Display the crossbar error counters for switch ASIC 2 in slot 7. The Node Alarm field of the display
shows the errors have resulted in a critical al arm . A la rge nu mb er of er ro r s have o ccu rre d i n th e sl ot 12
link. Many of the errors are parity or CR C rel at ed , but t he on e er ror th at i s mos t seri o us is l oss o f sy n c.
With a loss if sync between the service module and the switching fabric , many other, compar atively less
significant errors are possible.
Note at the bottom of the display a message about multipliers for large numbers of errors. Because the
display can accommodate a finite number of errors without being distorted, a K (for 1000) and M (for
1000000) multiplier may be n eces s ar y, as this ex am p le sh ows.
