BayStack 303 and 304 Switch-related Issues
The BayStack switches have a powerful set of system diagnostics that check all
internal resources of a switch whenever it is turned on. After the master core
processor (management processor) has tested itself, each port is tested in
sequence. The switch attempts to transfer Ethernet packets only if all diagnostic
tests complete without errors.
