Installing or replacing a hot-swap redundant power supply
Attention: Do not open your server or attempt any repair before reading and understanding the “Safety information”
on page iii and “Guidelines” on page 83.
This topic provides instructions on how to install or replace a hot-swap redundant power supply. This topic
applies only to server models that come with one or two hot-swap redundant power supplies.
The hot-swap redundant power supply adds a second source of power to the server. When the server is
populated with two hot-swap redundant power supplies, it can withstand a power loss from either power
supply. This helps you avoid significant interruption to the operation of the server when a power supply fails.
You can replace the failing hot-swap redundant power supply without turning off the server.
