Replace a Fan
If a fan fails, the remaining fans ramp up to full speed, the Error LED on the control panel
lights, and an email alert is sent to the system administrator. Replace a failed fan as soon as
possible. Remove the top chassis cover while the system is still running to determine which
fan failed.
Fans are hot-pluggable, so you do not need to power down your system when replacing a
fan.
To replace a fan on a 2120:
1. Remove the chassis cover.
For more information, see Access the Inside of the Storage System on page 40.
2. Disconnect the fan’s power connections.
