Quick Guide

This guide covers the setup and operation of the UGREEN 10-Port Gigabit PoE Switch (CM742-35372). Key operational requirements include using only the original power adapter, ensuring proper ventilation, and connecting non-PoE devices exclusively to the uplink ports to prevent hardware damage. The device supports a total PoE power budget of 60W.

Safety Information

Non-PoE Devices: Do not connect computers, set-top boxes, or non-PoE cameras to PoE ports. Use only uplink ports for these devices.
Environment: Keep ventilation openings unobstructed. Avoid high-temperature, poorly ventilated, wet, or flammable areas.
Cabling: Keep network cables away from high-voltage lines and strong magnetic interference.
Power: Use only the original power adapter. Do not touch exposed metal contacts while powered.

Product Overview

Port Configuration: 8 x Gigabit IEEE 802.3af/at PoE ports (up to 30W per port, 60W total budget) + 2 x Gigabit non-PoE uplink ports.
Speed: 10/100/1000 Mbps auto-negotiation.
Protection: 6KV surge protection, short-circuit, over-load, and over-temperature protection.
Transmission Distance: Up to 100m in normal mode; up to 250m in extended mode.

Installation and Connection

The switch can be placed on a desktop or wall-mounted. Ensure the installation is secure to prevent falling.

Preparation: Check package contents (switch, power adapter, mounting screws, manual). Use Cat5e or above Ethernet cables.
Uplink Connection: Connect your router or modem LAN to the switch's uplink ports.
PoE Devices: Connect PoE cameras, access points, or other PoE-powered devices to the 8 PoE ports.
Non-PoE Devices: Connect computers, printers, and other non-PoE devices only to the uplink ports.
Power Supply: Connect the original adapter to the power port and mains supply. The device powers on automatically.

DIP Switch Modes

Standard Switch Mode: All ports communicate with each other for general networking.
VLAN Isolation Mode: PoE ports are isolated from each other; they only communicate with uplink ports.
Extend Mode: Extends PoE transmission distance to 250m (at 100Mbps speed) for long-distance monitoring.

LED Indicators

PWR: On = power normal; Off = power failure.
Port LEDs: On = link connected; Blinking = data transmitting; Off = no link.
PoE Indicator: On = PoE normal; Blinking = abnormal/overload; Off = no PoE device.

Troubleshooting

If you encounter issues, consider the following:

PoE device not powering on: Ensure the device is IEEE 802.3af/at standard, check if the Ethernet cable is 8-core and intact, reduce the number of PoE devices to avoid overload, or test with another PoE port.
No network connection: Verify uplink connection to router/modem, enable DHCP, switch to Standard Mode if VLAN Isolation is enabled, or restart the switch.
Monitoring lag: Switch to Extend Mode for long-distance wiring, use Cat5e/Cat6 cables, or reduce concurrent high-definition video streams.
Frequent disconnection: Ensure you are not exceeding the 60W PoE budget and check for short circuits in cables.

Practical help

Common problems

PoE device will not power on

Verify the device is IEEE 802.3af/at compliant, check that the Ethernet cable is 8-core and intact, and ensure the total PoE power budget (60W) is not exceeded.

No network connection

Verify the uplink connection to the router/modem, ensure DHCP is enabled, and check if VLAN Isolation mode is active (switch to Standard Mode if necessary).

Monitoring lag or slow transmission

Switch to Extend Mode for long-distance wiring, use Cat5e or Cat6 cables, and reduce the number of concurrent high-definition video streams.

Frequent disconnection or unstable power

Ensure the total 60W PoE power budget is not exceeded, use the original power adapter, and check for short circuits in the cables.

Before use

Verify package contents: switch, power adapter, mounting screws, manual.
Ensure the installation area is dry, ventilated, and free from heat or electromagnetic interference.
Use Cat5e or higher grade Ethernet cables.
Confirm that PoE devices are IEEE 802.3af/at compliant.
Ensure the total power consumption of connected PoE devices does not exceed 60W.

Specs in practice

Uplink Ports: 2 Gigabit ports intended for non-PoE devices like routers, modems, or computers.
VLAN Isolation: Prevents PoE ports from communicating with each other, allowing them to only talk to uplink ports.

Model compatibility

Non-PoE devices must NOT be connected to PoE ports; use only uplink ports.
PoE devices must be IEEE 802.3af/at standard compliant.
Use Cat5e or above Ethernet cables for optimal performance.
