Note – All empty card cage slots must contain a load board (Enterprise 6000 server) or filler panel (Enterprise 5000 or 4000 servers).
B.7 Network Interfaces
Each SBus I/O board and Graphics I/O board has onboard connectors for
Additional network interfaces can be added in the form of SBus cards. The
SBus I/O board will support up to three SBus interface cards. The Graphics
I/O board will support up to two SBus interface cards.
B.8 Disk Board
The Disk board (with two SCSI disks) is an available option for the Enterprise systems. The Enterprise 6000 system supports two Disk boards (only in slots 14 and 15); the Enterprise 5000 and 4000 systems support four Disk boards.
The ID settings of the two disks on the Disk board vary according to the card cage slot location. See Appendix C, “SCSI Devices.”
B.9 Power Supplies
There are two types of power supplies in the Enterprise 6000, 5000, and 4000 systems. The power/cooling modules (PCMs) provide DC current and cooling air to boards in the card cage.
The peripheral power supply provides current for peripheral devices (such as a tape or
B.9.1 Power/Cooling Modules (PCMs)
The DC power to the centerplane is supplied by one or more PCMs. Each PCM also provides cooling air for two board slots. If a slot contains a board, the adjacent PCM slot must contain a PCM to supply cooling air.
Current from individual PCMs is shared on the centerplane.
