SNET diagnostics

The following table describes the tests in the SNET diagnostic test menu.

Note: Tests that are labeled [Xtnd] often require loopback plugs for complete test operation and will indicate failures without these plugs.

Caution: Do not run [Xtnd] mode diagnostics on network adapter cards with live network connections. Disconnect all network connections prior to running network diagnostics in [Xtnd] mode. Running with attached networks can adversely affect other attached devices. Type xtnd n to cancel Extended test mode.

Test no	Test	Description
1	Comprehensive test	Runs all tests in this menu in current mode.
2	PCI register test	Verifies the PCI configuration registers.
3	Software reset test	Verifies the software reset function, checks the SAIL registers after reset, and verifies default values of all internal registers.
4	Interrupt test	Tests the interrupt mechanism. Transmit and receive interrupts are checked, as well as timer interrupts.
5	Link test [Xtnd]	Extended test mode: Verifies external link signals. Requires loopback plug.
6	Internal loopback BTE0	Tests data movement between main memory and the SNET card, using on-chip loopback capability.
7	Internal loopback BTE1	Tests data movement between main memory and the SNET card, using the on-chip loopback capability. Checks data transfers.
8	External loopback BTE0 [Xtnd]	Extended test mode: Tests data movement between main memory and the SNET card and through the two external interface ports (X and Y). Checks short data transfers. Requires loopback plug.
9	External loopback BTE1 [Xtnd]
71	Display chip info	Displays information about the chip.
72	Cable check [Xtnd]	Extended test mode: Checks the cable connection to the card. Requires loopback plug.
90	SNET card selection	Enables selection of the SNET card for testing.
91	Enable/disable looping	Enables or disables continuous running of a diagnostic test. The test is stopped when Ctrl-C is pressed or when an error is encountered if option 92 is active.
92	Stop/continue on error	Starts or stops running a diagnostic test on an error. If looping is enabled, as set by option 91, looping continues after an error is encountered.
93	Extended/normal test mode	Enables or disables extended mode on tests where extended mode is an available option.
99	Exit	Exits diagnostics.
