Removing Power
Error messages are stored in RAM and are lost when power is removed from
the switch. Access the error message log to view any error messages before
removing power from the switch. When all data transferring processes external
to the switch complete, removing power from the switch does not disrupt the
fabric.
Power-On Self-Tests
Table 5-1 lists the diagnostic tests automatically run during the Power-On
Self-Test (POST).
Table 5-1
POST Tests
Test Name Description Telnet Command
Memory test Checks processor RAM memory ramTest
Port Register test Checks the ASIC registers and SRAMs portRegTest
Central Memory test Checks the motherboard SRAMs centralMemoryTest
CMI Conn test Checks the CMI bus between ASICs cmiTest
CAM test Checks the CAM camTest
Port Loopback test Checks all of the switch’s hardware
(frames are transmitted, looped back,

NOTE:
POST execution after a cold boot executes the long version of the Memory test,
while POST execution after a warm boot executes a shorter version of the Memory test. A
switch rebooted with POST disabled generates the DIAG-POST_SKIPPED error log
message.
Diagnostic Tests
The following tests are available from the switch front panel. For detailed
information on executing diagnostic tests through a Telnet session, refer to the
Compaq StorageWorks SAN Switch Fabric Operating System Management
Guide or the Compaq StorageWorks SAN Switch QuickLoop Management
Guide that came with your switch.
