packets (10BaseT—Twisted Pair
Ethernet) on the Ethernet
cable(s) connected to the
system. Connect the system to the
network via the desired
Ethernet port. See description.
watch-net-all

Ethernet port. When an SBus card
network controller card
is installed.
probe-scsi
Returns the SCSI devices
(internal and external) and their
SCSI targets connected to the
built-in SCSI port. Connect external SCSI
devices to the system and
turn on their power. (These tests do not
apply to the SPARC
Xterminal 1 system.) To
determine if a SCSI
peripheral is talking to
the system.
To determine the SCSI
targets (addresses) of a
SCSI device.
To determine if more
than one SCSI
peripheral is assigned
the same SCSI address.
To determine if the
built-in SCSI controller
is defective.
probe-scsi-all
Returns to the display the SCSI
devices and their SCSI targets
connected to all SCSI ports
(both the built-in SCSI port and
any additional SCSI host
adapter cards). Connect external SCSI
devices to the system and
turn on their power. See

To determine if a SCSI
host adapter controller
is defective.
