3. Insert the power unit into the power unit slot. As the power unit can be made
redundant, there are two slots, left and right. When using only one power unit,
insert the power unit into the slot #0 that is on the left-hand side facing the
main unit. When inserting the power unit, make sure you securely hold the
power unit with both hands (as shown in
Figure 10-6 )and insert it all the way
in until it is secure.
