Steps
1. Rotate the power cable retention bail to the left (right for top power supply). Disconnect the power cable from the power
supply.
The following illustration shows an AC power supply.
Figure 77. Removing the power cable
2. Disconnect the network and all other cables from the back of the I/O modules and network ports on the node.
NOTE: Label the cables before you remove them.
NOTE: Do not remove any cables from the other node.
3. Remove the node labels from the node handles.
4. Pull the orange release trigger while gently pushing in on the node.
The hook disengages from the locking mechanism, and the release tab slides out.
NOTE: The node comes completely out of the chassis. Be prepared to support the node to avoid dropping it.
NOTE: The release trigger and handle for node B is on the top left. The release trigger and handle for node A is on the
bottom right.
CAUTION: Removing the incorrect node will lead to loss of system power and cached data will be lost.
