Chapter 9 Switch Operating Procedures
Managing PXM1E and AXSM Card Diagnostics
AXSM cards run offline diagnostics in the following areas:
• Processor subsystem: NVRAM and BRAM
• ASIC tests: Atlas (register test, ingress memory, egress memory) and framer (register test)
PXM1E cards run registered offline diagnostics on UI- S3 or UI-S3/B back cards.
Both control path and data path must to be tested in order to have complete test coverage on the entire
connection path within a card. The control path is the path that carries IPC messages between cards. The
diagnostic data path is the path for cells travelling between the backplane and the loop back device.
Configuring Offline and Online Diagnostics Tests on PXM1E and AXSM Cards
Enter the cnfdiag command as follows to enable online diagnostics tests on PXM1E or AXSM cards:
MGX.7.PXM.a > cnfdiag <slot> <onEnb> <offEnb> [<offCover> <offStart> <offDow>]
Table 9-35 tells you how to set these parameters to run online diagnostics tests on PXM1E and AXSM
cards.
Warning Do not remove the active PXM while the offline diagnostic is running on the redundant PXM. If you
remove it, the redundant PXM reboots but will not be able to become active unless its hard disk drive
was previously synchronized to the hard disk on the previously active PXM.
Example 9-1 Configuring online diagnostics only
In the following example, the user enables online diagnostics only for the PXM1E in slot 7.
MGX.7.PXM.a > cnfdiag 7 enable disable
