Servicing CMIOUs
A CMIOU chassis contains up to eight CMIOUs. For the location of the CMIOUs, see
“CMIOU Chassis Rear Components” on page 21.
Caution - This procedure requires that you handle components that are sensitive to electrostatic
discharge. This discharge can cause server components to fail. Follow antistatic precautions to
prevent electrostatic damage. See “Prevent ESD Damage” on page 61.
These topics explain how to service CMIOUs.
