Redundant Hot-Swap Power Supplies
Redundant Hot-Swap Power Supplies  
Ensure maximum availability with an n + 1 redundant power supply. n + 1 means each of our redundant power supplies has one hot spare power module for maximum reliability – your system stays on even if one power module fails. Modules can be "hot-swapped" (replaced while the power supply is running), so there is no need to power down to replace a module – your application continues uninterrupted. If a power module fails, the power supply will sound an alarm.

Note: a 400W dual redundant power supply, for example, includes two 400W power modules. Be sure to order a spare power module.
