Note: When you disconnect the power source from the server, you lose the
ability to view the LEDs because the LEDs are not lit when the power
source is removed. Before you disconnect the power source, make a
note of which LEDs are lit; then, see the
Problem Determination and
Service Guide for information about how to solve the problem.

9. Touch the static-protective package that contains the new ServeRAID-MR10i
SAS/SATA adapter to any unpainted surface on the outside of the server; then,
grasp the adapter by the top edge or upper corners of the adapter and remove
it from the package.
