PCI riser card
The following illustration shows the location of the adapter expansion slots 1 on
the PCI riser card.
Note: For clarity, the PCI riser-card assembly is inverted in the illustration.
To install an adapter, complete the following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 7.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables.
Attention: In a dc power environment, only trained service personnel other
than Lenovo 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. Determine which expansion slot you will use for the adapter. If you are installing
an adapter in PCI slot 1 or 2, remove the PCI riser-card assembly.
