Chapter 11 Replacing a Server or Replacing Individual Components 11-7
11.4 Replacing the DVD or CD-ROM Drive,
Cable, and Paddleboard
Caution – The procedure below is for the attention of qualified service engineers
only. Before touching or replacing any components inside the server, disconnect all
cables and follow the instructions in Section 4.2, “Opening the Server” on page 4-4
which tell you how to open the server. Always place the server on a grounded ESD
pad and wear a properly grounded antistatic wrist strap.
1. Open the server by following the instructions in Chapter 4 (“Opening the Server”
on page 4-4).
Make sure all external cables are disconnected and pay particular attention to the
information about how to prevent electro-static discharge from your body from
damaging the components of the server.
2. With the system open and seated on top of an ESD pad, and with a properly
grounded antistatic wrist strap on your wrist, do the following:
a. Remove the old DVD or CD-ROM drive from the chassis (see Section 4.4.2,
“Removing a DVD or CD-ROM Drive” on page 4-9).
b. If you have a full-length PCI card installed, remove it (see Section 4.6.2,
“Removing a PCI Card” on page 4-14).
3. Disconnect the memory card reader board’s power cable from the system board
(see FIGURE 11-3 ).
4. From the chassis base, unscrew the plastic bracket that secures the paddleboard
(and that also provides support for a full-length PCI card).
5. Lift the paddleboard (with its ribbon cable) out of its guides at the back of the
DVD or CD-ROM drive enclosure and discard it.
6. Connect the new IDE ribbon cable to the system board with the cable extending
away from the system board and towards the DVD or CD-ROM drive (see
FIGURE 11-3 ).
7. Now connect the ribbon cable to the connector on the paddleboard.
8. Insert the paddleboard into the guides at the back of the DVD or CD-ROM drive
enclosure in the chassis.
Do not replace the plastic bracket yet.
