rsc
1. Depending on your system configuration, the OBDiag menu may include tests for additional SCSI interfaces, such as scsi@4,
scsi@4,1, scsi@5, scsi@5,1, etc.
Description
Tests keyboard control and input
logic, including internal and
external loopback tests.
Tests mouse control and input
logic, including internal and
external loopback tests.
Tests RSC (SSP) hardware,
including RSC serial and Ethernet
ports. For additional details, see
"About Remote System Control
(RSC)" on page 241.
Special Considerations
Keyboard tests run only when a keyboard is
used as the 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.
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.
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.
