Appendix B
Installing the library on the SCSI bus
This section provides the basic rules and considerations for setting
up the library on the SCSI bus.
Single-ended, HVD, or LVD
The Exabyte X200 supports an LVD (low-voltage differential) or
HVD (high-voltage differential) SCSI configuration. If you have
an LVD library, every SCSI device attached to the SCSI buses
connecting to or from the library must be LVD. If you have an
HVD library, every SCSI device must be HVD. These SCSI devices
can include the tape drives installed in the library, the adapter
card installed in the host computer, additional devices attached
to the SCSI bus, and terminators.
Although LVD SCSI is compatible with single-ended SCSI, the
internal SCSI cable lengths for the X200 LVD library may cause
the total cable length to exceed the maximum length allowed for
a single-ended bus (see
support single-ended devices on the library's LVD SCSI bus.

Do not connect the LVD library to a single-ended
bus. Doing so may cause the bus to hang.
Also, do not mix LVD and HVD devices on the same
SCSI bus, or you may damage the devices attached
to that bus.
