"PoE switch and a non-PoE switch" or perhaps different types of PoE switches

Difference Between a PoE Switch and a Non-PoE Switch：

PoE Switch

- Power over Ethernet (PoE): PoE switches can deliver power over Ethernet cables to connected devices, such as IP cameras, VoIP phones, and wireless access points. This eliminates the need for separate power supplies for each device.

- Convenience: They simplify installations by reducing the number of cables required and make it easier to deploy devices in locations without easy access to power outlets.

- Standards: PoE switches adhere to various IEEE standards such as 802.3af (PoE), 802.3at (PoE+), and 802.3bt (PoE++), which dictate the amount of power they can supply. For example, 802.3af provides up to 15.4 watts per port, while 802.3at provides up to 30 watts per port.

Non-PoE Switch

- No Power Delivery: Non-PoE switches can only transmit data, not power. Devices connected to these switches must have their own power supplies.

- Use Cases: They are suitable for environments where all connected devices have their own power sources or do not require power over the network cable.

- Cost: Typically, non-PoE switches are less expensive than PoE switches due to the absence of power delivery capabilities.

Different Types of PoE Switches：

PoE vs. PoE+ vs. PoE++

- PoE (802.3af): Provides up to 15.4 watts of power per port. Suitable for low-power devices like IP phones and some wireless access points.

- PoE+ (802.3at): Provides up to 30 watts of power per port. This is ideal for devices that require more power, such as PTZ (pan-tilt-zoom) cameras and more robust wireless access points.

- PoE++ (802.3bt): Provides up to 60 watts (Type 3) or 100 watts (Type 4) per port. This is used for very high-power devices, including some high-end lighting systems and more powerful networking equipment.

Managed vs. Unmanaged PoE Switches

- Managed PoE Switches: These offer advanced features like VLAN support, QoS (Quality of Service), SNMP (Simple Network Management Protocol), and the ability to control power output on individual ports. They are suitable for complex network environments where detailed control and monitoring are necessary.

- Unmanaged PoE Switches: These provide basic connectivity without advanced features. They are typically plug-and-play and are suitable for simpler networks where advanced configuration and monitoring are not needed.

- PoE Switch: Can deliver power and data over Ethernet cables, simplifying installations for devices that require power.

- Non-PoE Switch: Only delivers data, requiring connected devices to have their own power sources.

- Types of PoE: Vary based on power delivery capacity (PoE, PoE+, PoE++).

- Managed vs. Unmanaged: Managed switches offer advanced control and monitoring, while unmanaged switches are simpler and easier to set up.

Choosing between these options depends on your specific network requirements, the devices you plan to connect, and your budget constraints.
