Bused Resource Control Command
To send a Bused Resource Control command to the shelf manager, the payload uses the
Bused Resource Control command of the SIPL.
Table 9-21: Bused Resource Control Command
Bused Resource Status Command
If the IPMC receives a Bused Resource Control command from IPMB-0, it asserts an appro-
priate event and notifies the payload which uses the Bused Resource Status command over
the SIPL. When the IPMC receives a Bused Resource Status command, the respective bit in
the IPMC status is cleared.
The payload must issue a Bused Resource Status command before the payload communi-
cation time-out time. If the payload does not issue such a command before the payload
communication time-out time, the IPMC sends the 0xC3 completion code (Time-Out) in
the appropriate Bused Resource Control command reply.
