Urgency: Planned
Affected services:
- Cooling equipment BIT-2A (partial)
- BIT Office
Expected impact: Slight increase in temperature
Customer intervention required: No
Reference number: 164232

Summary:

We will be performing an upgrade of a sub-distributor.

Details:

During this maintenance, one of the three automatic transfer modules for the emergency power generators will again be replaced with a newer model. The previous maintenance didn't go as planned, so the module will be replaced again.
During the maintenance, the automatic transfer module in the sub-distributor for the BIT Office, one of the three chillers, downflow units (responsible for circulating cold air in the data centers) of BIT-2A and some control cabinets will be replaced.

This upgrade is necessary because the current model of automatic transfer module is no longer in production. In the event of an unexpected grid failure, this sub-distributor will be switched to generator power by hand.

The two sub-distributors which provide power to server room BIT-2A will be fully operational during this maintenance and will switch to generator power automatically in case of an unexpected grid failure.
The upgrade will be tested which will result in a restart of all computairs in serverroom BIT-2A. This may result in a slight temporary increase in temperature in the data center.

This maintenance will be supervised by BIT engineers.
