4.4 Cold Replacement
In cold replacement all business operations are stopped. Cold replacement is the act
of powering off the server and disconnecting input power. This is normally required
for safety when the inside of the server is accessed. The work of cold replacement
consists of the following three steps:
■ Section 4.4.1, “Powering the Server Off” on page 4-18
■ Section 4.4.2, “Powering the Server On” on page 4-19
■ Section 4.4.3, “Confirming the Hardware” on page 4-20
4.4.1 Powering the Server Off
