To remove a hot-swap power supply, complete the following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 21.
Attention: Static electricity that is released to internal server components
when the server is powered-on might cause the server to halt, which could
result in the loss of data. To avoid this potential problem, always use an
electrostatic-discharge wrist strap or other grounding system when working
inside the server with the power on.
2. Remove the server cover. See "Removing the cover and bezel" on page 23.
