Maintenance Analysis Procedures (MAPS)
• Verify the location of the failed port. Figure 3-2 and Figure 3-3
show UPM card numbers (0 through15), port numbers (00
through 63), and bolded logical port addresses (hexadecimal 04
through 43).
• Notify the customer that all ports on the defective card are to be
blocked. Ensure the customer system administrator quiesces
Fibre Channel frame traffic through any operational ports on the
card and sets attached devices offline.
• Perform an external loopback test for all ports on the
replacement card as part of FRU removal and replacement
(
Performing Loopback Tests on page 4-21).
• Perform the data collection procedure as part of FRU removal
and replacement (
Collecting Maintenance Data on page 4-32).
