About this task
Attention: 
•  Read 
“Installation Guidelines” on page 55 and “Safety inspection checklist” on page 56 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 73.
•  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.

Procedure
Step 1.  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 73.
Step 2.  If the server is installed with the security bezel, remove it first. See 
“Remove the security bezel” on 
page 237
.
Step 3.  Disconnect the VGA cable, the front-I/O-module cable, or both cables from the system board 
assembly. 
Notes: 
•  If you need to disconnect cables from the system board assembly, disengage all latches or 
release tabs on cable connectors first. Failing to release the tab before removing the cables will 
damage the cable sockets on the system board assembly. Any damage to the cable sockets 
might require replacing the system board assembly.
•  The connectors on your system board assembly might look different from those in the 
illustration, but the removal procedure is the same.
1.  Press the release tab to release the connector.
2.  Disengage the connector from the cable socket.
