Confirmation after Installation/Removal
Confirm the following after installing an additional option or removing a
component:
!
Reinstalling removed components exactly as they were. Install the
components and cables that were removed and disconnected exactly as
they were. The server may malfunction if certain components are not
reinstalled or if cables are not connected properly. In particular, make
sure that the FPC cable (Figure 4-1, A) is firmly connected. Be sure to
securely install the components and connect the cables.
!
Confirming that no parts such as screws are left in the server.
Confirm that conductive parts such as screws are not left in the server.
Turning on the power with a conductive part in the system may cause
personal injury or equipment damage.
!
Confirming the cooling effect in the server.
Confirm that the ventilating holes are not covered with an internally
connected cable. Insufficient cooling raises the internal temperature,
which may cause the server to malfunction.
!
Confirming operation with a tool.
Some installed option boards or devices require running a diagnostic
utility or BIOS SETUP to verify proper installation. For details, see the
procedure for installing the option boards or devices.
