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 Core IO Board
The SEU core IO card is the same one used in the server chassis. Up to two core IO cards can be
plugged into the SEU. Two core IO cards enable two additional IO partitions to be added to the
number of partitions that exist in the server attached to the SEU. Since the server can have up to
two partitions, the total number of partitions possible in a server with the SEU attached is four
partitions.
The core IO card can be replaced with standby power applied. The system power to the core IO
is handled in the hardware the same way a hot-plug PCI/PCI-X card is handled. Standby power
to the core IO is handled by power manager devices to limit inrush current during insertion.
Mass Storage (Disk) Backplane
Internal mass storage connections to disks are routed on the mass storage backplane, having
connectors and termination logic. All hard disks are hot-plug while removable media drives are
not hot-plug. The SEU accommodates two internal, removable media devices. Therefore, power
connectors for a removable media drive are required on the mass storage backplane.
