A regular switch is connected after the PoE switch

A regular switch can safely be connected downstream of a PoE switch, but it will only handle data, not power.Key ConsiderationsData Transmission: When a regular switch is connected to a PoE switch, it will function normally for data transfer. All devices connected to the regular switch will communicate over the network without issues, as the PoE switch still handles the upstream data routing . Power Delivery: A regular switch does not provide Power over Ethernet (PoE). Devices connected to it will not receive power through the Ethernet cable. If you need to power devices like IP cameras, VoIP phones, or wireless access points, you must either connect them directly to the PoE switch or use a PoE injector between the regular switch and the powered device . Safety: Connecting a PoE-enabled cable to a regular switch is generally safe. The regular switch will ignore the PoE voltage and only use the cable for data transmission. There is no risk of damaging the switch as long as the devices are standard Ethernet-compliant . Network Setup: Ensure that each device has a unique IP address and that the network topology avoids loops. The regular switch will act as an extension of the PoE switch, expanding the number of available ports for data-only devices . Best Practices:Use high-quality Ethernet cables rated for the network speed and PoE if needed.If powered devices must be connected downstream, consider using a midspan PoE injector to supply power.Monitor network performance to ensure that adding the regular switch does not create bottlenecks or overload the PoE switch's bandwidth . In summary, connecting a regular switch after a PoE switch is a common and safe practice for expanding a network. The regular switch will handle data traffic effectively, but any devices requiring PoE must either remain on the PoE switch or receive power via an injector. Proper cabling and network configuration ensure smooth operation and device safety.
