Lenovo RackSwitch G8052
Product Guide
The Lenovo RackSwitch™ G8052 (as shown in the following figure) is a top-of-rack data center switch that
delivers unmatched line-rate Layer 2/3 performance at an attractive price. 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.

    1.8 microseconds. Lower power and better cooling The RackSwitch G8052 typically uses only 130 W of power, a fraction of the power consumption of most competitive offerings. The G8052’s rear-to-front or front-to-rear cooling design reduces data center air conditioning costs by matching airflow to the server’s configuration in the rack.
