Connecting cables
Connecting cables includes:
• Cabling best practices
• Connecting SCSI cables
• Connecting Ethernet cables
• Connecting power cords
Cabling best practices
• Use the shortest possible cable between devices. Shorter cables are easier to manage and
route along the back of the rack. In addition, shorter cables reduce the possibility of signal
degradation that can occur over longer distances.
• Ensure that the cabling in the back of the rack system does not interfere with system operation or
maintenance. Bind the cables loosely with cable ties and route the excess cables out of the way,
along the side of the rack. When the cables are tied together and routed down the side of the
rack, system components and indicators are easily visible and accessible.
• Attach a label near both ends of each cable to identify the device connected to that cable.
Include the device, device name, port, or other useful information.
• Use colored markers to color-code both ends of each cable, to help you visually identify a
particular cable without having to read or locate the label.
Connecting SCSI cables
To connect the MSA1510i to the storage enclosures, use standard VHDCI SCSI cables.
IMPORTANT:
Be sure that the SCSI I/O module(s) are securely seated in the MSA1510i chassis and that the
thumbscrews on the SCSI cables are tightened, to ensure a secure connection.

SCSI port, bus, and preassigned box numbers
HP recommends installing additional SCSI I/O modules and connecting storage enclosures in the same
sequence as the preassigned box numbers, as illustrated in the following image:
