have to apply extra downward pressure to make sure that it is completely in
place.
23. Connect the SCSI signal cable to the connector on the SCSI adapter in slot 1
on the riser-card assembly.
24. Install the riser-card assembly. Arrange the excess length of the SCSI signal
cable so that it does not block airflow to the heat sink in the area, if possible.
25. Make sure that all cables avoid the fan connectors and the power-backplane
system-board connector (see “Power-backplane-board connectors” on page 18
and “System-board internal cable connectors” on page 19).
26. Install the fan-bracket assembly.
If you have other optional devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 81.

To remove a tape drive from the server, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 28.
2. Turn off the server and peripheral devices, and disconnect the power cords
and all external cables.

than IBM service technicians are authorized to connect or disconnect power to
the dc power supply. See the documentation that comes with each dc power
supply.
3. Remove the cover from the server.
4. Remove the fan-bracket assembly (see “Removing the fan-bracket assembly”
