Custom & OEM →Who uses it, where it goes and how to plan the network
Written for the ZJIES6028M-24GT2GB-DC from its own specifications: L2 managed 19-inch 1U rack switch, 24 × 10/100/1000Base-T copper plus 2 × 1000Base-X SFP slots, ZJRing <20ms / ERPS <50ms, IEC61850-3, AC/DC 100–240V input.
Who it is for
- Utilities and substations — IEC61850-3 compliance, EN61000-4 Level 3 immunity and an AC/DC 100–240V input that suits station supplies make it a fit for substation automation LANs. The 2 SFP slots close a fibre ring between relay houses or bays, so yard links do not use copper.
- Traffic, tunnels and CCTV backbones — Equipment rooms along a road, tunnel or pipeline each get one switch: up to 24 cameras or controllers on copper, and the 2 SFP ports link the rooms in a ring that recovers in <20ms with ZJRing.
- Factories and PLC networks — Up to 64 VLANs keep PLC, HMI, camera and office traffic apart, and 802.1p/DSCP priority with 8 queues per port keeps control traffic ahead of video; storm suppression stops a looped or faulty device from flooding the line.
- 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 × 240 mm), so check that the cabinet has at least 240 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 AC/DC 100–240V, 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 30 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 2 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 and ring planning
Two SFP slots are exactly what one fibre ring needs: one slot towards each neighbour. That leaves the 24 copper ports for devices and for the uplink to the control room. Ring bandwidth is shared: all cameras in the ring use the same 1 Gbps, so at an assumed 6 Mbps per camera about 166 cameras fill it.

- Pick the ZJIES6028M-24GT2GB-DC for a single fibre ring where the control-room switch connects the NVR or SCADA server over copper.
- Pick the ZJIES6028M-24GT4GB-DC when you also need fibre uplinks, a second ring or a 2 Gbps aggregated link.
- Pick the copper-only ZJIES6028M-24GT-DC when all switches are within 100 m of each other.
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 maximum number of switches per ring is not listed, so ask us for large rings.
Managed Gigabit SFP Switch FAQ — ZJIES6028M-24GT2GB-DC
What ports does the ZJIES6028M-24GT2GB-DC provide?
24 × 10/100/1000Base-T gigabit copper ports for local devices plus 2 × 1000Base-X SFP slots for fiber uplinks, in a managed 19-inch rack chassis. Fiber optics are selectable: multimode for 2 km, or single-mode modules for 20, 40, 60 or 120 km runs.
Can I build a self-healing fiber ring with it?
Yes. The 2 SFP ports let each switch join a fiber ring, protected by STP/RSTP/MSTP, ERPS per ITU-T G.8032 recovering under 50 ms, or the proprietary ZJRing self-healing ring under 20 ms. A cable cut anywhere on the ring reroutes traffic before video streams or SCADA polls time out.
How do I manage and monitor it remotely?
Via SNMP v1/v2/v3 with standard MIBs (MIB-II, Bridge-MIB, VLAN-MIB, RSTP-MIB, LLDP-MIB), a web interface, Telnet or the RS-232 console at 9600 bps. Syslog, RMON, LLDP and SNTP give your NMS events, statistics, topology and synchronized timestamps; firmware updates load over web or serial TFTP.
What VLAN and QoS capacity should I plan around?
Up to 64 VLANs (port-based or 802.1Q, VID 1–4094) plus a dedicated management VLAN. QoS offers 4 priority classes mapped by 802.1p or DSCP into 8 queues per port, and IGMP Snooping v1/v2 handles up to 256 multicast groups — enough to separate video, control and office traffic on one industrial backbone.
Does it support redundant power?
Yes — the AC/DC 100–240V wide-range input can be ordered as single or dual supply, wired on a 4-pin power terminal with a separate 2-pin alarm terminal. With dual feeds from different sources, one supply failure neither drops the 24 access ports nor breaks the fiber ring.
Which projects is this switch aimed at?
It is IEC61850-3 compliant, so the primary target is substation automation, plus other demanding industrial sites that need a managed gigabit backbone: wide-temperature operation, strong EMC immunity, 802.1X/RADIUS security with DDoS self-defense, and DHCP client support for integration into existing addressing plans.
Which SFP modules should I order for the 2 slots of the ZJIES6028M-24GT2GB-DC?
Modules are not included. The slots are 1000Base-X, so use gigabit SFP modules: multimode for links up to 2 km, single-mode for 20, 40, 60 or 120 km. Both ends of a link must match (same mode and wavelength, or a matched A/B pair for single-fibre modules), and a dual-fibre module needs two cores per link. Tell us the length of each link and whether you have spare cores, and we will quote matching modules with the switch.
If both SFP slots of the ZJIES6028M-24GT2GB-DC are used for the ring, how do I connect the control room?
Only the switch that sits in the control room needs the uplink, and it uses one of its 24 copper ports to reach the NVR, SCADA server or core switch within 100 m. If the core is farther away or must also be on fibre, choose the ZJIES6028M-24GT4GB-DC, whose 4 SFP slots give two ring ports plus two fibre uplinks. Do not connect a second copper path between ring members, or you create a loop outside the ring protocol.
How many cameras can a fibre ring of ZJIES6028M-24GT2GB-DC switches carry?
All cameras in the ring share one 1 Gbps ring link towards the control room. At an assumed 6 Mbps per 4 MP camera, 1000 ÷ 6 ≈ 166 cameras fill it; keep about 30% headroom for bursts and plan roughly 116 cameras in total, for example 5 switches with 23 cameras each. The maximum number of switches per ring is not listed, so send us your node count for large rings. With ZJRing the ring recovers in <20ms after a fibre cut, with ERPS in <50ms.
The name ends in -DC: can the ZJIES6028M-24GT2GB-DC run from a 110 V or 220 V DC station battery, or from 24/48 V DC?
The page lists the input as AC 220V with a range of AC/DC 100–240V, single or dual. Nominal 110 V DC and 220 V DC station supplies are inside that range; 24 V and 48 V DC are not, so it cannot run from a 24/48 V DC panel supply. A 220 V battery on float or boost charge can rise above 240 V, so check your system's maximum voltage and tell us before ordering. The input has reverse-polarity and overload protection.
Can the ZJIES6028M-24GT2GB-DC join an existing ring built with another brand's switches?
Use a standard protocol for that: the switch supports ERPS (ITU-T G.8032, self-healing <50ms) and STP/RSTP/MSTP, which are meant to work between vendors. ZJRing (<20ms) is Zhongxin's own ring and only runs between Zhongxin switches. With ERPS, set the same ring ID, control VLAN and RPL owner on every node and test a fibre pull before commissioning; send us the other brand and model and we will check with the factory.
What power connector does the ZJIES6028M-24GT2GB-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-24GT2GB-DC for your order.
