Removing a Failed DSP-1000 Power Supply for the 6920 Array May Cause the Redundant Power Supply to Fail

1. Impact

Removing a failed DSP-1000 power supply for the Sun Storage 6920 array may cause a failure of the adjacent (redundant) power supply, resulting in loss of access to the array. DSP-1000 power supplies (for 6920) are NOT hot-swappable.

This issue can occur on the following platform:

• Sun Storage 6920 Array with DSP-1000 Power Supplies
