Service History

The original batteries finally gave up in September 2015, a fresh set (RBC 24) were ordered and fitted a week later. Tip - you can reuse the battery tray, you only need order the actual lead acid batteries (x4).

Current location

As of 2019 Derrick is still functional and is in the server rack as it's UPS. Maintenance is expected to be required within the next year or a replacement will have to be found. As part of the computing update 2019 / 2020 Derrick may be replaced when the server stack is altered and replaced with VMs. At time of writing, the 2019 /2020 computing update hasn't happened yet and so Derrick's fate is unknown.
