Removing a PCI express riser-card assembly: 2145-DH8

Use these instructions when you are prompted to remove a PCI express riser card assembly from a SAN Volume Controller 2145-DH8 node.

About this task

The SAN Volume Controller 2145-DH8 system has two PCI riser-card slots on the system board. The following information indicates the riser card slots:

• The 2145-DH8 comes with two PCI Express riser-card assemblies installed.
• PCI riser slot 1  1  (the slot farther from the power supplies). You must install a PCI riser-card assembly in slot 1. See Figure 1.
• PCI riser slot 2  2  (the slot closer to the power supplies). You must install a PCI riser-card assembly in slot 2.
• Cards in PCI riser slot 2 are usable only if microprocessor 2 is also fitted.
