Expansion cards and backup units
9.5 Backup units (BBU/FBU)
The server offers different backup units depending on the used RAID controller:
– BBU (Battery Backup Unit)
– FBU (Flash Backup Unit)
The BBU/FBU backs up the memory contents of the RAID controller in the event
of a power failure. You can install one BBU/FBU.
Notes on BBU fixation
Former systems can be equipped with an old type chassis. In this case the BBU
fixation uses bolts instead of shoulder screw caps.
Neither the installation position nor the cable routing is different.
Required tools: Phillips PH0 / (+) No. 0 screw driver
