The Crystal RCS4900M is purpose built as a top-of-rack switch and delivers the buffering, latency and performance characteristics necessary to excel in that role. The Crystal RCS4900M is a two-rack-unit (2RU) top-of-server rack Ethernet switch optimized for 10/100/1000 and 10 Gigabit Ethernet access devices. It is unique in the top-of-rack space because it is semi-fixed. This flexibility provides a cost-effective and modular migration path from Gigabit Ethernet to 10 Gigabit Ethernet.
