Removing the system board
To remove the system board, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 141.
2. Turn off the server and all attached devices; then, disconnect all power cords
and external cables.
3. Turn the server on its side so that it is lying flat, with the cover facing up.
4. Unlock and remove the side cover (see “Removing the side cover” on page
145).
5. Note where each cable is connected; then, disconnect all cables from the
system board.
6. Press and hold the drive cage release tab; then, rotate the drive cage out of
the chassis until the retaining tab on top of the cage locks into place.
7. Remove any of the following components (in addition to others that might not
be listed) that are installed on the system board and put them in a safe,
static-protective place:
v Adapters (see “Removing an adapter” on page 151).
v SAS/SATA controller (see “Removing a ServeRAID-BR10il v2 SAS/SATA
controller” on page 204).
v Virtual media key (see “Removing the virtual media key” on page 181).
v Microprocessor and fan sink (see “Removing the microprocessor and fan
sink” on page 209).
v DIMMs (see “Removing a memory module” on page 168).
v Battery (see “Removing the system battery” on page 183).
v SAS/SATA controller (see “Removing a ServeRAID-BR10il v2 SAS/SATA
controller” on page 204 ).
v Hypervisor key (see “Removing a USB embedded hypervisor flash device”
on page 180).
v The fan connector covers.
8. Remove the four screws that secure the fan sink retention module and fan sink
mounting bracket to the system board; then, set the fan sink retention module,
fan sink mounting bracket, and screws aside for use later.
Note: Make sure that you observe the orientation of the fan sink retention
module before you move it so that when you reinstall it, you install it in the
same orientation.
