SBus expansion

subsystem (SES)board

A peripheral device attached to a SPARCsystem or SPARCserver. The SBus expansion board subsystem provides four additional SBus slots. The SBus expansion board system consists of the following: the SBus expansion board, the expansion adapter card (in the SPARCsystem, and the expansion system cable.

SES

SBus Expansion Subsystem

SES adapter card

A single-width SBus card which must be inserted into the SPARCsystem or SPARCserver in order to operate the SBus expansion system. This card transmits SBus related information to external hardware.

SES cable

A shielded round cable which connects the SBus expansion adapter card, installed in the SPARCsystem or SPARCserver, and the 96-pin connector on the back panel of the SBus expansion board. The cable has 96-pin female connectors on each end.
