Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES3000D-4GT2GB from the manufacturer's datasheet: managed L2, 4 × Gigabit copper + 2 × 1000Base-X SFP slots, STP/RSTP/MSTP/ERPS/ZJRing rings, AC 220V or redundant DC 24V/48V, -40 to +75°C wide-temperature version.
Who it is for
- CCTV ring backbones on poles and small cabinets — A pole or cabinet with up to 4 cameras: the 4 Gigabit copper ports take the cameras and the 2 SFP ports go one way and the other round a fiber ring, so one cut fiber does not stop recording.
- Traffic, ITS and roadside cabinets — Signal controllers, detectors and a few cameras per junction; multimode SFP reaches 2 km and single-mode 10 km between cabinets, and the unit is only 47 mm wide on the DIN rail.
- Substations, utilities and DC-powered sites — The -DCH version runs from a 48V DC battery system (36–56 VDC) with two redundant inputs, and the 2-pin alarm terminal plus SNMP traps report faults to the SCADA or NMS.
- Factories and PLC cells — A small machine cell with a PLC, HMI and drives: 802.1Q VLANs keep control traffic apart from cameras or office PCs, and QoS with 8 queues per port gives control packets priority.
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.
- Use the alarm terminal — Wire the 2-pin alarm terminal to a PLC input, RTU or warning lamp so a fault is seen locally even when the network is down. The datasheet does not list which events trigger it; set the alarm conditions in the web interface and test by removing one power input.
- 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.
Power versions and ring planning
All three versions have the same 4 + 2 port layout and software; only the power input differs. In a ring, plan as if one link is broken and all traffic runs one way: with 4 cameras per switch at an assumed 8 Mbps each, every node adds 32 Mbps, so about 20 nodes (80 cameras, 640 Mbps) stay under about 70% of the 1000 Mbps fiber.

- Pick -DCH for substations, telecom rooms and any site with a 48V DC battery bank (36–56 VDC).
- Pick -DCL for cabinets with a 24V DIN-rail supply or a 12V/24V battery system (12–36 VDC), with two supplies for redundancy.
- Pick -AC only where mains is the one supply available: it has a single input, so a UPS is the backup. Need more than 4 copper ports per cabinet? Use the ZJIES3000D-8GT2GB with the same ring features.
Ports, power ranges, 15 W, ring protocols, <50 ms (ZJRing), temperature and size are from the manufacturer's datasheet; fiber distances are from the ordering table. Current = 15 W ÷ voltage. Ring figures assume 8 Mbps per camera, 4 cameras per node and a 70% load ceiling; the datasheet gives no maximum node count per ring.
4-Port Managed Industrial Switch FAQ — ZJIES3000D-4GT2GB
What ports does the ZJIES3000D-4GT2GB provide?
It has 4 x 10/100/1000Base-T copper ports for local devices and 2 x 1000Base-X SFP fiber slots for uplinks or ring links — six gigabit ports total. Store-and-forward switching, an 8K MAC table and a 4 Mbit packet buffer keep small field nodes running at full gigabit speed.
Where does a 4-port managed switch fit in a project?
It is sized for small field cabinets that only host a few devices — a camera pole, a gate controller or a remote sensor box — but still need to join a managed self-healing gigabit fiber ring. The two SFP ports connect it into the ring; the four copper ports serve the local gear.
Which ring redundancy protocols does it support?
It runs STP, RSTP and MSTP spanning tree plus ERPS Ethernet ring protection to ITU-T G.8032. With the two SFP fiber ports it joins redundant ring topologies, so a single fiber cut is bypassed and the devices behind the switch stay reachable.
Does the small model still get full management features?
Yes — the same management stack as the larger units: QoS (802.1p), 802.1Q VLAN, IGMP Snooping/GMRP, LACP trunking, 802.1X authentication and LLDP, reachable by SNMP v1/v2/v3, web, Telnet or RS-232 console at 9600 bps, protected by login password.
How is it powered and what conditions does it tolerate?
Power comes from DC 24V (12-36V) or DC 48V (36-56V) dual redundant 4-pin terminals, or single AC 220V (100-240V), drawing at most 15 W with a 2-pin relay alarm output. The wide-temperature version covers -40 to +75 C with EN61000-4 level 3 EMC immunity.
Can the ZJIES3000D-4GT2GB join an ERPS ring with switches from other brands?
Yes, use ERPS (ITU-T G.8032) or RSTP/MSTP for a mixed-brand ring, because these are standard protocols. ZJRing is Zhongxin's own protocol and only runs between Zhongxin switches; the <50 ms self-healing time in the datasheet is stated for ZJRing. For ERPS, every switch needs the same ring ID, control VLAN and ring ports, with exactly one RPL owner. Recovery time in a mixed ring depends on all devices, so unplug a ring link and check before handover; send us the other brand's model and we will check the settings with you.
Which SFP modules should I order for the ZJIES3000D-4GT2GB?
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.
How many cameras can a ring of ZJIES3000D-4GT2GB switches carry back to the NVR?
Plan for the worst case, when one ring link is broken and all video flows one way over a single 1000 Mbps link. At an assumed 8 Mbps per 4 MP camera and 4 cameras per switch, each node adds 32 Mbps, so about 20 nodes (80 cameras, 640 Mbps) keep that link under about 70% load. The datasheet does not give a maximum number of nodes per ring; for bigger sites build several rings that meet at the control room. The switch has no PoE, so the cameras need local power or PoE injectors.
How do I set up the ZJIES3000D-4GT2GB the first time and monitor it remotely?
Connect a console cable to the RJ45 console port (RS-232, 9600 bps, 8 data bits, no parity, 1 stop bit), or use the web interface or Telnet over the network; the default IP address and login are not on our page, so we send them with the order. For remote monitoring it supports SNMP v1/v2/v3 with traps, Syslog, RMON and LLDP, plus the 2-pin alarm terminal for a hard-wired alarm. After commissioning, export the configuration file so a spare unit can be loaded with the same settings, and set SNTP so log times are correct.
Will multicast video flood a network built with the ZJIES3000D-4GT2GB?
Not if IGMP Snooping is turned on: the switch supports IGMP Snooping v1/v2 with up to 256 multicast groups, so each stream only goes to ports that asked for it. Most NVRs pull unicast streams, so multicast matters mainly for video walls, decoders or several VMS clients watching the same camera. Also enable broadcast, multicast and unknown-unicast storm suppression on camera ports as a safety net. An IGMP querier function is not listed, so if the network has no router or core switch acting as querier, check the design with us first.
What power connector does the ZJIES3000D-4GT2GB 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-4GT2GB for your order.
