Removing the upper compute node

Use this information to separate the upper and lower compute nodes of the Flex System x222 Compute Node.

Before you remove the upper compute node, complete the following steps:
  1. Read Safety and Installation guidelines.
  2. If the Flex System x222 Compute Node is installed in a chassis, remove it (see Removing a compute node from a chassis for instructions).
  3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward the left.
  4. Remove any USB devices or console breakout cables that are connected to the upper or lower compute nodes.
Attention
Make sure that all devices plugged in to the front of the Flex System x222 Compute Node have been removed before opening the upper compute node.

CAUTION
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.
Note
  • The upper compute node acts as the cover for the Flex System x222 Compute Node. You can not install the Flex System x222 Compute Node in a chassis unless the upper compute node is installed.
  • Although the upper and lower compute nodes are configured and operated independently, they must be installed together as a complete Flex System x222 Compute Node unit.

To remove the upper compute node, complete the following steps:

  1. Locate the release lever at the rear of the compute node.
  2. Slide the release latch and rotate the release lever to open it.
    Attention
    Make sure that all devices connected to the front of the Flex System x222 Compute Node are removed before opening the upper compute node.
  3. Lift up on the rear edge of the upper compute node and rotate it open until it is nearly vertical (open between 70-degrees and 80-degrees).
    Attention
    Rotating the upper compute node open past 90-degrees can cause it to slip from the pins on the lower compute node.
  4. Lift the upper compute node away from the lower compute node.
