MSM Connection Broken
<CRIT:SYST> The connection between MSM-A daughter board and I/O module 2 is broken,
need to fix immediately
Software Version
All ExtremeWare versions
Hardware Version
BlackDiamond
Explanation
This message indicates that the backplane connection between MSM A and the I/O module in slot 2 is
broken. One of the two modules is bad. This can be faulty hardware or a seating problem with the
modules.
Action
1 Remove and re-insert the affected I/O module and MSM.
2 If the problem persists, replace the I/O module.
3 If the problem persists, re-insert the I/O module and replace the MSM.
If the same message is logged for multiple I/O modules, replace the MSM.
Incorrect seating of one or both of the MSMs can cause connectivity problems between the MSMs and
the I/O modules. This can cause a variety of errors to be entered in the system error log. A badly seated
MSM can even cause the switch to hang or reboot.
You must properly seat all modules. Insert modules in the following order:
1 MSM A
2 MSM B
3 I/O modules
If you have an MSM32 seating problem, you might see some of the following additional errors:
<CRIT:SYST> The broken connection between MSM-A daughter board and I/O module 1 is
recovered
<CRIT:SYST> The connection between MSM-A daughter board and I/O module 4 is broken,
