Symptom-to-FRU index
The Symptom-to-FRU index (Table 17) lists symptoms and the possible causes. The
most likely cause is listed first.
The PD maps found in the IBM TotalStorage DS4000 Problem Determination Guide
also provide you with additional diagnostic aids.
Notes:
1. Always start with the “General checkout” on page 21. For IBM devices not
supported by this index, see the manual for that device.
2.
Do not look directly into any fiber cable or GBIC optical output. Read “Notices”
on page 137. To view an optical signal, use a mirror to view the reflected light.
