IB diagnostics

The following table describes the tests in the IB diagnostic test.

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	Controller chip test	Test controller chip register access.
3	EEPROM CRC check	Reads and verifies the EEPROM CRC data.
4	Onchip RAM test	Test ERP RAM on the controller chip.
5	Interrupt test	Tests the interrupt mechanism.
6	Internal loopback test	Test data transfer between host memory and IB card, using onchip loopback.
7	Link test [Xtnd]	Extended test mode: Verify external link status. Point to point cable needed.
8	External loopback test [Xtnd]	Extended test mode: Test data transfer between host memory and IB card, using external loopback. Point to point cable needed.
70	Display card information	Display card vendor ID, device ID, Revision ID, class code and GUID base.
71	Reset chip	Resets the controller chip.
90	IB card selection	Enables the selection of IB 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 looping 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.
