Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES3000D-8GT8GB from the manufacturer's datasheet: managed Layer 2, 8 × Gigabit copper + 8 × 1000Base-X SFP slots, STP/RSTP/MSTP/ERPS and ZJRing (<10 ms), AC 220V or redundant DC 24V/48V, -40 to +75°C.
Who it is for
- Fiber hub cabinets on CCTV and ITS projects — With 8 SFP slots, one cabinet can terminate fiber runs from several remote poles or junction boxes and hand the traffic to the control room over the remaining fiber ports, while the 8 copper ports serve local cameras and devices.
- Substations, power plants and utilities — The -DCH version runs from a 48V DC station supply (36–56 VDC) with two redundant inputs, and the EMS tests are listed at Level 3 for ESD, surge and fast transients; fiber between buildings avoids ground-potential problems.
- Factories, mines and oil & gas sites — VLANs (up to 4094), 802.1p/DSCP QoS and ACL filtering keep PLC, SCADA and camera traffic apart on one fiber backbone, and the -40 to +75°C wide-temperature version suits unheated cabinets.
- System integrators building redundant rings — ZJRing heals in under 10 ms between Zhongxin switches, and standard ERPS (G.8032), RSTP and MSTP are there for rings or links that include other brands; SNMP v1/v2/v3, Syslog and the relay alarm let the control room see a broken link.
Where and how to install
- DIN rail in a sealed cabinet — The 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, about 50 mm of rail width, with the 8 SFP ports facing a fiber splice tray or patch panel and enough space for gentle fiber bends.
- SFP modules are ordered separately — The standard package does not include SFP optical modules. Choose 1000Base-X modules per link: multimode dual-fiber for up to 2 km, single-mode dual-fiber for up to 10 km, or single-fiber (BiDi) modules used as a matched pair at both ends. Keep dust caps on unused slots.
- Power wiring and alarm relay — 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 the 15 W maximum the switch draws about 0.63 A at 24 V or 0.31 A at 48 V. Wire the 2-pin relay terminal to the cabinet alarm input.
- Earthing, surge and copper runs — Bond the cabinet and DIN rail to earth. Keep each copper run under 100 m and fit Ethernet surge protectors on copper lines that leave the cabinet to another pole or building; use fiber for anything longer or between separately earthed sites.
- Temperature, condensation and airflow — Order the wide-temperature version (-40 to +75°C) for outdoor cabinets; the standard version is -10 to +60°C. Humidity is 5–95% non-condensing, so in cabinets with hot days and cold nights add a filtered vent or small heater and bring cables in from the bottom. The housing is fanless, so leave space above and below it.
Ports & ring planning: -AC, -DCL or -DCH
All three versions have the same 8 copper ports, 8 SFP slots and software; only the power input differs. In a ring, plan for the case where one fiber is cut and all traffic returns on one 1000 Mbps link: at an assumed 8 Mbps per 4 MP camera and a 70% load ceiling, one ring carries about 85 cameras.

- Pick -DCH for substations and telecom sites with a 48V DC battery system, -DCL for 24V DC control cabinets, and -AC only where mains is the only supply.
- Use 2 SFP slots for the ring and the other 6 for spur fibers to remote poles; or bundle up to 4 fiber ports in one aggregation group when a single 1000 Mbps link to the control room is not enough.
- Pick the ZJIES3000D-8GT2GB instead if a cabinet only needs the two ring fibers and no spur fibers.
Ports, power, protocols, aggregation, temperature and size are from the manufacturer's datasheet; reach is per module type (modules not included). Current = 15 W ÷ voltage. 85 cameras ≈ 70% × 1000 Mbps ÷ 8 Mbps per camera (assumption).
Fiber DIN-Rail Switch FAQ — ZJIES3000D-8GT8GB
What makes the ZJIES3000D-8GT8GB different from other models in the line?
Its port mix: 8 x 10/100/1000Base-T copper ports plus 8 x 1000Base-X SFP fiber slots on one DIN-rail unit — sixteen gigabit interfaces, half of them fiber. That suits sites where many fiber runs converge on a single cabinet while local devices stay on copper.
Can it aggregate several fiber links into one cabinet?
Yes — with 8 x 1000Base-X SFP slots it can terminate up to eight gigabit fiber links, for example runs arriving from separate buildings or along a corridor, while its 8 copper ports serve local equipment. LACP link aggregation and 802.1Q VLANs help organize that traffic.
What power inputs does the ZJIES3000D-8GT8GB take?
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. It draws at most 15 W and includes reverse-polarity and overload protection plus a 2-pin relay alarm terminal for fault reporting.
Does it support self-healing ring topologies?
Yes. STP, RSTP and MSTP spanning-tree plus ERPS per ITU-T G.8032 are built in, and the series is designed for fully gigabit self-healing rings. With eight SFP slots, one unit can even participate in more than one fiber ring or add spur links beyond the ring.
What environment and management features does it offer?
Operating range is -10 to +60 C standard or -40 to +75 C wide-temperature with EN61000-4 Level 3 EMC immunity and IEC60068-2 mechanical tests. Management runs over SNMP v1/v2/v3, web, Telnet and serial CLI, with QoS, 802.1Q VLAN, IGMP Snooping, LACP and 802.1X.
Which SFP modules can I put in the ZJIES3000D-8GT8GB, and does it take 100 Mbps or 10G modules?
The 8 slots are 1000Base-X SFP, so plan 1 Gigabit modules: multimode dual-fiber up to 2 km, single-mode dual-fiber up to 10 km, or single-fiber modules as a matched pair. 10G SFP+ modules will not work. The standards list includes 100Base-FX, but the ports are specified as 1000Base-X, so if the far end is a 100 Mbps fiber device confirm with us before ordering. Modules are not in the box; tell us the fiber type, distance and far-end equipment and we match them.
Can a ring of ZJIES3000D-8GT8GB switches include switches from other brands?
Yes, if every switch in that ring runs the same standard protocol: ERPS (ITU-T G.8032), RSTP or MSTP. ZJRing, the protocol with the <10 ms self-healing time, is Zhongxin's own ring and only works between Zhongxin switches. The datasheet does not give a recovery time for ERPS or RSTP, so if your project specifies one, ask us before ordering; test the mixed ring by pulling one fiber before handover.
How many IP cameras can I put on one fiber ring of ZJIES3000D-8GT8GB switches?
Size the ring for a fiber cut, when all video returns on one 1000 Mbps link. At an assumed 8 Mbps per 4 MP camera and a 70% load ceiling that is about 85 cameras per ring (700 ÷ 8 ≈ 87). Each switch adds up to 8 copper-connected cameras plus whatever arrives on its spur fibers. For more cameras, split them into two rings or use static link aggregation (2 groups × up to 4 ports) on the links to the control room.
How do I configure the ZJIES3000D-8GT8GB the first time?
You can use the web interface from a laptop on a copper port, Telnet, or the RS-232 console (RJ45 connector, 9600 bps, 8/N/1) with a console cable. Change the login password, set the management IP or DHCP client and a management VLAN, then configure the ring before you connect the second ring fiber, so no loop forms. Export the configuration file afterwards; it can be imported to the next switch, and firmware is upgraded by web or serial TFTP.
Will multicast camera streams flood every port of the ZJIES3000D-8GT8GB?
Not if IGMP Snooping is enabled: the switch then forwards each multicast group only to the ports that joined it, for up to 256 groups (IGMP v1/v2). You also need an IGMP querier somewhere in the network, usually the core switch or router. Broadcast, multicast and unknown-unicast storm suppression and per-port rate limiting (from 64 Kbps) add protection if a device misbehaves.
What power connector does the ZJIES3000D-8GT8GB 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-8GT8GB for your order.
