The switch provides a facility for running normal or extended diagnostics.
In simple terms, a normal routine performs a simple ASIC and packet loopback test on all ports, and an extended routine performs extensive ASIC, ASIC-memory, and packet loopback tests. By running and viewing the results from diagnostic tests, you can detect and troubleshoot any hardware issues.
On BlackDiamond X8 and 8800 series switches, you can run the diagnostic routine on Input/Output (I/O) modules, management modules (MSMs/MMs), or Fabric modules (BlackDiamond X8 series only) without affecting the operation of the rest of the modules. The module under test is taken offline while the diagnostic test is performed. Traffic to and from the ports on that module is temporarily unavailable. When the diagnostic test is complete, the module is reset and becomes operational again.
Note
The diagnostics image is not included in the SummitX480 image. You must use the diagnostics.xmod to update the diagnostics image.Note
Before running diagnostics, you must power on the External Power Supply (EPS) when it is connected to the switch.Note
Before running slot diagnostics on a modular switch, you must have at least one MSM/MM installed in the chassis.When you run diagnostics on the SummitStack stacking ports, the switch completes a hardware test to ensure that the stacking ports are operational.
