Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES6028M-P-16PGT4GB-DC from its specifications: managed Layer 2 rack PoE switch, 16 Gigabit PoE+ ports (30 W each, 370 W total), 4 × 1G SFP, ZJRing/ERPS ring, AC/DC 100–240V.
Who it is for
- CCTV integrators on industrial sites — 16 Gigabit PoE+ ports at up to 30 W each and a 370 W budget power a full camera group from one 1U unit, with 4 SFP slots to send the video to the control room over fibre.
- Utilities and substations — Listed as IEC61850-3 compliant with Level 3 EMS immunity and AC/DC 100–240V input, it can power cameras, IP phones and access points inside a station relay or communication room.
- Factories, ports and logistics yards — Ring redundancy with ZJRing (self-healing under 50 ms), ERPS and STP/RSTP/MSTP keeps camera and Wi-Fi traffic running through a single fibre cut, and VLANs separate cameras, APs and production devices.
- Projects with fewer, higher-power devices — With 370 W shared by 16 ports, 12 ports can run at the full 30 W at the same time, which suits PoE+ PTZ cameras and outdoor APs better than spreading the same budget over more ports.
Where and how to install
- 19-inch rack, 1U, ventilated — The ZJIES6028M-P-16PGT4GB-DC 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, single or dual as an ordering option. Plan the supply and any UPS for the whole load: up to 370 W of PoE plus up to 30 W for the switch itself is 400 W, so choose a UPS with margin above that and order dual input if two 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 — The standard version runs at -10 to 60°C and the wide-temperature version at -40 to 75°C, both at 5–95% non-condensing humidity; pick the wide version for unconditioned cabinets. The IP40 case is for indoor or cabinet use only, so 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, but all 16 ports share 370 W. With ordinary fixed cameras the 16 ports run out before the power does; with PoE+ PTZ cameras the budget is the limit, at about 14 cameras of 25 W.

|---|---|
| PoE ports | 16 × 10/100/1000Base-T, IEEE 802.3af/at |
| Per-port max / total PoE budget | 30 W / 370 W |
| Ports at full 30 W at the same time | 12 (360 W) |
| 4 MP IR cameras at 6 W each | 16 (96 W) — limited by ports |
| Cameras at 13 W each (PTZ-lite, heater) | 16 (208 W) |
| PoE+ PTZ cameras at 25 W each | 14 (350 W) |
| Mixed example | 12 × 6 W + 4 × 25 W = 172 W |
| Camera cable | 100 m max (Cat5e/Cat6 copper) |

| Operating temperature | -10~60°C standard · -40~75°C wide |
| Housing / mounting | IP40 metal · 19-inch 1U rack |
- Pick this model for up to 16 PoE devices, or when many of them are PoE+ (12 ports can run at 30 W together).
- Need more ports in the same 1U with 4 SFP slots? Look at the ZJIES6028M-P-24PGT4GB-AC with 24 PoE ports.
- Keep the total under about 80% of 370 W (about 296 W) to leave room for IR, heaters and PTZ movement peaks.
Camera draws of 6 W, 13 W and 25 W at the switch port are planning assumptions, not measured values; check each device's maximum PoE draw. Port and budget figures are from this model's page.
16-Port Industrial PoE Switch FAQ — ZJIES6028M-P-16PGT4GB-DC
How many IP cameras can the ZJIES6028M-P-16PGT4GB-DC power?
All 16 gigabit RJ45 ports are 802.3af/at PoE. The 370 W total budget averages about 23 W per port with every port loaded — typical IP cameras draw 4–12 W, so 16 cameras run comfortably. A single port can deliver up to 30 W at 48V DC for PTZ or heated housings.
How is PoE power delivered and what devices can it feed?
Power rides the data pairs as Endspan, MDI Alternative A: V+/V+/V-/V- on pins 1, 2, 3 and 6, at 48V DC up to 30 W per port. Compatible powered devices include IP cameras, IP phones and wireless APs — one Cat5e cable carries both data and power. The switch itself runs on AC 220V input.
Can I run a self-healing fiber ring with this switch?
Yes. It supports STP/RSTP/MSTP plus ERPS (ITU-T G.8032) and the ZJRing self-healing ring with recovery under 50 ms. The 4 × 1000Base-X SFP slots build the ring: multimode modules reach 2 km, single-mode options 20, 40, 60 or 120 km between nodes.
What management and VLAN features does it offer?
Full L2 management: SNMP v1/v2/v3, Web, Telnet and serial CLI, port and 802.1Q VLANs up to 4094 IDs, static LACP (2 groups of up to 4 ports), QoS with 802.1p/DSCP and 8 queues per port, port mirroring, IGMP Snooping v1/v2 for up to 256 multicast groups, and ingress/egress rate limiting from 64 Kbps.
Is it suitable for harsh electrical environments?
Yes — it is IEC61850-3 compliant with wide-temperature design and strong EMC immunity, built as a 19-inch rack unit for industrial sites. Security hardening includes L2–L4 ACL packet filtering, port MAC filtering, MAC binding, 802.1X with RADIUS, and DDoS self-defense, with an 8K MAC table and 4 Mbit packet buffer.
Can the ZJIES6028M-P-16PGT4GB-DC 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.
The ZJIES6028M-P-16PGT4GB-DC has -DC in its name: can I feed it from a DC station battery?
Our page lists the input as AC/DC 100–240V, single or dual, so a 110V or 220V DC station supply falls inside the range; a 24V or 48V DC battery does not. Because the name and the AC 220V wording in the ordering line differ, confirm the input version with us before ordering. Size the DC supply for about 400 W (370 W PoE plus 30 W for the switch).
Which SFP modules do I need for the ZJIES6028M-P-16PGT4GB-DC, and are they included?
The 4 slots take 1000Base-X (Gigabit) SFP modules, and modules are not included. Choose by distance: multimode modules reach 2 km, single-mode modules are offered for 20, 40, 60 or 120 km. Both ends of each link need matching speed, fibre type and wavelength pair, and for the -40 to 75°C version order industrial-temperature modules.
Should I choose the ZJIES6028M-P-16PGT4GB-DC or the 24-port ZJIES6028M-P-24PGT4GB-AC?
Both are 1U managed Layer 2 PoE+ rack switches with 4 × 1G SFP slots and AC/DC 100–240V input; the difference is 16 versus 24 PoE ports. Choose the 16-port model when the site has 16 or fewer PoE devices, or when many are PoE+ PTZ cameras that use the budget before the ports run out. Choose the 24-port model when you have more low-power cameras to connect at one cabinet.
Can the ZJIES6028M-P-16PGT4GB-DC route between VLANs?
No, it is a Layer 2 managed switch: it separates traffic into 802.1Q VLANs but does not route between them. Routing is done by a firewall or a Layer 3 core such as the ZJIES6028M-HI series, connected through one of the SFP uplinks as a trunk carrying all VLANs.
What power connector does the ZJIES6028M-P-16PGT4GB-DC 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-16PGT4GB-DC for your order.
