Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES3000D-8GT2GB from the manufacturer's datasheet: managed L2, 8 × Gigabit copper + 2 × 1000Base-X SFP slots, STP/RSTP/MSTP/ERPS/ZJRing rings, 15 W maximum, AC 220V or redundant DC 24V/48V, -40 to +75°C wide-temperature version.
Who it is for
- City, road and perimeter CCTV rings — The standard fiber-ring node: up to 8 cameras or devices per cabinet on Gigabit copper, and the 2 SFP ports run one fiber each way round the ring, so a cut fiber or a failed cabinet does not take the rest of the ring down.
- Traffic and ITS cabinets — Junction cabinets with a signal controller, detectors, an ANPR or speed camera and a few overview cameras; multimode SFP reaches 2 km and single-mode 10 km to the next junction.
- Substations, plants and pipelines — -DCH runs on a 48V DC battery system (36–56 VDC) with two redundant inputs, the 2-pin alarm terminal and SNMP traps report faults, and fiber between buildings avoids earth-potential problems on copper.
- Integrators upgrading unmanaged chains — Same 8 + 2 port layout as the unmanaged ZJIES1000D-8GT2GB, so an existing daisy chain can be closed into a ring by swapping the cabinet switches and adding one fiber from the last cabinet back to the control room.
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 ports before you terminate — Use SFP 1 and SFP 2 as the two ring ports on every node and the 8 copper ports for cameras and field devices. Put the NVR and VMS on the control-room node, use the same ring protocol on every node (with ERPS, exactly one RPL owner), and label each fiber with the cabinet it goes to.
- 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 8 + 2 port layout and software; only the power input differs. Plan the ring as if one link is broken and all traffic runs one way: with 8 cameras per switch at an assumed 8 Mbps each, every node adds 64 Mbps, so about 10 nodes (80 cameras, 640 Mbps) stay under about 70% of the 1000 Mbps fiber. For more cameras, build a second ring back to the control room.

| 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 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 two more fiber directions from one cabinet? Use the ZJIES3000D-8GT4GB.
Ports, power ranges, 15 W, ring protocols, <50 ms (ZJRing) and temperature are from the manufacturer's datasheet; fiber distances are from the ordering table. Current = 15 W ÷ voltage. Ring figures assume 8 Mbps per camera, 8 cameras per node and a 70% load ceiling; the datasheet gives no maximum node count per ring.
Gigabit DIN-Rail Switch FAQ — ZJIES3000D-8GT2GB
What is the port layout of the ZJIES3000D-8GT2GB?
It combines 8 x 10/100/1000Base-T gigabit copper RJ45 ports with 2 x 1000Base-X SFP fiber slots. Switching is store-and-forward with an 8K MAC address table and a 4 Mbit packet buffer, so all ten interfaces can run at full gigabit line rate.
What are the 2 SFP slots used for?
The two 1000Base-X SFP slots take gigabit fiber transceivers, typically used to uplink the switch over fiber or to close a fiber ring between cabinets. Copper devices connect on the 8 RJ45 ports while traffic leaves the cabinet on interference-free fiber.
Which power supplies does it accept?
You can feed it with dual-redundant DC 24V (12-36 VDC), dual-redundant DC 48V (36-56 VDC) or a single AC 220V input (100-240 VAC), each on a 4-pin terminal. Maximum consumption is 15 W, with reverse-polarity and overload protection and a 2-pin relay alarm output.
Does it support ring redundancy for critical networks?
Yes. STP, RSTP and MSTP spanning-tree plus ERPS per ITU-T G.8032 are supported, so several units can form a self-healing gigabit ring over the SFP fiber slots. If one segment is cut, traffic re-routes over the remaining path automatically.
What temperature range and management options does it offer?
It runs at -10 to +60 C standard or -40 to +75 C wide-temperature, with EN61000-4 Level 3 EMC immunity. Management covers SNMP v1/v2/v3, web, Telnet and serial CLI, plus QoS, 802.1Q VLAN, IGMP Snooping, LACP trunking and 802.1X authentication.
What do I gain with the managed ZJIES3000D-8GT2GB over the unmanaged ZJIES1000D-8GT2GB?
Mainly the ring: with ERPS, ZJRing or RSTP/MSTP the two fiber ports can form a closed self-healing ring, while an unmanaged chain must stay open and one cut fiber isolates every cabinet beyond it. You also get VLANs, QoS, IGMP Snooping for multicast video, SNMP v1/v2/v3 monitoring, an alarm terminal and 802.1X/ACL security. The port layout is the same 8 copper + 2 SFP, so cabinets and fiber can stay as they are. If the run is a short chain with no redundancy requirement, the unmanaged model is simpler.
Can the ZJIES3000D-8GT2GB power my IP cameras over PoE?
No. Its 8 copper ports are data-only; the 15 W maximum is the switch's own consumption, not a PoE budget. Power the cameras with local adapters or a PoE injector per camera, or choose the PoE sibling ZJIES3000D-P-8PGT2GB-DCH, which is listed as a managed industrial PoE DIN-rail switch with the same 8 + 2 idea; check its own page for the PoE budget and input voltage before you design.
How many cameras can a ring of ZJIES3000D-8GT2GB 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 8 cameras per switch, each node adds 64 Mbps, so about 10 nodes (80 cameras, 640 Mbps) keep that link under about 70% load. With higher bitrates or more cabinets, split the site into two or more rings that each close at the control room; the datasheet does not give a maximum number of nodes per ring.
Which SFP modules should I order for the ZJIES3000D-8GT2GB?
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.
Can the ZJIES3000D-8GT2GB 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.
What power connector does the ZJIES3000D-8GT2GB 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-8GT2GB for your order.
