The E-Link EL-104PS 04-Port PoE 2-Uplink Networking Switch with VLAN is a type of Power over Ethernet (PoE) switch that provides both data and power to connected devices over Ethernet cables. Let's break down the main features of this model:

Key Features:

1. 4 Ports:

   • It has 4 ports for network connections, which are likely PoE-enabled. This means that devices like IP cameras, VoIP phones, or wireless access points can receive both data and power through a single Ethernet cable.

   PoE (Power over Ethernet):

   • The PoE functionality allows the switch to deliver power to compatible devices. The switch usually provides IEEE 802.3af (PoE) or IEEE 802.3at (PoE+) standards, depending on the specific model. This eliminates the need for separate power cables for devices.

   2 Uplink Ports:

   • The switch includes 2 uplink ports (likely Gigabit or Fast Ethernet) that allow you to connect to other networking equipment like routers, additional switches, or even a network backbone.

   VLAN Support:

   • The VLAN (Virtual Local Area Network) support allows you to segment network traffic into different virtual networks within the same physical switch. This can help improve security, network performance, and management by isolating traffic based on department, function, or device type.

   Networking Applications:

   • This switch is well-suited for small-to-medium office environments or surveillance systems where you need to connect multiple PoE devices and manage network traffic through VLANs.

Technical Specifications (Typical):

• Port Types: 16 x Gigabit Ethernet PoE Ports (10/100/1000), 2. x Gigabit ,2 x SFP Uplink Ports.

• PoE Power Budget: The total power budget typically depends on the power supply in the switch, and it can provide a certain number of watts across all PoE+ ports (usually 240W+).

• VLAN Support: Yes, typically supporting IEEE 802.1Q.

• Switching Capacity:  52Gbps.

Possible Use Cases:

• Security Camera Systems: Connect PoE-powered cameras and manage them in separate VLANs for better network management.

• VoIP Phones: Power IP phones while managing their network traffic via VLANs.

• Wireless Access Points (WAPs): For extending network coverage in offices or larger homes.

• Small to Medium Networks: Provide connectivity and power to devices like wireless access points, routers, and other networked hardware.

Considerations:

PoE Power Budget: The total power budget of the switch should match the number of devices that need power. If the switch provides 30W per port, and you have 6 devices, ensure the switch can handle the total power demand.
Heat Dissipation: Since PoE switches deliver both power and data, they can generate heat. Make sure the switch has proper ventilation or is placed in a cool, well-ventilated area.
Range of Compatibility: Always verify that your devices are PoE-compatible, or check if you need injectors for devices that are not PoE-enabled.

E-Link EL-104PS  6-Port 10/100M PoE+ 2 Uplink Switch

E-Link EL-104PS is a 6-port 10/100Mbps switch with 4 PoE port and 2 Uplink port. Electrical power and data transfer on the same cable can allow you to expand your network to areas where there are no power lines or outlets, allowing you to install devices such as APS, IP cameras, IP phones,IP Access Point  and so on. The CCTV capability on the EL104PS helps enhance the network environment and lower network maintenance expenses. It is simple to operate and maintain, and it may be used in a variety of networking situations, including business buildings, communities, hotels, and workplaces. It is extremely simple to use because of its basic plug-and-play interface. It is composed of high-quality metal and has a durable design. This extends the service life and improves heat dissipation, making it ideal for most settings. It also has a fanless design for whisper-quiet operation. The Elink EL104PS 6-Port 10/100M PoE+ Switch comes with a 2-year warranty.
