ses.psu.coolingReqError

Severity: ALERT
Description: This message occurs when the installed power supplies are placed so that air flow requirements of the disk shelf are not met. Placement of power supplies and their integrated fans is part of the disk shelf cooling and air flow design.
Corrective Action: Install power supplies in the indicated slots, cable to a power source, and turn them on. If the ses.psu.powerReqError is not presently posted for the system, an existing supply in the shelf can be moved to fill the required slot. A new instance of the error can be ignored while the supply is moved, but it should clear within a few minutes. If it does not, the condition must be corrected.
