Riser board assemblies include printed circuit boards and PCIe slots in which HBAs can be inserted based on system type and configuration. A failed riser board assembly can cause read and write errors because the HBAs will not be able to function properly. Replace a failed riser board as soon as possible.
- Prerequisites:
Before handling a component, touch a grounded surface to discharge any static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand on an ESD mat while replacing components.
Ensure that you have a Phillips Number 2 screwdriver with at least a 4-inch shaft.
Fail over the Pilot before replacing the component using Guided Maintenance.
Note: The Pilot must be failed over to prevent data loss or data corruption during the component replacement process.
Each Pilot contains three riser board assemblies (R1 to R3 – left to right) located side-by-side at the back of the Pilot next to the power supplies. Risers are customer replaceable units (CRUs). The SAS HBA is the only HBA that is inserted into the Pilot riser. Replacing a riser requires you to power off the Pilot. The following figure shows the location of the riser board assemblies on the Pilot motherboard.

Note: The risers can be accessed only after removing the cover over the Pilot chassis.
Important! Disconnect any cables connected to the HBAs in the riser that must be replaced.
Note: To replace a riser, you do not need to remove the Pilot from the rack but extend the Pilot along the Pilot rails using the cable management arm (CMA).
