Power Supply Modules

About the Power Supply Modules

The Topspin 270/Cisco SFS 7008 power supply units are hot-swappable. Only one power module is
necessary to power the unit. However, two power supplies are recommended for redundancy.
You can add a second module without powering off the chassis. If you have two power supply units
installed, you can remove one of them without removing power from the chassis.
