Beep Sequences During System Boot
During system POST, the audible alarm on the controller will produce one of a number of
beep sequences to indicate the status of the controller. See
Table 2-3
for a description of
these beep sequences.
2.3
SCSI Termination
Termination is a commonly overlooked requirement when connecting SCSI devices
together. When these devices are connected together, the resulting set of devices is
typically referred to as a SCSI bus. SCSI devices such as hard disks and tape drives must
be terminated if they are the last physical devices at either end of the SCSI bus (if nothing
else is actively terminating the end of the bus such as a terminator or backplane). If a
device is inserted into the middle of the SCSI bus, then it (the device itself) should not be
terminated. Only terminate each end of the bus. See
Table 2-1
for a list of jumper block
(J1) SCSI bus termination settings.
