Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES3000D-8GT from the manufacturer's datasheet: managed L2, 8 × Gigabit copper ports and no fiber, STP/RSTP/MSTP/ERPS/ZJRing rings, 10 W maximum, AC 220V or redundant DC 24V/48V, -40 to +75°C wide-temperature version.
Who it is for
- Machine builders and production lines — Control cabinets that sit within 100 m of each other: 8 Gigabit copper ports connect PLCs, HMIs, drives and cameras, and the cabinets can be joined in a copper ring with no fiber or SFP modules to buy.
- Plant rooms, tunnels and DC-powered sites — The -DCL (12–36 VDC) and -DCH (36–56 VDC) versions take two redundant inputs, and at 10 W maximum the switch adds very little load to a battery system.
- Edge switch on a fiber ring — Hang it off a port of a ZJIES3000D-8GT2GB or -8GT4GB ring node when one cabinet needs more copper ports; VLANs, QoS and SNMP stay the same across the network.
- Buildings and campus CCTV — Floor or riser cabinets within 100 m of each other; IGMP Snooping (256 groups) keeps multicast video to the ports that need it, and 4094 VLANs separate cameras from office traffic.
Where and how to install
- DIN rail inside a 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, leave room below the RJ45 ports for the cable bend and label which two ports form the ring.
- 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 10 W maximum it draws about 0.42 A at 24 V or 0.21 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.
- Copper ring links, earthing and surge — Every ring link is copper, so keep each hop under 100 m on Cat5e or Cat6, use shielded outdoor cable between buildings and add Ethernet surge protectors at both ends of any link that leaves a building. Bond the cabinets and DIN rails to earth; the switch's EN61000-4-5 Level 3 surge rating does not cover lightning on a long outdoor run.
- 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 and bring cables in from the bottom through sealed glands.
Power versions and copper ring planning
All three versions have the same 8 copper ports and software; only the power input differs. In a ring, 2 of the 8 ports carry the ring, leaving 6 for devices. Plan as if one link is broken: with 6 cameras per switch at an assumed 8 Mbps each, every node adds 48 Mbps, so about 14 nodes (84 cameras, 672 Mbps) stay under about 70% of a 1000 Mbps link, with no more than 100 m between neighbours.

| Operating temperature | -10~60°C or -40~75°C | -10~60°C or -40~75°C | -10~60°C or -40~75°C |
- Pick -DCH for a 48V DC battery system (36–56 VDC) and -DCL for a 24V DIN-rail supply or 12V/24V battery (12–36 VDC); both take two supplies for redundancy.
- Pick -AC where mains is the only supply; it has one input, so use a UPS for backup.
- Any hop over 100 m, between buildings with different earths, or along a road? Use the ZJIES3000D-8GT2GB (2 SFP) or ZJIES3000D-8GT4GB (4 SFP) for fiber links instead.
Ports, power ranges, 10 W, ring protocols, <50 ms (ZJRing) and temperature are from the manufacturer's datasheet. Current = 10 W ÷ voltage. 100 m is the standard copper Ethernet limit. Ring figures assume 8 Mbps per camera, 6 cameras per node and a 70% load ceiling; the datasheet gives no maximum node count per ring.
8-Port Gigabit DIN-Rail Switch FAQ — ZJIES3000D-8GT
How many ports does the ZJIES3000D-8GT have, and are any of them fiber?
It provides 8 x 10/100/1000Base-T gigabit copper RJ45 ports; the spec sheet lists no SFP fiber slots, making it the all-copper unit of this series. All ports run full gigabit with store-and-forward switching, an 8K MAC address table and a 4 Mbit packet buffer.
What power inputs can I use on site?
Three options are listed: dual-redundant DC 24V (12-36 VDC), dual-redundant DC 48V (36-56 VDC), or a single AC 220V input (100-240 VAC), all on 4-pin terminals. Maximum draw is only 10 W, with reverse-polarity and overload protection plus a 2-pin relay alarm terminal.
Can I build a redundant ring with this switch?
Yes. It supports STP, RSTP and MSTP spanning-tree plus ERPS ring protection per ITU-T G.8032, so you can close a loop of switches and the network recovers automatically if one link fails — the series is designed for fully gigabit self-healing ring networks.
What environmental conditions does it tolerate?
Operating range is -10 to +60 C standard or -40 to +75 C wide-temperature, storage -40 to +85 C, humidity 5-95% non-condensing. It passes EN61000-4-2/3/4/5/6/8 Level 3 EMC immunity and IEC60068-2 shock, free-fall and vibration tests, so it suits cabinets near motors and drives.
Is the ZJIES3000D-8GT a managed switch?
Yes — full management via SNMP v1/v2/v3, web, Telnet and a serial CLI console (RS-232, RJ45, 9600 bps). Features include QoS, port and 802.1Q VLANs up to 4094 IDs, IGMP Snooping, LACP port trunking, ACL L2-L4 filtering, 802.1X with RADIUS and DDoS self-defense.
How far apart can ZJIES3000D-8GT ring nodes be without fiber?
Up to 100 m per hop, because the ring runs over the copper ports and 100 m is the Ethernet limit for Cat5e/Cat6 copper. The switch has no SFP or fiber port, so there is no way to stretch a hop on this model. For longer hops, links between buildings or roadside runs, use the ZJIES3000D-8GT2GB or ZJIES3000D-8GT4GB, which have the same software plus SFP slots, and keep the 8GT for cabinets that are close together.
How many cameras or PLCs can a ring of ZJIES3000D-8GT switches handle?
Each switch keeps 6 ports for devices after 2 are used for the ring. For video, plan on one 1000 Mbps link carrying everything when the ring is broken: at an assumed 8 Mbps per 4 MP camera, 6 cameras add 48 Mbps per node, so about 14 nodes (84 cameras, 672 Mbps) stay under about 70% load. PLC and HMI traffic is tiny by comparison, so for control networks the port count, not the bandwidth, is the limit; give control traffic a higher QoS priority if cameras share the ring. The switch has no PoE, so cameras need local power or PoE injectors.
Do I need the managed ZJIES3000D-8GT or is the unmanaged ZJIES1000D-8GT enough?
Choose the managed 3000D-8GT if you need any of these: a self-healing ring (ERPS, ZJRing, RSTP/MSTP), VLANs to separate cameras, PLCs and office traffic, IGMP Snooping for multicast video, SNMP monitoring with an alarm terminal, or 802.1X/ACL security. An unmanaged switch has none of these, so a cabled loop between unmanaged switches causes a broadcast storm. For a single standalone cabinet with a few devices and no ring, the unmanaged ZJIES1000D-8GT is the simpler choice.
Can the ZJIES3000D-8GT 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.
How do I set up the ZJIES3000D-8GT 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.
What power connector does the ZJIES3000D-8GT 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-8GT for your order.
