• Replace the transceiver with a transceiver of the same type
(shortwave or longwave) and speed.
• Perform an external loopback test ( Performing loopback tests on
page 175).
NOTE: Event code 514 may generate a call-home event that incorrectly
indicates a CTP card failure. Although the optical socket on the CTP card may
have failed, replace the transceiver and verify operation. If a failure is still
indicated, replace the CTP card (
RRP: CTP card on page 213).

A port card failed and the card must be replaced (
RRP: Port module
card (UPM and XPM) on page 218).
• This procedure is concurrent and can be performed while
director power is on.
• Verify the location of the failed card. Figure 49 and Figure 50
show UPM (or XPM) card numbers (0 through 34), port numbers
(00 through 139), and bolded logical port addresses.
• 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
