The external SCSI cable configuration allows the unused SCSI port on the system board to be routed externally through a PCI slot. This option is only available if the server is operating in simplex mode.
CAUTION: Always route the optional external simplex SCSI cable to avoid interference with the fan assembly or PCI riser cage installation.
CAUTION: To maintain proper airflow and to prevent thermal damage, do not block the fans with server cabling.
