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.

This page covers both 24-port SKUs in the ZJIES6028M-P series: ZJIES6028M-P24PGT-AC (24 × PoE copper ports only, no fiber uplink) and ZJIES6028M-P24PGT4GB-AC (adds 4 × 1000Base-X SFP fiber slots for uplink). SFP slots do not include optical modules. Both share the same 24 × 10/100/1000Base-T PoE af/at ports (up to 30W each), AC220V power and a 370W total PoE budget. The primary model on this page is ZJIES6028M-P24PGT4GB-AC.

24-Port Industrial PoE Switch FAQ — ZJIES6028M-P-24PGT4GB-AC

How many cameras can I connect to the ZJIES6028M-P-24PGT4GB-AC?

All 24 gigabit ports supply 802.3af/at PoE with a 370 W total budget — roughly 15 W per port with all 24 loaded. Typical IP cameras draw 4–12 W, so a full 24-camera CCTV deployment fits the budget; any single port can push up to 30 W at 48V DC for PTZ domes.

What is the difference between the 24PGT4GB-AC and 24PGT-AC versions?

The fiber slots. The 24PGT4GB-AC carries up to 4 × 1000Base-X SFP slots for fiber uplinks or ring building; the 24PGT-AC has no SFP slots and offers copper ports only. Both share the same 24 PoE gigabit ports, 370 W budget and management feature set — choose by whether you need fiber.

Can it survive outdoor cabinets in extreme climates?

It is built for a -40 to +75°C operating range with wide-temperature components, IEC61850-3 compliance and strong EMC immunity — no air-conditioned room required. Redundant power input keeps the switch alive if one feed fails, which matters for roadside or plant cabinets.

Does it support ring topology for CCTV backbones?

Yes. Ring redundancy runs STP/RSTP/MSTP, ERPS (ITU-T G.8032) and the ZJRing self-healing protocol with recovery under 50 ms, so camera streams resume almost instantly after a cut. Storm suppression for broadcast, multicast and unknown-unicast traffic protects the ring from flooding.

What security and traffic controls are included?

ACLs filter packets at L2–L4; port MAC filtering, MAC binding, 802.1X with RADIUS and DDoS self-defense lock down access. Traffic tools include QoS with 802.1p/DSCP and 8 queues per port, IGMP Snooping v1/v2 up to 256 groups, port mirroring, and rate limiting from 64 Kbps, over an 8K MAC table with 4 Mbit buffer.
