Test the ASAP Card

Step 1 Determine whether you are experiencing trouble on a single SFP (PPM), on all PPMs within a
4PIO (PIM), or on all 4PIO used in that ASAP card. If there is only partial failure, you might be able to
replace this part rather than the entire card.
If the errors are being observed on one port but not all ports of the ASAP, you might only need to replace
Step 2
that SFP (PPM). Remove the errored SFP (PPM) and replace it with a known-good SFP (PPM) by
completing the procedures for this in the "Install Cards and Fiber-Optic Cable" chapter of the
Cisco ONS 15600 SDH Procedure Guide.
If all SFPs (PPMs) on a particular 4PIO (PIM) are experiencing problems, the 4PIO (PIM) is indicated.
Step 3
Remove this 4PIO (PIM) and replace it with a known-good one using the procedures for this in the
"Install Cards and Fiber-Optic Cable" chapter of the Cisco ONS 15600 SDH Procedure Guide.
Step 4 If the trouble still is not located, complete the
suspected bad ASAP card and replace it with a known-good one.
Step 5 Resend test traffic on the loopback circuit with a known-good card.
Step 6 If the test set indicates a good circuit, the problem was probably the defective card. Return the defective
card to Cisco through the RMA process. Contact Cisco Technical Support (1 800 553-2447).
