Overview

The ZJIES6028M-24GT-DC is an IEC61850-3 compliant industrial managed Layer-2 19-inch rack-mount gigabit switch with 24 × 10/100/1000Base-T copper (RJ45) ports — a pure-copper, all-gigabit access switch with no fiber ports. It provides full management — QoS, VLAN, IGMP Snooping/GMRP, Port Trunking, SNMP v1/v2/v3 — and ring-redundancy protocols (STP/RSTP/MSTP/ERPS/ZJRing) with self-healing under 20 ms. AC 220V input, wide-temperature design and strong EMC immunity make it suitable for substation automation and demanding industrial sites. The ZJIES6028M series scales to 28 gigabit ports across many copper/fiber configurations.

Managed Industrial Rack Switch FAQ — ZJIES6028M-24GT-DC

What management features does the ZJIES6028M-24GT-DC support?

Full Layer-2 management: SNMP v1/v2/v3, web, Telnet and serial CLI (RS-232 RJ45, 9600 bps), port and 802.1Q VLANs up to 64 groups, QoS with 8 queues per port, IGMP Snooping for up to 256 multicast groups, LACP with 2 groups of up to 4 ports, port mirroring, Syslog, RMON and SNTP.

How fast does the ring recover after a link failure?

Three ring options are built in: standard STP/RSTP/MSTP, ERPS per ITU-T G.8032 with recovery under 50 ms, and the proprietary ZJRing self-healing ring that restores traffic in under 20 ms. For substation or process networks, that keeps video and SCADA sessions alive through a fiber cut.

Does this model have fiber ports?

No — the -24GT-DC is the pure-copper member of the family: 24 × 10/100/1000Base-T RJ45 gigabit ports and no fiber. The wider ZJIES6028M series scales to 28 gigabit ports across many copper/fiber configurations, so ask for the configuration matching your fiber uplink plan when requesting a quote.

Why does IEC61850-3 compliance matter?

IEC61850-3 is the environmental and EMC benchmark for communication equipment inside electrical substations. Compliance means this switch tolerates the interference, surges and temperature swings found next to switchgear, so integrators can bid it directly into substation automation and other demanding industrial projects.

What are the power supply options?

AC 220V input with a wide AC/DC 100–240V range, selectable as single or dual supply for redundancy, wired on a 4-pin power terminal plus a 2-pin alarm terminal. The alarm contact is rated 220V at up to 2A for signalling faults to the cabinet supervision loop.

How does it protect the network against attacks and storms?

Security tools include ACLs, port MAC filtering and binding, 802.1X port authentication with RADIUS, and DDoS self-defense. Broadcast, multicast and unknown-unicast storm suppression plus ingress/egress rate limiting from 64 Kbps keep a faulty device from flooding the whole industrial LAN.
