Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 59.
Your server supports up to eight hot-swap system fans. This design helps you to avoid significant cooling
problems when a system fan fails and you can replace a hot-swap system fan without turning off the server.
CAUTION:
Hazardous moving parts. Keep fingers and other body parts away.
