1. Each slot will auto select the proper speed for the card installed up to the maximum speed for the slot. Placing
high speed cards into slow speed slots will cause the card to be driven at the slow speed.
2. Slot is driven by a single rope and has a maximum speed of 66 MHz.
MP/SCSI Board
Up to two MP/SCSI cards can be plugged into the server. At least one MP/SCSI board is required
(independent of partitions). An additional MP/SCSI board is required in a dual partition system.
Both MP/SCSI boards are oriented vertically and plug into the system backplane. The MP/SCSI
board incorporates a dual channel Ultra320 SCSI controller and is hot-pluggable.
LAN/SCSI Board
At least one LAN/SCSI board is required for the minimum system configuration. Two are required
in a dual partition system. The LAN/SCSI board is a standard PCI form factor card with PCI card
edge connectors. The PCI-X backplane has one slot location reserved for the required board and
another that can accommodate either a second LAN/SCSI board or any other supported add-in
PCI-X card. The LAN/SCSI board is hot-pluggable.
Mass Storage (Disk) Backplane
Internal mass storage connections to disks are routed on the mass storage backplane, which has
connectors and termination logic. All hard disks are hot-plug, but removable media disks are
not. The servers accommodate one internal, half-height, removable media device, or two internal,
slim line DVD+RW removable media devices.. The mass storage backplane incorporates a circuit
that enables power to the internal removable media device to be programmatically cycled.
