4-56 Upgrading Your System
Installing the Optional Hot-Swap Power
Supply
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.
To install the optional hot-swap power supply, perform the following
procedures:
1.
Observe the safety and ESD precautions listed under General Information
and Static Precautions at the beginning of this chapter.
2. Prepare your system for upgrade. See Preparing Your System for Upgrade
described earlier in this chapter.
3. At the rear of the cabinet locate the power supply bay, which has a blank
cover over the front of the bay, where the optional power supply will be
installed. See Figure 4-55.
4.
Remove the blank cover by grasping its handle (1) with your right hand,
press the latch with your index finger, pull the handle down slightly (2), and
slide the cover out of the bay (3). Save the blank cover for future use.
