Oracle X7-2 Service Manual

Servicing PCIe Risers (CRU)
This section describes how to service PCIe risers. PCIe risers are customer-replaceable units
(CRUs) that require you to power off the server. For more information about CRUs, see
“Illustrated Parts Breakdown” on page 19 and “Customer-Replaceable Units” on page 21.
PCIe cards in all slots are installed on vertical risers. You must remove the associated riser to
remove and replace a PCIe card. You must remove all three PCIe risers when replacing the
motherboard.
Caution - These procedures require that you handle components that are sensitive to
electrostatic discharge. This sensitivity can cause the components to fail. To avoid
damage, ensure that you follow antistatic practices as described in “Electrostatic Discharge
Safety” on page 50.
Caution - Ensure that all power is removed from the server before removing or installing PCIe
risers, or damage to the PCIe cards installed in the risers might occur. You must disconnect all
power cables from the system before performing these procedures.
