Product Overview
The SF42P-E 4 PoE Switch is a compact and efficient networking solution designed to meet the needs of various applications, including video surveillance, in hotels, shops, supermarkets, and small to medium-sized enterprises. This 4 PoE switch features 6 10/100Base-TX Ethernet ports, with ports 1-4 supporting IEEE802.3 af/at protocols for Power over Ethernet (PoE). Each PoE port can deliver a maximum output of 25.4W, while the total PoE power output for the entire switch is 65W. The switch intelligently detects whether connected devices support PoE, supplying power only to compatible devices to prevent damage to non-PoE equipment.
Key Features
- 6 10/100Base-TX Ethernet ports, with 4 PoE-enabled ports that support IEEE802.3 af/at standards for flexible power distribution.
- Maximum output power of 25.4W per PoE port and a total switch capacity of 65W.
- Automatic detection of PoE-compatible devices, ensuring only compliant powered devices receive power.
- Supports reduced transmission rate to 10Mbps for ports 1-4 via DIP switch, allowing for extended transmission distances of up to 250m using standard twisted pair cables.
- Ports 1-6 are isolated from each other to minimize conflict and broadcast domains, which helps reduce broadcast storms and enhance network communication efficiency.
- Easy installation with support for both desktop and wall mounting.
- Plug and Play functionality for straightforward setup with no configuration required.
- Ideal for applications in video surveillance, ensuring reliable connectivity for cameras and other security devices.
