Overview
The ZJIES6028M-HI-24GT4GX series is an unmanaged DIN-rail switch with fiber uplinks, combining 6 × 10/100Base-T copper access ports with 4 × fixed 10/100/1000Base-FX Gigabit fiber ports (SC, ST or FC connector optional, single- or dual-fiber optional) in one compact unit. It is plug-and-play with no configuration required, uses store-and-forward switching, and ships in a compact IP40 metal enclosure (45×175×143 mm) for DIN-rail or wall mounting. Powered by AC 220V (100–240V) single input or DC 24V (12–36V) / 48V (36–56V) redundant dual input with reverse-polarity and overload protection, it operates from -40 to +75°C — suited for sites that need to aggregate several near-end copper links onto a long-haul Gigabit fiber uplink.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
DIN-Rail Cabinet Installation, Any Power TypeThree selectable power inputs — AC 220V (100–240V) single input, DC 24V (12–36V) redundant, or DC 48V (36–56V) redundant — and a compact 45×175×143 mm DIN-rail (or wall-mount) body fit directly into a standard electrical cabinet.
Long-Haul Fiber Backhaul for Roadside & Perimeter SitesThe 4 fixed 10/100/1000Base-FX Gigabit fiber ports (SC/ST/FC connector optional) reach up to 2 km over multimode or 20/40/60/120 km over single-mode, long enough to backhaul roadside or perimeter camera clusters to a control room.
Copper Access + Fiber Uplink AggregationThe 6 × 10/100Base-T copper ports collect traffic from local end devices while the 4 fixed Gigabit fiber ports carry it out over a long-distance fiber uplink — suited for sites mixing near-end copper drops with a fiber backbone.
Built-In Media Conversion — No Separate Converter NeededBecause the 4 fiber ports are factory-fixed (not SFP slots), with connector type (SC/ST/FC) and single-/dual-fiber preset at order, each port doubles as a copper-to-fiber media converter — saving a standalone converter at every copper/fiber junction point.
Extreme-Temperature Outdoor CabinetsA wide operating range of -40 to +75°C (-40 to +85°C storage) plus EN61000-4 Level 3 EMC immunity suit unheated roadside cabinets and unconditioned equipment rooms.
Redundant Power for Tunnel & Underground M&E RoomsThe DC 24V (12–36V) or DC 48V (36–56V) models take dual redundant input with reverse-polarity and overload protection, while an AC 220V single-input model is also available — matched to whichever supply is already run in tunnel or underground utility rooms.
Not a good fit if:
- Unmanaged switch — no VLAN, RSTP/MSTP ring redundancy, or web-based management; choose a managed model for segmented or ring-topology networks.
- No PoE output on any of the 6 copper ports — cameras, APs, or IP phones needing PoE power require an external injector or a PoE-capable switch.
- Fiber connector type (SC/ST/FC) and distance class (multimode/single-mode) are fixed at the factory per order — they cannot be swapped in the field the way SFP modules can.

Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES6028M-HI-24GT4GX from its datasheet: managed Layer 3 rack switch, 24 Gigabit copper ports, 4 combo ports (RJ45 or 1G SFP), ZJRing/ERPS ring, AC/DC 100–240V.
Who it is for
- Utilities and substations — IEC61850-3 compliant with Level 3 EMS immunity and AC/DC 100–240V input; a Layer 3 core for a station LAN where Gigabit fibre to the bays is enough and 10G is not needed.
- CCTV and access-control projects — 24 Gigabit copper ports for NVRs, servers and edge switches, plus 4 combo ports that become copper or fibre per port, so the same unit fits a site whether the remote buildings arrive on Cat6 or fibre.
- Factories, mining and oil & gas plants — 24 Gigabit copper ports for control-room PCs, servers and PLC gateways, 64 VLANs to keep OT, IT and video apart, ACL and 802.1X for access control, and a -40 to 75°C wide-temperature version.
- System integrators and OEM projects — A Layer 3 core in 1U for mid-size sites: static routes, RIPv1/v2, OSPF and VRRPv2, managed by Web, Telnet, console CLI and SNMPv1/v2/v3, without paying for 10G ports the project does not use.
Where and how to install
- 19-inch rack, 1U, with depth to spare — The body is 440 × 44 × 310 mm and mounts in a standard 19-inch rack, not on DIN rail. Allow extra depth behind it for the power and alarm terminals and in front for fibre patch cords with a gentle bend radius.
- Power: AC/DC 100–240V, order dual input for redundancy — Input is via a 4-pin power terminal; single or dual power supply is an ordering option, so specify dual if you want to feed it from two sources (for example UPS mains and the station DC system). Maximum consumption is 35 W.
- Wire the alarm relay and ground the chassis — Use the 2-pin alarm terminal (rated 220V, max 2A) to signal a power or link fault to the SCADA or a buzzer. Bond the chassis to the rack earth bar with a short conductor; the Level 3 surge and EFT immunity depends on a good earth.
- Combo ports: one medium per port — Each of the 4 combo ports is either a 10/100/1000Base-T RJ45 or a 1000Base-X SFP, not both at once, so label in the cabinet which side is in use. For fibre, both ends need the same fibre type (single-mode or multimode) and wavelength pair; keep dust caps on unused SFP cages.
- Temperature and condensation — The standard model runs at -10 to 60°C and the wide-temperature model at -40 to 75°C; choose the wide model for unconditioned shelters. Humidity must stay within 5–95% non-condensing, and the IP40 case is for indoor cabinets only, so use a heater or ventilation where dew forms.
- Plan management before go-live — Keep the RS-232 console (RJ45, 9600 bps, 8-N-1) cable in the cabinet for recovery, set a management VLAN, change the login password, and export the configuration file after commissioning so a replacement unit can be restored quickly.
Ports & ring planning
This is the all-Gigabit model of the series: up to 28 ports can be active (24 copper + 4 combo), and the 4 combo ports let you choose fibre or copper per port. There are no 10G slots, so each uplink runs at 1 Gbps, or up to 4 Gbps when 4 ports are bundled with LACP.

| Operating temperature | -10~60°C standard · -40~75°C wide |
| Housing / mounting | IP40 metal · 19-inch 1U rack |
- Pick this model when every link is Gigabit and you want the flexibility to run up to 4 links on fibre or copper.
- If storage or another core needs 10G, choose the ZJIES6028M-HI-24GT4S+ (4 × SFP+) or the ZJIES6028M-HI-24GT4GB4S+ (4 × SFP + 4 × SFP+).
- Need more than 4 fibre ports? The ZJIES6028M-HI-16GT8GB4S+ has 8 × 1G SFP plus 4 × 10G SFP+.
Values from the manufacturer's ZJIES6028M-HI series datasheet. The 4 Gbps figure is 4 bundled 1 Gbps ports (LACP allows 2 groups of up to 4 ports); fibre reach depends on the SFP modules fitted.
Layer 3 Combo-Uplink Switch FAQ — ZJIES6028M-HI-24GT4GX
How do the 4 combo uplink ports work?
Each of the 4 combo ports can be provisioned on site as either a 10/100/1000Base-T RJ45 copper port or a 1000Base-X SFP fiber port, selectable per port. You can commission the project on copper and migrate individual uplinks to fiber later without swapping the chassis. SFP modules are ordered separately.
What Layer 3 routing does the ZJIES6028M-HI-24GT4GX support?
Full Layer 3: static routing, RIPv1/v2 and OSPF for IPv4, IPv6 static routing, policy routing for both IPv4 and IPv6, VRRPv2 gateway redundancy, plus PIM-DM/PIM-SM and Layer 3 IGMP for routed multicast. DHCP server, relay and snooping are built in, so it can terminate routed uplinks without a separate router.
What ring redundancy is available for CCTV or industrial backbones?
Four mechanisms: proprietary ZJRing self-healing ring with recovery under 20 ms, ERPS (G.8032) Ethernet ring protection, classic STP/RSTP/MSTP spanning tree, and VRRP-based Ethernet ring protection recovering in under 200 ms. A failed fiber or copper link in the loop is bypassed fast enough that video and control traffic barely notice.
What security features protect the access ports?
Port-based 802.1X authentication, port and MAC filtering, MAC binding, ACLs, IP Source Guard (IPSG), ARP proxy and DHCP snooping. Combined with 64 VLAN groups (VID 1-4094) and broadcast storm suppression, you can lock each of the 24 Gigabit access ports to known devices and contain rogue traffic.
How is it managed and what are the table capacities?
Management is via serial CLI on the RS-232 console port (RJ45, 9600, 8, N, 1), Web, Telnet and SNMP v1/v2/v3, with LLDP, Syslog, RMON, SNTP and NTP. Capacity: 16K MAC addresses, 12 Mbit packet buffer, static LACP with 2 groups of up to 4 ports, IGMP Snooping for 256 groups, rate limiting at 64 Kbps granularity.
Is Gigabit enough, or should I choose a 10G model instead of the ZJIES6028M-HI-24GT4GX?
Add up the traffic that must cross the busiest link. Assuming 4 Mbps per 4 MP camera stream and about 70% planned load, one 1 Gbps link carries roughly 175 cameras, and an LACP bundle of 4 ports about 700. If a single NVR cluster, server or core link needs more than that, choose the ZJIES6028M-HI-24GT4S+ or ZJIES6028M-HI-24GT4GB4S+ with 10G SFP+ slots.
Which SFP modules fit the combo ports of the ZJIES6028M-HI-24GT4GX, and how far can they reach?
The SFP side of each combo port takes 1000Base-X (Gigabit) modules; 10G SFP+ modules will not run in it. Reach is set by the module: multimode for short runs inside a site, single-mode for long links between buildings or stations. The datasheet has no module compatibility list, so send us the fibre type, distance and far-end device and we will supply matched modules, in industrial temperature grade for the -40 to 75°C model.
Can the ZJIES6028M-HI-24GT4GX run from a 110V or 220V DC station supply?
The datasheet gives the input range as AC/DC 100–240V, so a 110V or 220V DC station supply falls inside it, as does normal AC mains. Order the dual-power version if you want one input from the DC system and one from AC, and wire the 2-pin alarm terminal so the loss of either input is reported. There is no 24V or 48V DC version of this model in the datasheet.
Does the ZJIES6028M-HI-24GT4GX keep IEC 61850 GOOSE and multicast video from flooding the network?
IGMP Snooping v1/v2 with up to 256 multicast groups stops multicast streams flooding every port, and PIM-DM/PIM-SM can route multicast between subnets. GOOSE frames are Layer 2 multicast, so keep them in their own VLAN and use 802.1p priority (4 priority queues with strict or weighted scheduling) to put them ahead of video. Broadcast, multicast and unknown-unicast storm suppression is also available to protect the network.
Can I use the ZJIES6028M-HI-24GT4GX as a core for edge switches spread across a site?
Yes. Copper links to nearby cabinets are limited to 100 m per run, so use the 4 combo ports with SFP modules for buildings farther away, and the remaining copper ports for local equipment. Put each area in its own VLAN (up to 64) and let the switch route between them with static routes or OSPF. The switch has no PoE, so cameras and access points are powered by PoE edge switches.
What power connector does the ZJIES6028M-HI-24GT4GX 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 ZJIES6028M-HI-24GT4GX for your order.
Can I order one unit first, and how does it reach my country?
Yes — a single sample can be ordered and sent by air. For larger orders we deliver EXW or FOB to your freight forwarder's warehouse in China, or arrange air or sea freight to your country on request. Every shipment comes with a commercial invoice and packing list for customs; import duties and VAT in your country are not included unless agreed in writing.
How do I pay?
