ERS8600 TMUX 6 Parity Question
« on: May 16, 2016, 09:11:19 PM »
I am new to the ERS8600 arena but have been tasked to find out the definition of what the Tmux 6 parity.

We have a situation that when one CPU is inserted into the Chasis the system runs fine. When we insert a secondary CPU, it runs for approximately 24 hours (until peak time) and then the system crashes.

What we have found is that the TMUX 6 Parity errors are extremely high when the two CPU's are inserted. When only one CPU is running it increments at a VERY slow rate, 10 a day.

But we don't know what the errors are or what the various columns mean.

Any help would be appreciated.

Here is the snapshot:

fabric 1
tmux 1 Parity 0 0 0 0
History 0 0 0 0 0 0 0 0
tmux 4 Parity 0 0 0 0
History 0 0 0 0 0 0 0 0
tmux 6 Parity 0 0 51 0
History 0 0 0 0 0 0 0 0
tmux 7 Parity 0 0 0 0
History 0 0 0 0 0 0 0 0
tmux 10 Parity 0 0 0 0
History 0 0 0 0 0 0 0 0

That is sounding like a hardware fault.  TMUX is the "tap MUX".  It is part of the internal data bus system of the 8600's.  If it is detecting lots of errors, you have a serious hardware issue with the unit.  Could be the specific CPU card or the chassis.  But Avaya support are the people to figure it out and RMA the hardware.
