Where: Orono Data Center
When: Apr 08, 2015 0500
Expected Duration: 1/2hr
Scope: DC-wide

Summary: 
	
This is a follow-up to the previous DC outage on March 11th.

The cause was found to be a design flaw in the PSUs used for the Nexus 5500.  The failed PSU was replaced immediately to ensure service availability.  The remaining 3 of 4 PSUs for the Cisco Nexus pair will be replaced during this maintenance window in response to Cisco Field Notice FN 63893. 

This maintenance is not expected to be service-affecting, but due to the nature of the design flaw for the PSUs being replaced we are performing the swap within a maintenance window.
