System bus diagnostics
Checking the Meridian
Mail system bus
The Meridian Mail system bus is controlled by the Utility
card located in Node 1. A fault on the system bus can cause
all communication between nodes to be lost. If you suspect a
system bus problem, follow these steps.
Step Action
1 If Utility card diagnostics failed on Node 1, replace
the Utility card.
2 Verify that all cards are properly seated.
3 Observe the BootROM diagnostics messages on
Node 1. If you do not see the Tap Register test or the
Tap Dataline test in the BootROM messages,
replace the Utility card. If the problem persists,
replace the Enhanced MMP40 or MMP40 CPU card.
4 Replace the Utility card in Node 1.
5 Power on the system.
