IBM 2109 - SAN Fibre Channel Switch Model S16, Service Manual

Page: 114 / 178

Note: All ports on the switch must be connected or else the switch shows an error
condition. When running the crossPortTest command, you must set the
operating mode value to 0 or 1. Modes 2 and 3 do not send out the
extended link parameters (ELP) used to discover switches. If the ELP is not
sent, the switch does not know that the port is connected to another port on
the same switch and the test fails.
If an error is encountered during the test, the error displays on either the front panel
display or during the Telnet session.
Related error messages: DIAG-INIT, DIAG-PORTDIED, DIAG-XMIT,
DIAG-TIMEOUT, DIAG-ERRSTAT, DIAG-STATS, DIAG-PORTWRONG, DIAG-DATA,
DIAG-PORTABSENT.
