A CMIOU chassis contains six power supplies. For the location of these power supplies, see CMIOU Chassis Front Components.
A switch chassis contains four power supplies (SPARC M7-16). For the location of these power supplies, see Switch Chassis Front Components (SPARC M7-16).
The power supplies are 2N redundant. In the event that a power supply fails in either chassis, the system can operate with only three power supplies in the switch chassis or five power supplies in the CMIOU chassis.
There are no restrictions into which slots the power supplies have to be installed. You can install them in any of the power supply slots.
Caution - The SPARC M8-8 server includes power supplies that are not compatible with the SPARC M7 servers. Never install a SPARC M8 power supply in a SPARC M7 server, and never install a SPARC M7 power supply in the SPARC M8-8 server. The SPARC M8 power supplies include three shims installed on one side of the power supply (see Remove the Power Supply Shims (SPARC M8)). |
These topics explain how to service the power supplies in the server.
