Removing the riser-card assembly
The server comes with one riser-card assembly that contains two PCI Express x8
connectors. You can replace the riser-card assembly with one that contains two
PCI-X 64-bit 133 MHz connectors that support single-width IXA adapters.
To remove the riser-card assembly, complete the following steps.
1 Access holes
2 Release tabs
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 53.
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. Pull the server out of the rack.
4. Remove the cover (see “Removing the cover” on page 56).
5. Push the two retention latches on the riser-card assembly toward the low-profile
PCI slots; then, grasp the assembly at the rear and side edges and lift it to
remove it from the server. Place the riser-card assembly on a flat,
static-protective surface.
