DVD and CDR/W Drives on Sun Blade 2500 May Not Power Up

---

Impact

Due to incorrect jumper settings, DVD and CDR/W drives on Sun Blade 2500 systems that were shipped between 01-Mar-2004 and 01-May-2004, may not power up after the workstation recovers from "Power Management Mode".

Contributing Factors

This issue can occur on the following platform:

SPARC Platform

• Sun Blade 2500

This issue only occurs on Sun Blade 2500 systems (shipped between 01-Mar-2004 and 01-May-2004) that have the jumper setting on the drive set to "Slave" or "Cable Select".

Note: Drives with the jumper set to "Master" will not experience this issue.

To verify if a system is vulnerable to this issue, a visual inspection of the drive is required to determine the jumper settings.
