Installing the RAID board
The following steps describe how to install the RAID board. The steps are the same for both the
2.0 and 2.5 versions of BCM1000 hardware, except for the power connections, which are
described in
“Routing power for mirrored systems” on page 256 .
1 Prepare the base unit for maintenance. Refer to “Shutting down the system software” on page
238 and “Shutting down the system hardware” on page 239 , if necessary.
2 Attach one end of the grounding strap to your wrist and the other end to a grounded metal
surface.
3 Disconnect all power and ribbon cable connections from the hard disk and the media bay
module back plane.
4 Remove the front cover.
5 Remove the blank slot cover.
6 Insert the RAID board into the slot in the housing so that the end with the LEDs fits through
the open card slot.
Ensure that you insert the board, so that the bottom tab fits into the open slit at the bottom of
the card slot.
7 Clip the back end of the RAID board to the middle shelf of the media bay module housing.
Refer to
Figure 113 .
Figure 113 Clip the RAID board onto the media bay module housing
Note: This clip holds the board to the media bay module housing. If the clip is not
engaged, you risk breaking the RAID board. The spacer tab, located above the clip, must
rest against the outside of the media bay module housing to provide support for the board.
