4. If you have a single-node server without a memory expansion module
attached, install the QPI wrap cards or fillers. If you have a two-node server
or if your server is connected to a memory expansion module, reconnect the
QPI cables.
5. Connect the following cables: front fan, scalability LED, operator information
panel, hard disk drive backplane, and CD/DVD power.
6. Route the front USB and DVD/CD signal cables behind the hard disk drive
backplane and to the side of the ServeRAID adapter connector (see “Internal
cable routing and connectors” on page 101).
7. (Trained service technician only) Reinstall the microprocessors (see “Installing
a microprocessor and heat sink” on page 165).
8. Install the memory-card cage (see “Replacing the memory-card cage” on page
176). Make sure that all the cables are clear of the cage as you install it in the
server.
9. Install the middle fan (see “Replacing the middle hot-swap fan” on page 123).
10. Connect the signal cables to the ServeRAID adapter and install the adapter in
the server (see “Replacing the RAID adapter carrier and the RAID adapter
assembly” on page 149).
11. Install the memory cards and memory-card fillers (see “Replacing a memory
card” on page 137).
12. Install the I/O-board shuttle (see “Replacing the I/O-board shuttle” on page
144). Be sure to thread the USB and DVD/CD signal cables through the server
and connect them to the I/O-board shuttle.
13. Install the top cover bracket (see “Replacing the top-cover bracket” on page
108).
14. Install the power supplies (see “Replacing the hot-swap power supply” on
page 127).
15. Install the top cover (see “Replacing the top cover” on page 107).
16. Connect the cables and power cords (see “Connecting the cables” on page 104
for cabling instructions).
17. Turn on all attached devices and the server.
18. Using the Advanced Settings Utility (ASU), restore the system configuration,
such as the IMM IP addresses, vital product data, and the machine type,
model number, and serial number of the server.
19. Using the ASU, restore the system configuration to the new microprocessor
board.
