Connecting the Interface Cables
This chapter explains how to connect:
• SCSI cables
• Fibre Channel cables
• Ethernet cables
Note: If the interface cables are going under a raised floor, the floor tile under

Connecting the SCSI Interface

The customer may choose to separate the control path and the data paths. The
control path transfers client commands for library robotic operations. The data
path transfers data to and from the drives.
Note: If you are connecting the library or drives to an LVD SCSI bus, the cable

SCSI Terminators

A terminator is a device that attaches to the end-points of the SCSI bus or daisy
chain. The terminator absorbs signals so that they do not reflect back down the
bus and they keep the power levels of the bus consistent. A single terminator is
required at the end of the bus. StorageTek has the following terminators:
• PN 10148002 (single-ended)
• PN 10148003 (HVD)
• PN 10048031 (LVD and single-ended)

HVD General Requirements

The library SCSI control and data path cables must be 68-pin high density (HD)
connectors at the library. While single-ended cables may be used, their
connectors must be adapted to a 68-pin differential connector for the library
connection.
Because system cables vary, you may need an adapter to connect to the library.
