• Read “Installation Guidelines” on page 47 and “Safety inspection checklist” on page 48 to ensure that you
work safely.
• Power off the server and peripheral devices and disconnect the power cords and all external cables. See
“Power off the server” on page 62.
• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-
sensitive components in their static-protective packages until installation, and handling these devices with
an electrostatic-discharge wrist strap or other grounding system.
• Before you remove any component of a RAID array (drive, RAID card, etc.), back up all RAID configuration
information.
Procedure
Step 1. Make preparation for the task.
a. If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the
top cover, or remove the server from the rack. See
“Remove the server from rack” on page 63.
b. Remove the top cover. See
“Remove the top cover” on page 277.
c. If there is any PCIe adapter installed on the riser card, record the cable connections first. Then,
disconnect all cables from the PCIe adapter.
Step 2. Remove the riser assembly.
• Riser 1 assembly (same for riser 2 assembly)
Note: The following uses the 3-slot riser cage as an example for illustration. The replacement
procedure for the 1-slot riser cage is similar.
Figure 201. Removing the riser 1 assembly
a. Loosen the screw that secures the riser assembly.
