We have been notified by London Data eXchange that they will be carrying out further work to increase the UPS capacity at the LDeX2 facility between 09:00 and 17:00 on 28/11/2019 and 29/11/2019.
This work will involve a period where each of the UPS systems needs to placed into bypass whilst the new modules are brought into service and as such the LDeX2 facility will be operating as a level of reduced redundancy for some periods whilst this work is being carried out. As such, all services hosted in LDeX2 should be considered "at-risk" for the duration of this work.
Whilst in bypass, any equipment connected to the feed supplied by that UPS unit will be running on generator power and as such should be considered at-risk in case there is an issue with the generators. Utility mains power will remain available throughout the maintenance work as a backup if required.
This maintenance work will be carried out on both the A-side and B-side UPS systems separately. At no point will both systems be under maintenance simultaneously.
All devices with dual power supplies should be connected to both the A-side and B-side PDUs, so in event of any problems on one of the feeds will still have the other feed available. All devices with single power supplies should be fed from our in-rack ATS units, which can switch between the two feeds fast enough that connected devices do not see any loss of power.
If you have any questions or if you wish to double check how your devices are connected, please don't hesitate to get in touch with our helpdesk in the usual manner.
