SPARC M8-8 and SPARC M7-8 servers each have a single CMIOU chassis. For the location of the chassis, see Server Front Components (SPARC M8-8 and SPARC M7-8 Servers).
SPARC M7-16 servers have two CMIOU chassis and a single switch chassis. For the locations of these chassis, see Server Front Components (SPARC M7-16).
The steps involved in replacing either of these chassis are the same.
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.
These topics explain how to service the CMIOU chassis.
