Dell PowerEdge FX2/FX2s - Manual (Page 272)

level0 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.
level1 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 (for example, SDRAM, flash, NVRAM,
EEPROM, and CPLD) wherever possible. There are no tests
on 10G links. At this level, stack ports are shut down
automatically.
level2 Enter the keyword level2 to run Level 2 diagnostics. Level 2
diagnostics are 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 Loopback mode and test packets are transmitted
through those components. These diagnostics also perform
snake tests using VLAN configurations. To test 10G links,
physically remove the unit from the stack.
verbose Enter the keyword verbose to run the diagnostic in Verbose
mode. Verbose mode gives more information in the output
than Standard mode.
no-reboot Enter the keyword no-reboot to avoid automatic rebooting
of the chassis after completion of diagnostic execution.
Generally, this option is never used because if you run the
diagnostic once again without rebooting the chassis, it may
cause an issue with the diagnostic results..
terminate Enter the keyword terminate to stop the execution of the
level diag that is already started using the diag stack-unit
command. Once this CLI is issued, syslogs indicating the
termination of the diag test is displayed. The diag results for
the executed tests are stored in the flash directory
(TestReport-SU-X.txt).
interactive Enter the keyword interactive to run some individual
diag tests such as POWERLEDTEST, STATUSLEDTEST and so
on. The help option under the interactive command displays
the list of tests that can be run.
Defaults none
