Test Name Description Special Considerations
su@14,3083f8
Tests mouse control and input
logic, including internal and
external loopback tests. Mouse tests are not run if a
keyboard is used as an input
device.
To run external loopback tests,
you must have a special passive
loopback connector attached to the
keyboard/mouse port, the variable
diag-targets
must be set to
loopback
,
device&loopback
, or
device&loopback,3
.
The Sun part number for the
loopback connector is 501-4690-01.
rsc
Tests RSC (SSP) hardware,
including RSC serial and Ethernet
ports. For additional details, see
“About Remote System Control
(RSC)” on page 256. This test is not run if RSC is being
used as the console device.
To run external loopback tests on
the RSC Ethernet port, the port
must be connected to a 10-Mbps
Ethernet network. The variable
diag-targets
must also be set to
loopback3
or
device&loopback,3
.
To run external loopback tests on
the RSC serial port, a special
passive serial loopback connector
must be attached to the port. The
variable
diag-targets
must also
be set to
loopback
,
device&loopback
, or
device&loopback,3
.
The Sun part number for the
passive serial loopback connector is
501-4205-01.
1. Depending on your system configuration, the OBDiag menu may include tests for additional SCSI interfaces,
such as
scsi@4
,
scsi@4,1
,
