The Lenovo 1U RackSwitch™ G8052, a 1/10 Gb Ethernet switch, is ideal for next-generation data centers. It delivers unmatched price performance, along with benefits such as server-matched airflow, lower power consumption, low latency, and easy switch management. It has 48x 10/100/1000BASE-T RJ-45 ports and four 10 Gigabit Ethernet SFP+ ports (it also supports 1 GbE SFP transceivers), and includes hot-swap redundant power supplies and fans as standard, which minimizes your configuration requirements. Unlike most rack equipment that cools from side-to-side, the G8052 has rear-to-front or front-to-rear airflow that matches server airflow.
