Product Overview

TBC-4PS4505N is a 5-port Gigabit PoE switch featuring 4 × 10/100Mbps adaptive PoE ports and 1 × 10/100/1000Mbps Gigabit RJ45 uplink port. It supports IEEE 802.3af/at PoE standards, with a maximum PoE output of 30W per port and a total PoE power budget of 65W.The switch supports Standard Mode and Extended Mode. In Standard Mode, the maximum PoE transmission distance is up to 100 meters. In Extended Mode, the transmission distance of PoE ports can reach up to 250 meters.Featuring a durable steel-alloy housing and built-in power supply, the switch offers reliable operation and is suitable for connecting and powering PoE-powered devices such as IP cameras, wireless access points, and IP phones.

Key Features

• Compliant with IEEE 802.3 10BASE-T, IEEE 802.3u 100BASE-TX, IEEE 802.3ab 1000BASE-T, IEEE 802.3af, and IEEE 802.3at standards.

• Supports both half-duplex and full-duplex operation. IEEE 802.3x Flow Control is supported in full-duplex mode, while Back Pressure Flow Control is supported in half-duplex mode.

• Equipped with 4 × 10/100Mbps adaptive PoE ports and 1 × 10/100/1000Mbps adaptive RJ45 uplink port. All four PoE ports comply with IEEE 802.3af/at standards and support a maximum PoE output of 30W per port. All RJ45 ports support Auto MDI/MDIX for flexible connection to IP cameras, wireless APs, upstream switches, routers, and other network devices.

• Ethernet ports support 4KV surge protection, improving device stability and reliability.

• Adopts Store-and-Forward switching architecture with wire-speed forwarding capability.

• Features a high-performance switching chipset combined with a metal housing and natural heat dissipation design for stable and reliable operation.

• Supports 100m/250m transmission mode switching and VLAN Isolation. In 100m mode, the switch operates in standard transmission mode. When switched to 250m Extended Mode, ports 1–4 can transmit data and PoE power up to 250 meters at 10Mbps, and VLAN Isolation is automatically enabled. When port isolation is enabled, PoE ports are isolated from each other and can communicate only with the uplink port, effectively reducing broadcast storms and improving network security and transmission stability. The switch must be restarted after changing the mode for the new setting to take effect.
