Overview

The ZJIES6028M-P-24PGT4GB-AC is an IEC61850-3 compliant industrial managed Layer-2 19-inch rack-mount full-gigabit PoE industrial Ethernet switch with 24 × 10/100/1000Base-T PoE ports (IEEE 802.3af/at) and up to 4 × 1000Base-X SFP fiber slots. Each PoE port delivers up to 30 W @ 48V DC with a 370 W total PoE budget, powering IP cameras, IP phones and wireless APs over a single cable. Full Layer-2 management (QoS, VLAN, IGMP Snooping/GMRP, SNMP v1/v2/v3) and ring redundancy (RSTP/STP/MSTP/ERPS/ZJRing) with self-healing under 50 ms, plus redundant power input and a -40~+75°C wide-temperature design, suit demanding industrial deployments.

Is This the Right Fit?

Six real deployment scenarios matched to this model's actual datasheet specifications.

Warehouse CCTV PoE Power & Networking24 × Gigabit PoE ports (802.3af/at, up to 30 W each) let a single 1U rack unit power and network an entire warehouse's worth of IP cameras — a true PoE switch for warehouse CCTV — over one cable per camera, no separate injectors needed.

19-Inch Rack Cabinet InstallationStandard 1U height and 440mm rack width (with 466/483mm mounting-ear span) let the switch mount directly into a 19-inch rack cabinet in an IP40 metal enclosure, alongside other rack-mount networking gear.

Severe Cold / Heat Outdoor Equipment CabinetThe wide-temperature design operates from -40 to +75°C with strong EMC immunity, suited to unheated outdoor cabinets and equipment rooms exposed to seasonal extremes.

Factory Production-Line Ring NetworkBuilt-in RSTP/STP/MSTP/ERPS/ZJRing redundant ring protocols recover a broken link in under 50 ms, keeping factory-floor ring networks running through a single cable fault.

IEC61850-3 Substation-Grade ComplianceCompliant with the IEC61850-3 standard for power-utility automation environments, the switch meets the EMC, vibration and temperature robustness bar that substation and switchgear-room network infrastructure requires.

24-Port High-Density PoE Aggregation + Optional 4-SFP Uplink24 PoE ports draw on a 370 W total PoE power budget to simultaneously feed a full rack's worth of PoE devices, while the 24PGT4GB-AC variant adds 4 × 1000Base-X SFP slots for a fiber uplink — the highest port-density rack-mount model in this PoE switch line.

Not a good fit if:

AC220V-powered SKUs only — no DC-input (24V/48V) variant is documented for this model in the datasheet.
IP40 enclosure only — needs a rack cabinet or additional protection for direct outdoor rain/dust exposure.
Layer-2 managed only — no Layer-3 routing or inter-VLAN routing capability is documented for this switch.
