TP-Link T1500-28PCT is a Smart network switch equipped with 24 10/100 Mbps Fast Ethernet ports compliant with PoE+ 802.3at/af standards, 4 Gigabit 10/100/1000 Mbps ports and 2 Gigabit SFP combo slots. The device provides high data transfer performance, advanced security features, QoS and advanced second layer traffic management. The T1500-28PCT is a cost-effective solution for small and medium-sized businesses.
PoE+ IEEE 802.3at/af
The T1500-28PCT supports 24 PoE ports with 192 W power, which are compliant with IEEE 802.3at/af standards. The equipment works with wireless access points, cameras and IP phones and other PoE-enabled devices, which eliminates unnecessary cabling or power cables.
Quality of Service
To ensure better audio, data and video transmission on your network, your device uses advanced QoS service options. Network administrators can set network traffic priorities for individual IP addresses, MAC addresses, TCP or UDP ports, and so on. This ensures that the audio and video transmission is smooth, clear, and lag-free. Support for dedicated VLANs results in a harmonious and more efficient voice transmission.
L2 layer configuration
T1500-28PCT switches are equipped with a number of second layer traffic management functions, such as 802.1Q VLAN support, port isolation, port mirroring, STP/RSTP/MSTP, port aggregation and 802.3x flow control, which increases the number of possible applications. Maintenance functions such as loop back connection detection, cable diagnostics and IGMP snooping are also available. IGMP snooping allows intelligent multicast streaming to specific subscribers only, and IGMP throttling/filtering effectively limits access to multicast for unauthorized users.
The T1500-28PCT switch is easy to use and manage. It provides users with extensive management capabilities, offering an intuitive graphical user interface (GUI) operated via a web browser. With SNMP (v1/2/3) and RMON support, the device can send out unforeseen event messages and monitor device status.

PoE switch works simultaneously as a PSE switch and an access layer switch, when choosing the switch we can take into account the following aspects:
The physical port
The PoE switch is connected to PoE PDs as an access layer switch, you should consider the number of PDs to determine the number of PoE switch interfaces. The baud rate of the end devices should also be considered depending on the data type, e.g. 11AC EAP should connect to the Gigabit PoE switch.
Power standard PoE
Depending on the PD devices (such as AP or IP camera) supported by PoE (such as 802.3af or 802.3at or passive PoE), the PoE switches must be compatible with the appropriate PoE power supply standard. More about TP-Link switches and their standards you will find there
