Custom & OEM →Who uses it, where it goes and how to plan the network
Written for the ZJIES6028M-HI-24GT4GB-DC from its own specifications: L3 managed 19-inch 1U rack switch, 24 × 10/100/1000Base-T copper plus 4 × 1000Base-X SFP, static/RIP/OSPF routing and VRRP v2, ZJRing <20ms, IEC61850-3, DC 100–240V input.
Who it is for
- Utilities and substations — IEC61850-3 compliance, EN61000-4 Level 3 immunity and a DC 100–240V wide-range input for station supplies; as the station-level switch it routes between bay, station and remote-access subnets.
- CCTV and ITS aggregation without a separate router — Put cameras, NVRs and operators in their own VLANs and let the switch route between them; PIM-DM/SM and IGMP move multicast video across subnets, and 4 SFP ports take field rings or remote sites over fibre.
- Mining, oil & gas and multi-site plants — Layer-3 routing (static, RIP v1/v2, OSPF) joins separate process, safety and video subnets across a site, VRRP v2 keeps the gateway alive if one core fails, and the DHCP server/relay hands out addresses per VLAN.
- System integrators and OEM projects — Web, Telnet, CLI and SNMP v1/v2/v3 management, configuration import/export for cloning many units, and project-level customization and OEM supported on this page.
Where and how to install
- Rack position and depth — It is a 19-inch 1U unit (440 × 44 × 310 mm), so check that the cabinet has at least 310 mm of usable depth plus room for cables at the front. The IP40 metal housing is for indoor cabinets and control rooms, not open outdoor mounting; support long, heavy cabinets with a rail or shelf under the switch.
- Power and alarm wiring — The 4-pin power terminal takes DC 100–240V wide-range, single or dual. For redundancy feed the two inputs from different sources (for example station DC and a UPS), each with its own breaker; the unit draws max 35 W. Wire the 2-pin alarm relay (220V, max 2A) to the RTU or alarm panel so a lost input is reported.
- Fibre and SFP handling — The 4 SFP slots come without modules. Use the same mode at both ends (multimode up to 2 km, single-mode for longer links), keep dust caps on until patching, clean connectors before plugging in and respect the bend radius in the cabinet. Copper ports stay within 100 m per run.
- Grounding and surge — Bond the chassis to the cabinet earth bar with a short conductor. EMS immunity is EN61000-4 Level 3, but copper cables that leave the building or cross a switchyard still need surge protectors at both ends; where possible use fibre for those links.
- First setup over the console — Before connecting it to the live network, configure it over the RJ45 console (RS-232, 9600bps, 8/N/1) or the web interface: management IP and VLAN, new login password, SNMP v3 instead of v1/v2, and the ring settings. Export the configuration file and keep it so a replacement unit can be loaded in minutes.
- Temperature and condensation — The standard version is rated -10~60°C and the wide-temperature version -40~75°C; order the wide-temperature version for unconditioned rooms and roadside or yard cabinets. Humidity is 5–95% non-condensing, so seal cable entries and use a cabinet heater or ventilation where nights are cold and humid.
Ports, routing and ring planning
Same 24 copper + 4 SFP layout as the Layer-2 ZJIES6028M-24GT4GB-DC, but with Layer-3 routing, a 16K MAC table (vs 8K) and a 12 Mbit buffer (vs 4 Mbit). It is 310 mm deep (vs 240 mm) and draws max 35 W. A typical split is 2 SFP for a field ring and 2 SFP for uplinks or a VRRP partner; there are no 10G ports on this model.

- Pick the ZJIES6028M-HI-24GT4GB-DC as the core or gateway of a site with several VLANs and gigabit fibre uplinks.
- Pick the Layer-2 ZJIES6028M-24GT4GB-DC for field or access nodes that do not route.
- Pick the ZJIES6028M-HI-24GT4S+ or ZJIES6028M-HI-24GT4GB4S+ when the uplink to servers or the core needs 10G.
All values are from this page's specification table. Camera bandwidth assumes 6 Mbps per 4 MP camera and is arithmetic, not a manufacturer figure; the ERPS recovery time and the maximum number of switches per ring are not listed on this page.
Layer-3 Industrial Switch FAQ — ZJIES6028M-HI-24GT4GB-DC
What routing protocols does the ZJIES6028M-HI-24GT4GB-DC support?
It is a full Layer-3 switch: IPv4 and IPv6 static routes, RIP v1/v2, OSPF for IPv4, VRRP v2 gateway redundancy with uplink backup, policy routing under IPv4/IPv6, and PIM-DM/PIM-SM multicast. BFD and NTP are also on board, so it can aggregate and route a large industrial network on its own.
How far can the fiber uplinks reach?
The switch has 4 × 1000Base-X SFP slots. With multimode modules you get 2 km; single-mode options cover 20, 40, 60 or 120 km, enough to link remote substations or plants over one pair of fibers. Note this model has no 10G uplink — all four slots are gigabit.
How fast does the ring recover after a link failure?
Ring redundancy uses STP/RSTP/MSTP, ERPS (ITU-T G.8032) and the ZJRing protocol, with self-healing under 20 ms on this model. That is fast enough that video streams and SCADA polling continue without visible interruption when a fiber segment in the ring is cut.
What power input does it take and where can it be installed?
It accepts DC 100–240V wide-range input and mounts in a standard 19-inch rack. The design is IEC61850-3 compliant with wide-temperature operation and strong EMC immunity, which is why it targets substation automation and other large-scale industrial networks rather than office wiring closets.
How do I manage and secure this switch?
Management runs over SNMP v1/v2/v3, Web, Telnet and a serial CLI (RS-232 RJ45 console, 9600 bps, 8/N/1). Security covers ACLs, port MAC filtering, MAC binding, 802.1X with RADIUS and DDoS self-defense. It supports port and 802.1Q VLANs — up to 64 VLANs (VID 1–4094) — backed by a 16K MAC table and 12 Mbit buffer.
Do I need the Layer-3 ZJIES6028M-HI-24GT4GB-DC, or is the Layer-2 ZJIES6028M-24GT4GB-DC enough?
Choose the HI model when the switch itself must route: between VLANs, to another site with static routes, RIP or OSPF, as a redundant VRRP v2 gateway, or as the DHCP server. If a separate router or firewall already does that and this switch only connects devices and rings, the Layer-2 ZJIES6028M-24GT4GB-DC with the same 24 copper + 4 SFP ports is enough. The HI version also has a larger 16K MAC table and 12 Mbit buffer, and is 310 mm deep instead of 240 mm.
How do I build a redundant gateway with two ZJIES6028M-HI-24GT4GB-DC switches using VRRP?
Configure the same VRRP v2 group and virtual IP on a VLAN interface of both switches; devices use the virtual IP as their gateway, one switch is master and the other takes over if it fails. Link the two switches to each other, for example over two SFP ports, and dual-home each access switch or ring to both, which the page describes as uplink backup over multiple links. Run VRRP per VLAN and test by powering off the master before go-live.
Can the ZJIES6028M-HI-24GT4GB-DC act as the DHCP server for cameras and PLCs in each VLAN?
Yes, DHCP server, relay and snooping are listed. You can let the switch hand out addresses, or relay requests to a central DHCP server, and use DHCP snooping with IP Source Guard to block rogue servers and spoofed addresses. For cameras, PLCs and IEDs most integrators still prefer fixed IPs or DHCP reservations, so the address never changes after a restart and the NVR or SCADA keeps finding the device.
Can multicast video cross VLANs on the ZJIES6028M-HI-24GT4GB-DC?
Yes. Besides IGMP Snooping v1/v2 (up to 256 groups) inside a VLAN, the switch lists Layer-3 IGMP and PIM-DM/PIM-SM, so a camera VLAN can send multicast streams to decoders or a video wall in another VLAN. Use PIM-SM with a defined rendezvous point on larger networks and PIM-DM only on small ones, and keep the 256-group limit in mind when every camera sends its own multicast group.
The ZJIES6028M-HI-24GT4GB-DC has no 10G ports: when should I pick a 10G HI model instead?
When the traffic through one uplink approaches 1 Gbps. At an assumed 6 Mbps per 4 MP camera, one gigabit link carries about 166 cameras at full load, and about 116 with 30% headroom; static LACP can bundle 2 to 4 SFP ports for more total bandwidth. Above that, or when storage servers need a 10G link, choose the ZJIES6028M-HI-24GT4S+ (4 × 10G SFP+) or the ZJIES6028M-HI-24GT4GB4S+ (4 × 1G SFP + 4 × 10G SFP+).
What power connector does the ZJIES6028M-HI-24GT4GB-DC 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-24GT4GB-DC for your order.
