabinet — The fanless metal housing is IP40, so outdoors it must sit inside a sealed cabinet. Mount it on the DIN rail (default) or the optional wall bracket, with the SFP ports facing the fiber splice tray and space below for the cable bend.
- Power wiring and redundancy — Order -AC for 100–240 VAC (single input), -DCL for 12–36 VDC or -DCH for 36–56 VDC. On DC versions feed both inputs of the 4-pin terminal from separate supplies or breakers. At 15 W maximum it draws about 0.63 A at 24 V or 0.31 A at 48 V.
- Plan the four fiber ports — Keep SFP 1 and SFP 2 as ring ports on every node, and use SFP 3 and SFP 4 for spurs or as a static LACP pair toward the core. Do not run a spur back into the ring at a second point unless that loop is covered by RSTP or the ring protocol, and label each fiber with its destination.
- Earthing, surge and copper runs — Bond the cabinet and DIN rail to earth. The switch is tested to EN61000-4-5 surge at Level 3, which does not cover a lightning hit on the pole: add Ethernet surge protectors on copper runs that leave the cabinet and keep each run under 100 m. Fiber between cabinets carries no surge.
- Temperature and condensation — There are two versions: standard -10~60°C and wide -40~75°C; specify the wide one for unheated outdoor cabinets. Humidity is 5–95% non-condensing, so add a filtered vent or small heater, bring cables in from the bottom and keep dust caps on unused SFP slots.
8GT, 8GT2GB or 8GT4GB: which 8-port model
All three have 8 Gigabit copper ports, the same management software and AC/DCL/DCH power versions; they differ in fiber ports. Spur traffic also crosses the ring: a hub with 8 local cameras and two spur cabinets of 8 cameras each, at an assumed 8 Mbps per camera, puts 192 Mbps on the ring, so about 3 such hubs (72 cameras, 576 Mbps) fit under about 70% of a 1000 Mbps ring link.

| Operating temperature | -10~60°C or -40~75°C | -10~60°C or -40~75°C | -10~60°C or -40~75°C |
- Pick the 8GT4GB for hub cabinets that close the ring and also feed one or two fiber spurs, or when you want spare fiber ports for later extensions.
- Pick the 8GT2GB for ordinary ring nodes with two fiber neighbours and nothing else to feed.
- Pick the 8GT when every hop is under 100 m of copper, for example cabinets in one hall.
All three columns are from the manufacturer's ZJIES3000D datasheets (ZJRing <10 ms is stated only for the 8GT4GB); fiber distances are from the ordering tables. Current = max. power ÷ 24 V. 192 Mbps = 3 cabinets × 8 cameras × 8 Mbps (assumption); 3 hubs × 192 = 576 Mbps, under 70% of 1000 Mbps.
Gigabit DIN-Rail Switch FAQ — ZJIES3000D-8GT4GB
What ports does the ZJIES3000D-8GT4GB provide?
It has 8 x 10/100/1000Base-T gigabit copper RJ45 ports and 4 x 1000Base-X SFP fiber slots. Switching is store-and-forward with an 8K MAC address table and 4 Mbit packet buffer, so all twelve interfaces can carry full gigabit traffic at the same time.
Why choose the version with 4 SFP slots?
Four 1000Base-X SFP slots let one cabinet uplink toward several fiber directions at once — for example two slots closing a ring and two more feeding branch cabinets. Copper field devices stay on the 8 RJ45 ports while all inter-cabinet links run on fiber.
How do I power the ZJIES3000D-8GT4GB?
Options are dual-redundant DC 24V (12-36 VDC), dual-redundant DC 48V (36-56 VDC) or single AC 220V (100-240 VAC), all via 4-pin terminals. Maximum consumption is 15 W, with reverse-polarity and overload protection and a 2-pin relay terminal for alarm signaling.
Which redundancy protocols keep the network alive?
The switch runs STP, RSTP and MSTP spanning-tree plus ERPS ring protection per ITU-T G.8032. Built into a fiber ring over the SFP slots, the network heals itself around a broken link, which is the intended design for gigabit industrial rings in this series.
What about temperature, EMC and management?
It operates at -10 to +60 C standard or -40 to +75 C wide-temperature with EN61000-4-2/3/4/5/6/8 Level 3 EMC immunity and IEC60068-2 shock and vibration tests. Management uses SNMP v1/v2/v3, web, Telnet or serial CLI, with QoS, 802.1Q VLAN, IGMP Snooping and LACP.
Can one ZJIES3000D-8GT4GB connect two separate rings through its four SFP ports?
Physically yes (SFP 1–2 for one ring, SFP 3–4 for the other), but the datasheet lists ERPS (G.8032) and ZJRing without stating how many ring instances, sub-rings or intersecting rings one switch supports. Do not design a tangent or intersecting ring on this model until we have confirmed it with the factory for your firmware. The safe uses of SFP 3–4 are open fiber spurs to remote cabinets or a static LACP pair toward the core.
What does the <10 ms ZJRing figure on the ZJIES3000D-8GT4GB mean in practice?
It is the self-healing time the datasheet gives for Zhongxin's ZJRing protocol on this model: when a fiber or node fails, traffic is switched to the other direction of the ring in under 10 ms, so video streams and most PLC connections ride through it. ZJRing works only between Zhongxin switches; in a ring with other brands use ERPS (G.8032) or RSTP, whose recovery time is not separately stated. The other ZJIES3000D models in this family are rated <50 ms for ZJRing, so plan a mixed ring on the <50 ms figure.
Can I bundle two fiber ports of the ZJIES3000D-8GT4GB for a faster uplink?
Yes. It supports static LACP with up to 2 aggregation groups of up to 4 ports each, so SFP 3 and SFP 4 can form one logical link of about 2 Gbps to a core switch that also supports LACP. Each single video stream still uses one 1 Gbps member, so the gain is in total capacity and in link redundancy if one fiber is cut. Use identical SFP modules and fiber on both members, and configure both ends before connecting the second fiber to avoid a temporary loop.
How many cameras can a ring built with ZJIES3000D-8GT4GB hub nodes carry?
Count the spurs as part of the ring load, and plan as if one ring link is broken so everything runs over a single 1000 Mbps link. At an assumed 8 Mbps per 4 MP camera, a hub with 8 local cameras plus two spur cabinets of 8 cameras each adds 192 Mbps, so about 3 such hubs (72 cameras, 576 Mbps) stay under about 70% load. Plain ring nodes with 8 cameras add 64 Mbps each. The datasheet gives no maximum node count per ring, so split very large sites into several rings.
Which SFP modules should I order for the ZJIES3000D-8GT4GB?
Use 1 Gigabit (1000Base-X) SFP modules; they are not included in the standard package. The ordering table lists multimode dual-fiber up to 2 km and single-mode dual-fiber up to 10 km, with single-fiber as an option. Both ends of a link must match: same fiber mode and speed, and for single-fiber a complementary transmit/receive pair. Support for 100 Mbps SFP modules is not listed, so tell us the far-end device and the distance and we will confirm the right pair before you order.
What power connector does the ZJIES3000D-8GT4GB 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-8GT4GB for your order.
