TSW board troubleshooting
Indications of problems with TSW boards may come from three sources:
• LEDs on the TSW board.
• The 16-character scrolling display near the bottom of the TCM board.
• The Enterprise Manager alarm log.
Action Remove and reseat the board. Verify that the latch
mounting screws are tightened to the proper torque. If the
fault persists, try to determine the source of the fault by
interpreting the interval pattern of the Heartbeat LED (see
TCM/TFIO/TSW PROM boot blink codes and TCM/TFIO/
TSW board boot blink codes). Error conditions on the
board are indicated by a three-second delay when the LED
is not lit, followed by a specific distinctive rapid blink interval
rate pattern. Document your findings, and then replace the
board. Place the failed board in an antistatic bag, and
return it to IBM.
Error LED is Blinking on a Port
Problem Summary An error condition has occurred with a port connection. An
error condition is reported on the Enterprise Manager.
Probable Cause A port may be faulty, the board may not be seated properly.
Action Verify that the SPF installed in the port is firmly connected.
Verify that the fiber cable is firmly connected to the SFP.
Remove and reseat the board. Verify that the latch
mounting screws are tightened to the proper torque. If the
fault persists, try to determine the source of the fault by
interpreting the interval pattern of the Error LED associated
with the port (see TFIO Port Blink Codes). Error conditions
on the board are indicated by a three-second delay when
the LED is not lit, followed by a specific distinctive rapid
blink interval rate pattern.
