Power Supply Modules
About the Power Supply Modules
The Topspin 270 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.
About a Failed Power Supply
If you believe a power supply module has failed, contact technical support.
Do not remove a failed power supply unless you have a new power supply to install immediately, or a
blanking panel to place over the open bay as overheating may occur.
