4-port 10/100M PSE and 1-port 10/100M Uplink Fast Ethernet PoE+ Switch
Introduction
PS-254 is 4-port 10/100M PSE and 1-port 10/00M Uplink Desktop PoE+ Fast Ethernet Switch that is designed for small network environment to strengthen its network connection. It's also specially designed for video surveillance in buses, trains, subway cars and emergency vehicles. This product is compact in size, making it ideal for every user with limited space.
IEEE 802.3af/at Power over Ethernet Plus (PoE+) Ports
PS-254 features 4-port PoE+ IEEE 802.3at supplying up to 30 watts per port. This product is 56V/DC power into low-voltage DC that runs over existing LAN cable to power up IEEE 802.3at compliant network accessories. It also features high power awareness to verify whether the network device receive power is IEEE 802.3at compliant, or only the data will be sent through LAN cable. By adding PS-254 to existing networking, installing networking products such as Access Points and IP cameras can be easily managed and set up. Wireless device deployments are easily located with available power outlets and network administrators don’t need to use heavy AC power adapters anymore.
Auto-MDI/MDI-X
Every port can automatically sense your type of cable, so there is no need for crossover cables whether you are connecting this switch to another switch or to a computer.
Auto-Negotiation
Every port can automatically sense if the connected network devices are running at 10Mbps or 100Mbps and Half/Full-Duplex mode, and adjust accordingly.
Non-Blocking
This switch receives and forwards traffic seamlessly with its non-blocking wire-speed. Every port simultaneously supports up to 200Mbps of bandwidth in full-duplex mode. This feature provides full wire speed to the connected devices and allows you to run a smooth network.
Store and Forward
By this function, this switch can maximize network performance while minimizing the propagation of bad network packets.
