Fiber Channel Switch 2109 S16 01 23 4 7 8 9 10 13 14 15 5 6 12 11 Figure 37. Switch setup to run crossPortTest SJ000063 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. Display test Pressing Enter while the Display test command is selected displays a series of test characters. Use this test to determine that the display is functioning properly. Display test long Pressing Enter while the Display test long command is selected causes a series of test characters to display. Use this test to determine that the display is functioning properly. Memory test Pressing Enter while the ramTest command is selected activates the display shown in Figure 38. System Memory Test at 0x1021d460 len 13091456 Figure 38. System memory test If the memory test is OK, the front panel activates the display shown in Figure 39 on page 99. 98 IBM SAN Fibre Channel Switch: 2109 Model S16 Installation and Service Guide

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.
Display test
Pressing Enter while the
Display test
command is selected displays a series of test
characters. Use this test to determine that the display is functioning properly.
Display test long
Pressing Enter while the
Display test long
command is selected causes a series of
test characters to display. Use this test to determine that the display is functioning
properly.
Memory test
Pressing Enter while the
ramTest
command is selected activates the display shown
in Figure 38.
If the memory test is OK, the front panel activates the display shown in Figure 39
on page 99.
