Overview

The ZJIES6028M-24GT2GB-DC is an IEC61850-3 compliant industrial managed Layer-2 19-inch rack-mount gigabit switch with 24 × 10/100/1000Base-T copper ports and 2 × 1000Base-X SFP fiber slots. 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. Redundant power 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 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 queues by 802.1p or DSCP and 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.
