Purpose:

SSPA Core Site HVAC Power Tie-In on April 16, 2021 from 5 - 6am

Purpose:

Services Affected:

On 4/16/21, Facilities Management (FM) will be installing a new breaker on the main Emergency (E) Power panel for the building to support our HVAC unit in the Core site. The work will commence at 5 AM, at which point the panel will be shut off; the outage will last around 45 minutes to an hour, and Alex Giesler will be onsite during the work to ensure that the UPS batteries are not being completely exhausted. The batteries are new, so they should last longer than the outage of the E panel, but there is a chance that the work could go longer and the UPS will lose power as it's batteries are spent. There will be mitigation plans in place for this possibility, and it has already been communicated to the various groups involved to alert them of the work.

Once the breaker and wiring are landed on the E panel, the power will be restored and function as normal.

If you have any questions, please call Alex Giesler at 949-824-9494.
