1 # Multiple Chassis
5 A BMC-based system can contain one or more chassis. A chassis is typically a
9 A chassis can be stand-alone, such as a tower or desktop. A chassis can also be
12 For the `phosphor-power-sequencer` application, the term "single chassis system"
13 means the system type has a maximum configuration of one chassis. If the system
14 type has a maximum configuration of multiple chassis, then it is considered a
15 "multiple chassis system" even if the current system only contains one chassis.
17 ## Differences between single and multiple chassis systems
19 ### System and chassis power state
21 In a single chassis system, the system and chassis power state are identical.
24 In a multiple chassis system, each chassis has its own power state. Even if the
25 system is on, an individual chassis may be off. This can occur if that chassis
28 See [Chassis Status](chassis_status.md) for more information.
30 ### Chassis power good faults
32 If a single chassis system experiences a power good (pgood) fault, the system is
35 If a multiple chassis system experiences a power good (pgood) fault in one
36 chassis, the system will be powered off and then powered on again without that
37 chassis.
43 If a single chassis system that was powered on experiences a brownout, the
46 If a multiple chassis system that was powered on experiences a brownout in one
47 chassis, the system will be powered off and then powered on again without that
48 chassis.
54 If a single chassis system that was powered on experiences a blackout, the
59 If a multiple chassis system that was powered on experiences a blackout in one
60 chassis, that chassis loses all power. The system will be powered off and then
61 powered on again without that chassis.
