www.dell.com | support.dell.com diag stack-unit s Run offline diagnostics on a stack unit. Syntax diag stack-unit number [alllevels | level0 | level1 | level2] verbose testname Parameters number alllevels level0 level1 level2 verbose testname Enter the stack-unit number. Range: 0 to 7 Enter the keyword alllevels to run the complete set of offline diagnostic tests. Enter the keyword level0 to run Level 0 diagnostics. Level 0 diagnostics check for the presence of various components and perform essential path verifications. In addition, they verify the identification registers of the components on the board. Enter the keyword Level1 to run Level 1 diagnostics. Level 1 diagnostics is a smaller set of diagnostic tests with support for automatic partitioning. They perform status/self test for all the components on the board and test their registers for appropriate values. In addition, they perform extensive tests on memory devices (e.g., SDRAM, flash, NVRAM, EEPROM, and CPLD) wherever possible. There are no tests on 10G links. At this level, stack ports are shut down automatically. Enter the keyword level2 to run Level 2 diagnostics. Level 2 diagnostics is a full set of diagnostic tests with no support for automatic partitioning. Level 2 diagnostics are used primarily for on-board loopback tests and more extensive component diagnostics. Various components on the board are put into loop back mode, and test packets are transmitted through those components. These diagnostics also perform snake tests using VLAN configurations. You must physically remove the unit from the stack to test 10G links. Enter the keyword verbose to run the diagnostic in verbose mode. Verbose mode gives more information in the output than standard mode. Enter the keyword level2 to run a specific test case. Enclose the test case name in double quotes (" "). For example: diag stack-unit 1 level1 testname "first" Defaults None Command Modes EXEC Privilege Command History Version 8.3.1.0 Version 7.7.1.0 Introduced the verbose option. Introduced on S-Series offline stack-unit s z Place a stack unit in the offline state. Syntax offline stack-unit number Parameters number Enter the stack unit number. Range: 0 to 7 Defaults None 1554 | S-Series Debugging and Diagnostics
