SUNW,envctrltwo

@14,60000

Verifies that the fans are operational. Checks that the temperature in the enclosure and at the CPUs does not exceed the maximum allowable range. Also tests the disk and front panel LEDs. 

ebus@1

Tests the on-board ASIC that interfaces the following devices with the PCI bus: parallel port, serial port, keyboard, mouse, diskette drive, NVRAM, and the environmental monitoring and control system. 

ecpp

@14,3043bc

Tests parallel port I/O logic, including internal and external loopback tests. 

To run external loopback tests, you must have a special passive loopback connector attached to the parallel port. The variable diag-targets must be set to loopback, device&loopback, or device&loopback,3.

The Sun part number for the parallel port loopback connector is 501-2965-01. 

eeprom@14,0

Tests the NVRAM functionality. 

fdthree

@14,3023f0

Tests diskette drive control logic and the operation of the drive. The test does not differentiate among a drive, media, or main logic board error; if any of these fail, it reports the diskette drive as the FRU. 

A formatted diskette must be inserted into the drive. 

network@1,1

Tests the on-board Ethernet logic, including internal and external loopback tests. 

To run external loopback tests on the TPE port, you must have a TPE loopback connector attached to the TPE port. The variable diag-targets must be set to loopback, device&loopback, or device&loopback,3.

The Sun part number for the TPE loopback connector is 501-4689-01. 

scsi@3 [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.]

Tests the on-board SCSI controller and SCSI bus subsystem for internal disk drives and removable media devices. Checks associated registers and performs a DMA transfer. 

scsi@3,1

Tests the main logic board external SCSI interface. Checks associated registers and performs a DMA transfer. 

se@14,40000

Tests serial port control and I/O logic, including internal and external loopback tests. The test checks I/O logic only if the external loopback test is enabled. 

Port A tests are not run if ttya is being used as the input/output device. 

To run external loopback tests, you must have a special passive loopback connector attached to each serial port, and the variable diag-targets must be set to loopback, device&loopback, or device&loopback,3.

There is one passive connector available for this test: Sun part number 501-4205-01. Use 501-4205-01 when ports A and B are not attached to external devices.  

su@14,3062f8

Tests keyboard control and input logic, including internal and external loopback tests. 

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. 

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)".

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.
