Note – Boards should be removed by pulling outward using the front handle with
one hand and placing the other hand underneath the bottom guide rail for
additional support. Carry the board by the front handle to a work area holding it
vertically, with the connector downward. Lift the board and place the other hand
under the bottom, or back, of the board placing the bottom, or back, on an ESD-
protected surface. Never place the weight of a board on its connector as it is easily
damaged.
4. To gain additional access to the power cable, remove board sets and carrier plates
from slots 5, 6, 7, and 8 front (side 0) or slots 14, 15, 16, and 17 rear (side 1).
Remove additional carrier plates, as needed.
5. Disconnect the power cable connector and the control ribbon cable connector from
the fan backplane. See
