Deployment
The switch is designed for high-availability environments with a high port density. The switch includes
redundant, hot-swappable, load-sharing AC PSUs, a hot-swappable fan tray, and port-to-power and
power-to-port airflow direction options. Meeting the network scaling requirements of enterprise and cloud data
centers, the switch can be deployed as a top-of-rack switch providing full line-rate switching at Layer 2 or
Layer 3 across all ports.
Rack Cooling
The top-of-rack switch is a high-performance, high-density unit that generates a substantial amount of heat.
When mounted in a rack with other equipment, it is important that the switch has the same airflow direction to
avoid
hot loops in the data center aisles. Hot loops increase cooling requirements since warm air is drawn into
rack devices instead of cool air.
Most rack-mounted blade servers draw cool air from the front and expel hot air at the rear. The top-of-rack
switch includes power supply units and a fan tray module that have a front-to-back (F2B) airflow direction that
maintains cool aisles in the data center.
