Install the compute node cover

Use this procedure to install the compute node cover.

Before installing the compute node cover:
  1. Read Installation Guidelines to ensure that you work safely.

  2. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.
You cannot insert the compute node into the Lenovo Flex System chassis until the cover is installed and closed. Do not attempt to override this protection.
shock hazard
Hazardous voltage, current, and energy levels might be present. Only a qualified service technician is authorized to remove the covers where the label is attached.
Statement 21
Shock hazard
Hazardous energy is present when the compute node is connected to the power source. Always replace the compute node cover before installing the compute node.
240VA shock hazard

Hazardous energy present. Voltages with hazardous energy might cause heating when shorted with metal, which might result in spattered metal, burns, or both.

  1. Orient the cover so that the posts on the inside of the cover slide into the slots on the compute node.
    Before you close the cover, make sure that the air baffle and all components are installed and seated correctly and that you have not left loose tools or parts inside the compute node. Retention clips that secure the I/O expansion adapters must be in the closed position to install the cover.

  2. Hold the front of the compute node and slide the cover forward to the closed position, until it clicks into place.
After you install the compute node cover, complete the following steps:
  1. Install the compute node into the chassis (see Install the compute node in the chassis ).

  2. Power on the compute node.
