Servicing SPs
The servers have two redundant SPs: SP0 and SP1.
In SPARC M8-8 and SPARC M7-8 servers, the SPs are located in the CMIOU chassis. See SPARC M8-8 and SPARC M7-8 Configurations and Failover Behavior (Two PDomains) and SPARC M8-8 and SPARC M7-8 Configurations and Failover Behavior (One PDomain) for information about SP configurations on these servers.
In a SPARC M7-16 server, the redundant SPs (SP0 and SP1) are located in the switch chassis. These SPs manage system activity. The SPARC M7-16 also contains two SPPs in each CMIOU chassis that manage DCU activity. The top CMIOU chassis contains SPP2 and SPP3, and the bottom CMIOU chassis contains SPP0 and SPP1. For information about SP and SPP configurations on this server, see SPARC M7-16 Configurations and Failover Behavior.
For the location of the SPs and SPPs, see CMIOU Chassis Rear Components and Switch Chassis Rear Components (SPARC M7-16).
Note - Replace a failed SP or SPP as soon as possible. Do not remove an SP or SPP until a replacement is available.
 | 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. |
 | Caution - The SPARC M8-8 servers include SPs that are not compatible with the SPARC M7 servers. Never install a SPARC M8 SP in a SPARC M7 server, and never install a SPARC M7 SP in the SPARC M8-8 server. The SPARC M8 SP has a SPARC M8 label on its left extraction lever (see SER MGT and NET MGT Port Locations and Numbering). The SPARC M7 SPs do not have a label. |
These topics explain how to service the SPs and SPPs.
