5-2 Installing the Intelligent Battery Backup Unit
5.1 Installing the iBBU
on the ServeRAID M5025 Controller
The iBBU is compatible with systems that offer auxiliary power. Battery
charging and recharging take place automatically. The iBBU mounts
directly to the ServeRAID M5025 controller using a small board-to-board
connector (daughtercard).
Figure 5.1 displays the top view and the bottom view of the card. (The
“top” side is the side you can see after you install the iBBU on the RAID
controller.) Note that this unit combines a battery pack with a
daughtercard.
