FAQ

Can I mix red and blue power supplies or fans in one switch?
No. Every fan and power supply in a switch must have the same airflow direction as the switch.

Why choose a 7280R over a 7050X?
The 7280R uses deep packet buffers (gigabytes rather than megabytes), so it absorbs traffic bursts at the spine, data center edge and interconnect where shallow-buffer switches drop packets.

What's Included

Power supplies and fans ship with a switch when its title names an airflow direction (F-B or B-F); the listing's What's Included section names the exact parts. Otherwise they are sold separately so you can choose AC or DC input and the airflow. Optics are always sold separately.
