8-Bay Disk Drive Cabling
The disk drive cabling process involves making the connections between each disk drive and the
mux card via the ribbon (data) cables, and between each drive and the power connectors on the
backplane via the Y cables. The mux board connectors are shown in Figure 2-9.
Figure 2-9. MA3a Mux Board Connectors
The connectors in Figure 2-8 have been labeled with acronyms that designate their segment
number and connection type (see the Internal SBC Cabling section for a description). The
information in this section details the disk drive connections. For information on the SBC
connections, refer to the SBC Cabling section of this guide.
Hard Drive Connections
1
Connect the ribbon (data) cable supplied with the MultiArray to the data connector on the
hard drive ensuring that pin 1 of the cable mates with pin 1 of the drive. These
connectors are 40-pin box connectors. See Figure 2-10.
Caution: Hard disk drives with IDE interfaces can connect to the SBC. Drives with other
interfaces, such as SCSI, can not be connected to the SBC. Refer to the drive publications for
data cabling and possible interface board installation.
