Each
Replication Engine contains three PCI-express (PCIe) risers that are located side by side at the back of the
Replication Engine. The three risers, though similar, are not interchangeable. Each riser hosts two PCIe3 slots and can accommodate two PCIe3 host bus adapters (HBAs). The risers are field replaceable units (FRUs). Replacing a riser assembly requires you to bring the
Replication Engine offline. The following figure shows the location of the three risers.
Note: By design, the risers are mechanically dependent upon each other. Even if there are no PCIe3 HBAs installed, all risers must be installed.

Note: The risers can be accessed only after removing the top cover over the Replication Engine chassis.
Note: To replace a riser, you do not need to remove the Replication Engine from the rack but extend it along the Replication Engine rails using the cable management arm (CMA).
Note: Ensure that all power is removed from the Replication Engine before replacing the riser. Disconnect the power cords before performing the riser replacement procedure.
