48 Gigabit Ethernet ports and 4 10-Gigabit SFP+ slots
Supports auto-learning and auto-aging for up to 32K MAC addresses
10K jumbo frames to increase data transfer rates
IEEE-802.3x flow control protects against packet loss and ensures reliable data transfer
Minimizes power consumption through modern energy efficiency (IEEE-802.3az)

Gigabit speeds: Bring your data up to date with the latest technology.
The GTU-5211 from LevelOne is a 52-port Gigabit Ethernet switch that offers you a
powerful, cost-effective, easy-to-use and seamless upgrade
to bring your network into the Gigabit age. Increase the speed of your network backbone to a massive 176 Gbps and bring gigabit speeds to your computers.

Bandwidth hungry? No problem.
What happens when multiple users access multimedia applications at the same time? No need to worry, because with the GTU-5211 you can move large files faster and easier. Simply connect your NAS via an SFP+ port with a DAC cable and transfer your CGI, CAD, video or other large multimedia files over the network instantly and without delay.

Plug and Play, flexible and simple
The GTU-5211 is plug and play, so no configuration is required. The
automatic MDI/MDI-X cable detection on all ports eliminates the need for crossover cables or uplink ports. Each port can be used as a general purpose port or uplink port, and each port can be easily connected to a server, hub, router or switch using a standard patch cable or crossover cable. Diagnostic LEDs that indicate link status and link activity allow you to quickly identify and troubleshoot network issues.
