Overview
The ZJIES3000D-24GT4GB is an industrial managed Gigabit Ethernet switch with 24 × 10/100/1000Base-T ports and 4 × 1000Base-X SFP fiber slots — the highest port count in the ZJIES3000D DIN-rail switch series. 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, well suited for building large fully-gigabit self-healing ring networks.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
High-Density CCTV & PLC Aggregation Uplink24 × 10/100/1000Base-T ports plus 4 × 1000Base-X SFP fiber slots make this the highest port-count model in the ZJIES3000D DIN-rail series, aggregating a large local camera or PLC cluster onto one switch before uplinking over fiber.
Factory Production-Line Ring NetworkSTP/RSTP/MSTP, ERPS (G.8032), and the private ZJRing protocol (self-healing <10ms) let all 24 copper ports and 4 fiber uplinks participate in a resilient managed ring for factory or campus production lines.
DIN-Rail Cabinet InstallationDIN-rail (or wall-mount) design with selectable DC 24V (12–36V) / DC 48V (36–56V) dual-redundant or AC 220V (100–240V) input fits directly inside a compact electrical cabinet alongside PLC and control gear.
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 while keeping all 28 ports online.
Tunnel & Substation M&E Redundant PowerDC 24V/48V dual-redundant power input plus reverse-polarity and overload protection keeps the switch running if one feed fails — suited to tunnel, substation, or other electromechanical rooms where a single power interruption cannot be tolerated.
Fanless Silent Equipment RoomFully fanless IP40 metal enclosure with passive convection cooling keeps all 24 copper ports and 4 SFP fiber slots running silently in noise-sensitive control rooms or monitoring centers, with no moving parts to fail.
Not a good fit if:
- Standard package does not include SFP optical transceiver modules — order separately to activate the 4 fiber ports.
- IP40 enclosure only — needs a cabinet or additional protection for direct outdoor rain/dust exposure.
- No PoE output on the 24 copper ports — for camera or AP power delivery over the same cable, choose a PoE-enabled model in this series.

Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES3000D-24GT4GB from the manufacturer's datasheet: managed Layer 2, 24 × 10/100/1000Base-T + 4 × 1000Base-X SFP slots, STP/RSTP/MSTP, ERPS (G.8032) and ZJRing (<10 ms), AC 220V or redundant DC 24V/48V, max. 20 W, 85 × 175 × 146 mm DIN-rail housing.
Who it is for
- Large local camera clusters — Car parks, logistics yards and campus buildings where 20 or more cameras end in one cabinet: 24 Gigabit copper ports take them all, plus an NVR, on one switch.
- Production lines with many Ethernet devices — PLCs, remote I/O, drives, HMIs and vision cameras share one ring node, separated by VLANs and prioritised with QoS (8 queues per port).
- Substations, tunnels and DC-powered rooms — -DCL (12–36V DC) and -DCH (36–56V DC) take two redundant feeds with reverse-polarity and overload protection, and the 2-pin alarm terminal reports a fault.
- Integrators replacing several small switches — One managed unit instead of three 8-port switches means one IP address, one SNMP target and one configuration file per cabinet, and fewer cascade links that can fail.
Where and how to install
- Rail space and cable management — The body is 85 mm wide, 175 mm high and 146 mm deep. With 24 patch leads, put a cable duct directly below, label every port and cable, and leave front depth for the leads and fiber jumpers. DIN rail is default, wall mount optional; IP40, so closed cabinet only.
- Power and alarm wiring — Max. 20 W is about 0.83 A at 24 V or 0.42 A at 48 V. Feed the two DC inputs of the 4-pin terminal from separate supplies or breakers (-AC takes 100–240V AC on one input), and wire the 2-pin alarm terminal to a PLC or RTU input.
- Keep the NVR close to its cameras — If the NVR sits in the same cabinet, connect it to a copper port so recording traffic stays inside the switch and does not load the ring; only live views and playback then cross the fiber.
- Configure the ring before closing it — Set IP, VLANs and ring ports through the Web page or the RS-232 console (RJ45, 9600 bps, 8/N/1) before plugging the last ring fiber; an unconfigured closed ring is a loop. SFP modules are not included; order matching pairs for both ends.
- Earthing, surge, heat and condensation — Bond cabinet and rail to earth and add Ethernet surge protectors on copper runs that leave the cabinet. Leave free space above and below the switch for air flow, use the wide-temperature grade (-40 to +75°C) in unheated cabinets, and keep humidity non-condensing (5–95%).
Ports & ring planning
A full node can take 23 cameras plus 1 NVR on copper, 2 SFP slots for the ring and 2 for spurs or an aggregated uplink. At an assumed 8 Mbps per camera, 23 cameras produce 184 Mbps; if all of it goes to a remote NVR it uses about a fifth of a 1000 Mbps ring link, so keep the NVR local when several such nodes share one ring.

- Pick this model when a cabinet has more than 16 copper devices; for 16 or fewer, the ZJIES3000D-16GT4GB is 20 mm narrower and draws max. 15 W.
- Use 2 SFP slots as an aggregated 2 Gbps uplink when the NVR or VMS server is in another room.
Values are from the manufacturer datasheet. Recovery time is given for ZJRing only, and no fiber reach is listed for this model; reach depends on the SFP modules ordered. Camera counts, 8 Mbps per camera, 2 Gbps (2 × 1000 Mbps) and DC current (20 W ÷ voltage) are planning assumptions and arithmetic.
24-Port Managed Industrial Switch FAQ — ZJIES3000D-24GT4GB
How many devices can I connect to the ZJIES3000D-24GT4GB?
It offers 24 x 10/100/1000Base-T copper ports for end devices plus 4 x 1000Base-X SFP fiber slots for uplinks — 28 gigabit ports, the highest count in the ZJIES3000D DIN-rail series. That covers a full cabinet of cameras, controllers or workstations from a single switch.
What is the power consumption and how is it powered?
Maximum consumption is 20 W for all 28 ports. Power comes from DC 24V (12-36V) or DC 48V (36-56V) dual redundant inputs on 4-pin terminals, or a single AC 220V input covering 100-240V, with reverse-polarity and overload protection and a 2-pin alarm terminal.
Can it build a self-healing fiber ring for large sites?
Yes — that is its intended role. STP/RSTP/MSTP, ERPS per ITU-T G.8032 and the ZJRing self-healing ring are supported, and the 4 SFP slots provide the fiber ports to close large gigabit rings while still leaving spare uplinks toward the core.
What management and traffic control features does it have?
Full management includes QoS (802.1p), 802.1Q VLAN, IGMP Snooping/GMRP multicast control, LACP port trunking, 802.1X authentication and LLDP. Administration runs over SNMP v1/v2/v3, web, Telnet or the RS-232 console at 9600 bps, with DHCP client and password login.
Is it rugged enough for outdoor cabinets and factories?
The wide-temperature version runs from -40 to +75 C (storage to +85 C) at 5-95% non-condensing humidity, on a DIN-rail mount. EMC immunity reaches EN61000-4 level 3 and the unit passes IEC60068 shock, free-fall and vibration tests, with CE, FCC and RoHS compliance.
Will the uplink of the ZJIES3000D-24GT4GB become a bottleneck with 24 cameras?
Not at normal CCTV bitrates. At an assumed 8 Mbps per camera, 24 cameras total 192 Mbps, under a fifth of one 1000 Mbps fiber uplink. If the cameras run high bitrates or the NVR is remote, aggregate 2 SFP links with static LACP for 2 Gbps, or put the NVR on a local copper port so recording never crosses the uplink.
How much heat does the ZJIES3000D-24GT4GB add to a closed cabinet?
At most 20 W, which ends up as heat inside the cabinet; add it to the other loads (power supplies, PoE injectors, NVR) when you size ventilation or a cabinet fan. The wide-temperature grade is rated for -40 to +75°C ambient, measured around the switch, so keep free space above and below it and avoid mounting it directly over a power supply.
How far can the fiber links of the ZJIES3000D-24GT4GB reach?
That depends on the SFP modules, which are not included; the datasheet for this model lists 1000Base-X SFP slots but no fixed reach. Choose multimode modules for short in-site links and single-mode for longer roadside or inter-building links, with the same type at both ends. Send us each link's length and fiber type and we quote matching modules.
Can I use the ZJIES3000D-24GT4GB in a ring with other brands' switches?
Use the standard protocols for a mixed ring: ERPS (ITU-T G.8032) or RSTP/MSTP, both listed. ZJRing is Zhongxin's private ring and needs ZJRing on every member; the <10 ms figure is stated for ZJRing only, with no time listed for ERPS or RSTP. Confirm the other brand's ERPS settings match and test a fiber pull before handover.
How do I troubleshoot a camera or PLC that keeps dropping on the ZJIES3000D-24GT4GB?
Check the port's link LED and the Syslog and RMON counters on the Web page first; enable SNTP so log times are correct. Then mirror that port (one-way or two-way port mirroring is listed) to a spare port and capture the traffic with a laptop. Repeated link drops usually point to the cable, the connector or the device's power rather than the switch.
What power connector does the ZJIES3000D-24GT4GB 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-24GT4GB for your order.
