Power System Maintenance

[Dean]

This E-Mail is to alert you about maintenance we will be performing.


Start time (Eastern): Thursday 9:00 AM 4/20/06

End time (Eastern): Thursday 12:00 PM (Noon) 4/20/06


We have been notified by Eaton (PowerWare) maker of our new 120KVA UPS that they have a recall on the 9390 control board. During this maintenance window, a PowerWare Engineer will be replacing the recalled control board. In order to replace the control board the UPS has to be placed in maintenance bypass mode and turn off. By placing the UPS in maintenance bypass mode the power will be unconditioned and unprotected by the UPS, direct feed from the utility (OUC).

As a precautionary measure and since a direct utility feed can be inconsistent, we have decided to supply the utility feed with the Generator vs. OUC. The Generator power is more consistent and stable than the utility. The utility feed will also be available in the event there is or become any issues with the Generator.

Although we don't anticipate any power loss or service interruptions, our Support team will be closely monitoring your service(s) to ensure that this planned maintenance causes as little interruptions to your service(s) as possible.

Again, this work should not affect your service.
