Step 3.
Remove the Optional BBU and charger board–
If a BBU has been installed on
the IO board, both the BBU and the charger board should be removed. To
remove the BBU disconnect the BBU connector from the battery charger. Note:
the retention screws that connect the BBU to the IO board were removed in
Step

above. Once the BBU has been removed, gently pull the charger board in an
upward direction until the board-to-board connectors are separated from those
on the controller board. (See
Figure 2-1
)
Step 4.
Remove the Interface Retention Screws
- There are also retention screws on the
rear panel of the controller module that connect the six channel expansion port
SCSI connectors and the RS-232C serial port that are connected to the host IO
board, to the rear panel of the controller module.
Remove all these retention
screws
. See
