FRU Configurations
This section provides information for setting up or changing the configuration of the
system Field Replaceable Units (FRUs).
Internal Storage Configurations
Hard Disk Drive Configuration
The SCSI IDs for hard disk drives are hard-wired into the SCA Ultra2 Wide LVD SCSI
interfaces in the backplane of the two disk bays within the B1000 and C3000 workstations.
Hence, SCSI IDs do not need to be set for the hard disk drives (up to two) installed in these
workstations. From top to bottom, the pre-set SCSI IDs for hard disk drives are: 6 and 5.
Similarly, no jumpers are installed at the factory, nor is any jumper installation required
at the customer’s site, on either of the hard disk drive models that are supported with the
B1000 and C3000 workstations. Both hard disk drive models may be installed into these
workstations. See the section titled “Hard Disk Drive” on page 134 for details on installing
hard disk drives.
NOTE
There must ALWAYS be a terminator at both ends of a SCSI bus. This means
one internal terminator and one external terminator.
Table 2-1 lists the default device IDs for internal storage devices. These IDs are the default
IDs for each storage device. If an existing device already uses an ID, select an alternate ID.
Figures 2-1 and 2-2 show the two types of hard disk drives supported for the B1000/C3000
workstation.
