Serial Bus faults can be caused by:

●

A defective circuit pack inserted into one of the G650 slots

●

Bent pins on the G650 backplane

●

Defective TDM/LAN bus cables

●

Power supply microcontroller failure

●

TN2312BP IPSI failure

It is possible that a circuit pack can cause a Serial Bus fault and still exhibit trouble-free 
operation. For example, insertions of any circuit pack into a G650 slot may bend the backplane 
pins and short two leads together. Or a circuit pack that doesn’t use the Serial Bus could still 
have an on board short that shorts one of the Serial Bus leads. Since the Serial Bus is a shared 
resource that each circuit pack and power supply has access to, identification of the cause of a 
Serial Bus fault can be difficult.

!

WARNING:

Since the Serial Bus fault isolation procedure involves removing circuit packs and 
possibly disconnecting entire carriers, the procedure is extremely destructive to 
the port network that is being tested. If possible, arrange to perform this 
procedure at a time when traffic is minimal.

As circuit packs are removed or entire carriers are disconnected, any active calls terminating on 
those circuit packs or carriers will be dropped. If you have any hints about a particular circuit 
pack that may be causing the Serial Bus problem investigate those before performing this 
procedure (for example, look at any circuit packs that were inserted into the PN just before the
