Overview

The ZJIES1000D-P-4PT1T-DC is an industrial unmanaged Fast Ethernet DIN-rail PoE switch with 4 × 10/100Base-T PoE ports (IEEE 802.3af/at, PoE+, up to 30 W each) plus 1 × 10/100Base-T uplink. It delivers data and power over a single cable to IP cameras, IP phones and wireless APs, with a total PoE budget of about 120 W. Plug-and-play — no configuration — with store-and-forward switching in a compact fanless metal enclosure (32×144×95 mm) on DIN-rail (wall-mount optional). Powered by DC 48V (36–56V) with redundant dual input and reverse-polarity / overload protection, -40 to +75°C wide temperature and strong EMC immunity — ideal for compact industrial surveillance and edge PoE deployments.

ZJIES1000D-P-4PT1T-DCH	Unmanaged DIN-rail PoE Fast Ethernet switch — 4 × 10/100Base-T PoE (802.3af/at, max 30W each) + 1 × 10/100Base-T uplink, DC 48V.	✆ WhatsApp

All 5 ports are 10/100Base-T; ports 2–5 are PoE (802.3af/at, up to 30W each), port 1 is a non-PoE uplink. This is a DC 48V (36–56V) unit — the factory ordering code is ZJIES1000D-P-4PT1T-DCH (48V is required to source PoE). Copper-only, no fiber. The requested model is ZJIES1000D-P-4PT1T-DC.

4-Port PoE Switch FAQ — ZJIES1000D-P-4PT1T-DC

How many IP cameras can the ZJIES1000D-P-4PT1T-DC power?

It powers up to 4 devices on its 4 PoE ports (ports 2–5), each delivering up to 30 W under IEEE 802.3af/at, with a total budget of about 120 W — an average of 30 W per port even fully loaded. That covers 4 IP cameras, including PTZ-class units on any port.

What is the port layout and which ports carry PoE?

There are 5 x 10/100Base-T RJ45 ports in total: ports 2–5 supply PoE af/at, and 1 port serves as the data uplink to your NVR or router. PoE power rides pins 1, 2, 3 and 6 (V+/V+/V-/V-, Endspan MDI Alternative A) on the same cable as data.

What supply do I need to feed the switch?

A DC 48V source in the 36–56V range, wired to the 4-pin terminal with dual redundant input. Budget for a maximum input current of 2.6 A at 48V with PoE fully loaded. Reverse-polarity and overload protection cover wiring errors during installation.

Which devices besides cameras can it power?

Any IEEE 802.3af or 802.3at powered device: IP cameras, IP phones and wireless access points are the typical loads. Because each port negotiates up to 30 W (PoE+), higher-draw devices like outdoor APs run from the same switch as low-power cameras.

Can it operate in an outdoor CCTV cabinet?

Yes — standard temperature is -10 to +60°C and the wide-temperature version covers -40 to +75°C, with 5–95% non-condensing humidity. The fanless IP40 metal case (32 x 144 x 95 mm) mounts on DIN rail or wall, with EN61000-4 Level 3 EMS immunity, a 320,000-hour MTBF and 5-year warranty.

Do the cameras need their own power wiring?

No — data and power travel on a single Ethernet cable from each PoE port, so each camera position needs one cable run only. That removes local power supplies at every pole or wall point, cutting material and labour on small 4-camera CCTV installations.
