Overview
The ZJIES3000D-P-8PGT-DCH is an industrial managed PoE Gigabit Ethernet switch with 8 × 10/100/1000Base-T ports supporting IEEE 802.3af/at PoE+, delivering up to 30W per port to power and network cameras, IP phones and wireless APs over a single cable. Full management is built in — QoS, VLAN, IGMP Snooping/GMRP, Port Trunking, SNMP v1/v2/v3 — together with RSTP/STP/MSTP/ERPS/ZJRing ring-redundancy protocols for higher network reliability and interoperability. Its wide-temperature, EMC-hardened DIN-rail design meets demanding industrial field conditions, ideal for building fully-gigabit PoE ring networks.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
Warehouse CCTV PoE Camera Networking8 × 10/100/1000Base-T ports each deliver IEEE 802.3af/at PoE up to 30W, powering and networking a full aisle of warehouse PoE CCTV cameras over the same Cat5e/6 cable — a PoE switch built for warehouse CCTV deployments.
Control-Cabinet DIN-Rail InstallationDefault DIN-rail mounting (wall-mount optional) with a DC 48V (36–56VDC) dual redundant power input on a 4-pin terminal fits directly into control-cabinet electrical enclosures alongside PLCs and relays.
Factory Production-Line Ring NetworkSupports RSTP/STP/MSTP, ERPS (ITU-T G.8032) and the proprietary ZJRing self-healing ring protocol with recovery under 50ms, keeping production-line Ethernet rings online through a single link failure.
Extreme-Temperature Outdoor CabinetAn optional wide-temperature build operates from -40 to +75°C with Level-3 EMC immunity (ESD/EFT/Surge), suited to outdoor PoE camera cabinets facing seasonal extremes.
Network Segmentation & Port Access ControlIEEE 802.1Q VLAN tagging (up to 4094 VLANs), ACL Layer2–4 filtering, port-based 802.1X authentication with RADIUS, and MAC address binding isolate PoE camera/AP traffic from other VLANs and block unauthorized devices.
Remote SNMP Management + Local Console DebugSNMP v1/v2/v3 with Web/Telnet management covers day-to-day remote monitoring, while the dedicated RS-232 Console port (RJ45, 9600bps 8-N-1) gives technicians direct local access for initial commissioning or when the network link is down.
Not a good fit if:
- Fixed 8 × PoE copper ports only — no SFP fiber uplink slots on this model; choose an SFP-equipped sibling model if a fiber uplink is required.
- Only a DC 48V (36–56VDC) redundant power input is listed for this model in the datasheet — no AC220V or DC24V variant appears.
- IP40 metal enclosure only — needs a cabinet or additional protection for direct outdoor rain/dust exposure.

Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES3000D-P-8PGT-DCH from its own specifications: managed Layer 2, 8 × Gigabit PoE 802.3af/at up to 30 W per port, no fiber ports, STP/RSTP/MSTP/ERPS/ZJRing, DC 48V (36–56 VDC) redundant input, -40 to +75°C.
Who it is for
- CCTV installers in warehouses and yards — 8 PoE+ ports at up to 30 W each power a row of IP cameras, including PTZ-lite or heater-equipped models, over the same Cat5e/6 cable that carries the video.
- Substations, telecom shelters and 48V DC sites — It runs directly from a 48V DC battery plant through two redundant inputs, so cameras, phones and access points stay powered from the site's own backed-up DC system.
- Factories and production lines — VLANs (up to 4094), 802.1X with RADIUS and MAC binding keep PoE cameras and wireless APs apart from PLC traffic, and RSTP/ERPS/ZJRing keep a copper ring of line cabinets running through one cable fault.
- Integrators with remote sites to monitor — SNMP v1/v2/v3, Syslog, RMON and a 2-pin alarm terminal report problems to the control room, and the RS-232 console lets a technician recover the switch on site when the network is down.
Where and how to install
- DIN rail in a closed cabinet — The housing is 70 × 175 × 150 mm and IP40, so plan about 70 mm of DIN rail (wall mounting optional) inside a closed cabinet. Outdoors, use a sealed pole or wall cabinet with cable glands at the bottom.
- 48V DC supply for PoE+ — Feed both inputs of the 4-pin terminal from separate supplies or breakers, each able to carry the full load alone. The page lists 36–56 VDC input, but 802.3at devices expect about 50–57 V at the port, so for 30 W ports use a supply set near the top of the range (for example 52–54 V) and confirm with us if your site voltage is lower.
- Camera cable runs and surge — Keep each PoE run under 100 m of solid-copper Cat5e or Cat6 (not CCA cable, which drops more voltage). Cameras on poles or outside walls should have an Ethernet surge protector at the cabinet end, bonded to the same earth bar as the switch.
- Heat inside the cabinet — Order the wide-temperature version (-40 to +75°C) for outdoor cabinets; the standard version is -10 to +60°C. With all ports near 30 W the switch handles a lot of power in a small fanless box, so leave space above and below it and shade the cabinet from direct sun. Humidity is 5–95% non-condensing; add a heater or filtered vent where nights are cold.
- Plan the uplink before you order — This model has no SFP ports: uplinks and ring links use copper ports, which costs camera ports and limits each hop to 100 m. If the cabinet is farther from the next switch or the NVR room, choose the ZJIES3000D-P-8PGT2GB-DCH or ZJIES3000D-P-8PGT4GB with SFP fiber ports.
PoE budget / how many cameras
The page gives 30 W per port and a maximum input of 5.1 A at 48 VDC (about 245 W) for 8 PoE ports, but no separate PoE budget figure. In practice the 8 ports, not the power, are the limit for ordinary cameras; the table shows the input current and supply size for three typical loads, if all 8 ports are used.
| 4 MP IR camera ≈ 6 W | PTZ-lite / AP ≈ 13 W | 30 W per port (max) | |
|---|---|---|---|
| Devices on the 8 PoE ports | 8 | 8 | 8 |
| Total PoE load | 48 W | 104 W | 240 W |
| Input current at 48 V (incl. 15 W switch) | ≈ 1.3 A | ≈ 2.5 A | 5.1 A (page max) |
| Supply per input (× 1.25 margin) | ≥ 1.6 A (≈ 80 W) | ≥ 3.1 A (≈ 150 W) | ≥ 6.4 A (≈ 310 W) |
| Uplink / ring ports | Copper only, 100 m | Copper only, 100 m | Copper only, 100 m |
- Ordinary 4 MP fixed cameras use only about 48 W in total on 8 ports, so a 48 V supply of about 80 W per input is enough.
- If any port feeds a PTZ, heater housing or 802.3at access point, size each supply for the 5.1 A maximum plus margin (about 310 W).
- Each copper port used for an uplink or ring link is one camera fewer: in a copper ring, 6 ports remain for cameras.
30 W per port, 5.1 A at 48 VDC and the 15 W switch consumption are from the page. 6 W and 13 W are assumed typical draws. Input current = (PoE load + 15 W) ÷ 48 V; supply = current × 1.25, rounded.
8-Port Industrial PoE Switch FAQ — ZJIES3000D-P-8PGT-DCH
How many IP cameras can the ZJIES3000D-P-8PGT-DCH power?
All 8 gigabit ports supply IEEE 802.3af/at PoE+ at up to 30 W each, with input current rated at 5.1 A on 48 VDC — roughly 245 W available. Typical IP cameras draw 4-12 W, so a full 8-camera setup fits easily, and one port can still feed a 30 W PTZ.
What power supply do I need for this PoE switch?
A 48 V DC source within the 36-56 VDC window, wired to the dual redundant 4-pin terminal. Size it for the 5.1 A maximum input current; the switch electronics themselves draw at most 15 W. Reverse-polarity and overload protection are built in.
Does it have fiber uplink ports?
No — this is the copper-only PoE model, with up to 8 x 10/100/1000Base-T RJ45 ports and no fiber slots. If your design needs SFP fiber uplinks alongside the same 8 PoE ports, the series also lists variants with 2 or 4 x 1000Base-X SFP slots.
Which PoE wiring standard does it use — will my cameras be compatible?
Power is injected as Endspan MDI Alternative A: V+ on pins 1 and 2, V- on pins 3 and 6, following IEEE 802.3af/at. Any standards-compliant af/at device — IP cameras, IP phones, wireless access points — negotiates power automatically over the same data cable.
Can I build a redundant ring with this PoE switch?
Yes. It supports RSTP, STP, MSTP, ERPS per ITU-T G.8032 and the ZJRing protocol over its copper ports, alongside full management: QoS, 802.1Q VLAN, IGMP Snooping/GMRP, LACP trunking, 802.1X and SNMP v1/v2/v3 via web, Telnet or RS-232 console.
Will it survive outdoor camera cabinets in extreme climates?
The wide-temperature version operates from -40 to +75 C, with storage to +85 C and 5-95% non-condensing humidity, mounted on a DIN rail inside the cabinet. EMC immunity meets EN61000-4 level 3 and the unit passes IEC60068 shock, free-fall and vibration testing.
Can I reboot a frozen camera by switching its PoE port off and on from the ZJIES3000D-P-8PGT-DCH web page?
The page does not list per-port PoE on/off control, PoE scheduling or automatic PD-alive detection among the software features, so do not count on remote power cycling without checking with us first. What is listed is Web, Telnet and serial CLI management, SNMP v1/v2/v3, Syslog and Ping detection, which tell you which port has lost its camera. If remote reboot is a project requirement, ask us before ordering.
How far can a PoE camera be from the ZJIES3000D-P-8PGT-DCH?
Up to 100 m per cable, which is the Ethernet limit for both data and PoE. Use solid-copper Cat5e or Cat6; copper-clad aluminium cable drops more voltage and can make 30 W devices restart under load. For a camera farther away, put a small PoE switch or a PoE extender in a cabinet near it, or bring fiber to that point with an SFP-equipped sibling such as the ZJIES3000D-P-8PGT2GB-DCH.
How do I keep cameras, IP phones and Wi-Fi access points separate on one ZJIES3000D-P-8PGT-DCH?
Put each device type in its own 802.1Q VLAN (up to 4094 are available) and tag them on the uplink; the management VLAN keeps the switch itself off the camera network. Use 802.1p/DSCP QoS to give voice traffic priority, since the switch maps them into 8 queues per port. Port-based 802.1X with RADIUS or MAC binding stops someone from unplugging a camera and plugging a laptop into that port.
Should I choose the managed ZJIES3000D-P-8PGT-DCH or the unmanaged ZJIES1000D-P-8PGT-DCH?
Choose the ZJIES3000D-P-8PGT-DCH when switches will be linked in a ring, when cameras must share the network with PLCs, phones or office devices in separate VLANs, or when the control room needs SNMP, Syslog and alarm reporting. An unmanaged switch has no ring protocol, so it can only be used in a chain or star, and closing a loop with it causes a broadcast storm. For a stand-alone cabinet of cameras feeding one NVR, the unmanaged model is usually enough.
Can I bundle two ports of the ZJIES3000D-P-8PGT-DCH for a faster uplink to the NVR?
Yes. It supports static link aggregation (LACP) with 2 groups of up to 4 ports each, so two copper ports can form a 2 × 1000 Mbps trunk to a core switch that supports the same. For cameras alone it is rarely needed: 6 cameras at an assumed 8 Mbps each total about 48 Mbps, far below one Gigabit port. Aggregation is more useful for redundancy of the uplink cable, at the cost of camera ports.
What power connector does the ZJIES3000D-P-8PGT-DCH 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 ZJIES3000D-P-8PGT-DCH for your order.
