F) Removing The Supercap Battery Backup; Figure 14: Removing The Battery Backup - Kontron CG2300 Installation And Maintenance Manual

» Fan Control Board Power cable, which provides power from the PDB (soldered) to the FCB and the six fans
For the location of the FCB power connector (J9A2) on the FCB, see Figure 43 in Section 5.2.17.
Before you can disconnect the FCB PWR/SIG cable (part of FPB multifunction cable), the FCB power cable, and the three fan pair
cables from the FCB, you need to remove everything that is in the way for working on the FCB: the support cross bar, the
baseboard power cable bundles, and the cable bracket/fan cage assembly. For instructions, see (D), (E1), and (G) in Chapter 4.

(F) Removing the SuperCap Battery Backup

The optional RAID battery backup, if installed, has to be removed to install or remove components on that area of the baseboard,
such as installing an eUSB module, or removing the support cross bar, as it is one of the components attached to the cross bar.
Installing the SuperCap battery backup module entails fastening it to the support cross bar. For that reason, it has to be removed
anytime the cross bar is removed. Figure 14 shows the location of the battery backup module as installed on the cross bar. Figure
31 shows how the battery backup is connected to the hardware RAID controller, so it can be disconnected.
Before you can disconnect the battery backup module from the baseboard, you must first remove the chassis cover and the left
riser card assembly. For instructions, see (A) and (B1) in Chapter 4.
To remove the battery backup module:
1. Loosen the captive screw that fastens the battery backup to the support cross bar. (Figure 14, "A")
2. Lift the assembly up and out of the chassis. ("B")
