Hot-Swap Power Supply

Your server may contain a modular hot-swap power supply like the one shown in Figure 4-26. The addition of a second hot-swap power supply makes your system so that it has redundant power and can be operated continuously without interruption if either of the power supplies malfunction.

Installation

1.Prepare your system for upgrade. See Preparing Your System for Disassembly and Reassembly describes earlier in this chapter.

2.Loosen a screw securing the blank cover to remove the cover from the chassis. Remove the cover and save it for future use. See Figure 4-26.
