[DC3] Preventive maintenance of CRAC units
Scheduled for Jun 14, 08:00 CEST  -  Jun 25, 18:00 CEST
Scheduled
We will carry out the semi-annual preventive maintenance of CRAC units according to the schedule below.
CRAC units will be shut down one at a time, so as not to impact the cooling of halls.

Each IT zone has CRAC unit called «backup»: each CRAC unit is doubled.
Each MVLB hall has a main air hanling unit (AHU).

The maintenance will be done according to the following schedule:
• MLVBs : 21/06/2021to25/06/2021
• Operators halls : 21/06/2021 and23/06/2021
• IT halls n°4 : 17/06/2021 and18/06/2021
• IT halls n°3 : 16/06/2021 and17/06/2021
• IT halls n°2 : 14/06/2021 and15/06/2021
• IT halls n°1 : 14/06/2021 and15/06/2021

The maximum cut-off time per CRAC unit is otherwise defined at 1 hour.

As a result, we will experience a loss of cooling redundancy during the preventive maintenance operation of a CRAC unit (max 1h).
No impact on the cooling of facilities.
