PCI Riser Card Locations
The PCI card has two integrated SCSI controllers. One SCSI controller (PCI, 64-bit) is an SYM53C1010
that operates at 66MHz and has dual LVD (low voltage differential) ports. The other is a 53C875, SE-SCSI
controller and is only available on the six-slotted PCI riser card. The internal port from SCSI controller
SYM53C1010 connects to the DASD board through a 68-pin SCSI cable. The port from the SE-SCSI
controller is available only on the six-slotted PCI riser card, and connects to the media bay through a
68-pin SCSI cable.
All PCI-X slots can run either 64-bit or 32-bit adapters. However, a 32-bit adapter operates in a 32-bit
mode and shows no performance advantage while running in a 64-bit slot.
The following illustrations show the PCI adapter slot locations when viewing from the rear of the system.
