Remove the crossbar

Follow the instructions in this section to remove the crossbar.

Attention

• Read Installation Guidelines and Safety inspection checklist 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.

• 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.

• If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top covers, or remove the server from the rack. See Remove the server from rails.

Note

The illustrations show how to remove a crossbar from a chassis with half-length PCIe risers. The removal procedure is similar for full-length PCIe risers.

Procedure

1. Make preparation for the task.
   1. Remove the front top cover. See Remove the front top cover.
   2. Remove the rear top cover. See Remove the rear top cover.
2. Disconnect all external cables from the PCIe adapters.
3. Disengage PCIe riser 1 from the crossbar.
   Figure 2. Disengaging PCIe riser

   
   
   
   1. Slightly lift the PCIe riser out of the chassis.
   2. Lift the kickstand(s) outward.
   3. Place the PCIe riser on top of the kickstand(s).
4. Repeat 3 to disengage the other two PCIe risers.
5. Remove the crossbar.
