Chapter 6 Installing and Upgrading Internal Modules and FRUs

Replacing Power Supplies and Redundant Power Supplies

Warning Care should be taken while removing the power supplies and power inverters (especially in boost mode of operation). If the total power consumption is higher than can be supported by one power supply alone and in this condition a power supply is removed, the hardware can be damaged. This may then result in the system being unstable or unusable.

All of the power supply and RPS options have a similar modular form factor, with no cabling, for easy removal and replacement. If an RPS is attached, the power supply may be hot-swapped.
