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.

Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES6028M-P-24PGT4GB-AC from its datasheet: managed Layer 2 rack PoE switch, 24 Gigabit PoE+ ports (30 W each), 4 × 1G SFP, ZJRing/ERPS ring, AC/DC 100–240V, -40 to 75°C.
Who it is for
- CCTV integrators: warehouses, campuses, car parks — 24 Gigabit PoE+ ports at up to 30 W each power a whole cabinet of cameras from one 1U unit, one cable per camera, with 4 × 1G SFP slots to send the video to the NVR room over fibre.
- Factories and production lines — ZJRing (self-healing under 50 ms), ERPS and STP/RSTP/MSTP keep a fibre ring of PoE switches running through one cable fault, and up to 4094 VLANs separate cameras, APs and production devices.
- Hotels, schools and offices with Wi-Fi and IP phones — The same PoE ports feed IP phones and wireless APs, and 802.1p/DSCP QoS with 7 priority queues can put voice ahead of video on the uplink.
- Cold and hot outdoor cabinets — Rated for -40 to 75°C operation in an IP40 metal case with reverse-polarity and overload protection, for roadside, pole-base and yard cabinets without air conditioning.
Where and how to install
- 19-inch rack, 1U, ventilated — The ZJIES6028M-P-24PGT4GB-AC is 440 × 44 × 240 mm and mounts in a standard 19-inch rack. A loaded PoE switch turns most of its power into heat inside the cabinet, so leave space above and below it and use a fan or filtered vents in closed outdoor cabinets.
- Power: AC/DC 100–240V, size the supply for the PoE load — Input is AC/DC 100–240V on a 4-pin terminal, with single or dual supply as an ordering option. The datasheet gives a maximum power consumption of 500 W, so size the supply circuit and any UPS for at least that, and order the dual-input version if two power sources are available.
- Wire the alarm relay and ground the chassis — Use the 2-pin alarm terminal (220V, max 2A) to report a power fault to a buzzer or the control system. Bond the chassis to the rack earth bar with a short conductor, and fit Ethernet surge protectors on camera cables that leave the building or run up poles.
- Camera cables: 100 m per run, then fibre — Keep each PoE copper run within 100 m on solid-copper Cat5e or Cat6; copper-clad aluminium cable drops voltage and can make PoE+ devices reboot. For groups of cameras farther away, use the SFP slots with fibre to a remote PoE switch.
- Temperature and condensation — Operating range is -40 to 75°C with 5–95% non-condensing humidity. The IP40 case is for indoor or cabinet use only: in outdoor enclosures add a sun shield and a heater or ventilation where dew forms.
- Commission over the console, then save the config — Keep the RS-232 console cable (RJ45, 9600 bps, 8-N-1) in the cabinet, set a management VLAN, change the login password and export the configuration file once the ring and VLANs work, so a replacement unit can be loaded quickly.
PoE budget: how many cameras
Each port gives up to 30 W. The datasheet states a maximum power consumption of 500 W for the switch but no separate PoE budget, so the table plans against the 370 W shown on our page, which keeps you on the safe side. With ordinary fixed cameras all 24 ports fill up well inside that; with PoE+ PTZ cameras plan about 14 at 25 W.
| ZJIES6028M-P-24PGT4GB-AC | |
|---|---|
| PoE ports | 24 × 10/100/1000Base-T, IEEE 802.3af/at |
| Per-port max | 30 W @ 48 VDC |
| Switch max power consumption | 500 W (datasheet; no separate PoE budget stated) |
| Planning budget used below | 370 W (conservative) |
| 4 MP IR cameras at 6 W each | 24 (144 W) — limited by ports |
| Cameras at 13 W each (PTZ-lite, heater) | 24 (312 W) |
| PoE+ PTZ cameras at 25 W each | 14 (350 W) |
| Mixed example | 20 × 6 W + 4 × 25 W = 220 W |
| Camera cable | 100 m max (Cat5e/Cat6 copper) |
| Uplinks | 4 × 1000Base-X SFP (modules not included) |
| Ring protocols | ZJRing (< 50 ms), ERPS G.8032, STP/RSTP/MSTP |
| Power input | AC/DC 100–240V, single or dual |
| Operating temperature | -40~75°C |
| Housing / mounting | IP40 metal · 19-inch 1U rack, 440 × 44 × 240 mm |
- Pick this model when one cabinet serves up to 24 ordinary cameras, phones or APs: 24 fixed cameras at 6 W use only 144 W.
- For a site with 16 or fewer devices, the ZJIES6028M-P-16PGT4GB-DC has 16 PoE ports with the same 4 SFP slots.
- With many PoE+ PTZ cameras, add up their maximum draws and keep the total under about 80% of the planning budget (about 296 W of 370 W).
Camera draws of 6 W, 13 W and 25 W at the switch port are planning assumptions, not measured values. Port, per-port and 500 W figures are from the manufacturer's ZJIES-P series datasheet; the 370 W planning budget is the figure on our page, pending confirmation.
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.
Can the ZJIES6028M-P-24PGT4GB-AC power a 60 W PTZ or a camera with a heater?
Only if the device needs 30 W or less at the port: the PoE ports follow IEEE 802.3af/at (PoE+) with up to 30 W each, and 802.3bt is not listed. A PTZ or heater camera rated above 30 W needs its own power supply or a high-power injector, with the switch port used for data only. Check the device's maximum draw with IR and heater on, not its typical figure.
What power supply and UPS do I need for the ZJIES6028M-P-24PGT4GB-AC?
It takes AC/DC 100–240V, so normal mains or a 110V or 220V DC station supply both fall inside the range; there is no 24V or 48V DC input. The datasheet gives a maximum consumption of 500 W, so plan the circuit and UPS for at least 500 W plus margin, and order the dual-input version to feed it from two sources. Wire the 2-pin alarm terminal (220V, max 2A) so a lost input is reported.
Is one 1G SFP uplink enough for 24 cameras on the ZJIES6028M-P-24PGT4GB-AC?
Yes, with plenty of margin. Assuming 4 Mbps per 4 MP camera stream, 24 cameras send about 96 Mbps, under 10% of a 1 Gbps fibre link. The extra SFP slots are better used to build a ring (two ports) or to bundle links with LACP (up to 5 groups of up to 8 ports) when several switches are chained toward the NVR room.
Does the ZJIES6028M-P-24PGT4GB-AC handle multicast cameras and video walls?
Yes, IGMP Snooping sends each multicast stream only to the ports that asked for it, but the datasheet limits it to 50 multicast groups. With one group per camera stream, that covers 24 cameras with main and sub streams in multicast (48 groups). For larger multicast designs, use unicast for some streams or confirm the limit with us before ordering.
Can the ZJIES6028M-P-24PGT4GB-AC route between camera and office VLANs?
No, it is a Layer 2 managed switch: it separates traffic into port or 802.1Q VLANs with a management VLAN, but routing between them needs a firewall or a Layer 3 core such as the ZJIES6028M-HI series. Carry all VLANs to that device as a trunk over one of the SFP uplinks.
What power connector does the ZJIES6028M-P-24PGT4GB-AC 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-P-24PGT4GB-AC for your order.
