NOTE:
The TBBU on the PERC 6/E adapter consists of a DIMM and battery backup
unit.
This section describes how to remove the TBBU from a PERC 6/E adapter
that is currently installed in a system.
1 Perform a controlled shutdown on the system in which the PERC 6/E
adapter is installed, as well as any attached storage enclosures, and remove
the PERC 6/E adapter from the system by following the instructions
detailed in "Removing the PERC 6/E and PERC 6/i Adapters" on page 50.
2 Visually inspect the controller and determine whether the dirty cache LED
on the DIMM is illuminated. See Figure 4-9. If the LED is illuminated,
reinsert the controller into the system, replace the system cover, reconnect
the system to power, turn the system on and repeat
step 1
