c. Using two hands, grasping each side of the replacement Controller Node, and align it with the
grooves in the slot.
d. Partially install the Controller Node into the slot by sliding it into the slot until it halts against the
insertion mechanism that is inside of the slot. Do not fully insert the Controller Node in the slot
at this time, because the cables must be reconnected before it is fully seated.
15. Reconnect the cables to the Controller Node.
While the Controller Node is still only partially inserted in the slot, reconnect the cables to the
Controller Node.
IMPORTANT:
Before fully seating the Controller Node, confirm that the network Ethernet cable is
connected to the MGMT port, which is required for the automatic Node-to-Node rescue.
16. Align and fully seat the Controller Node into the enclosure.
Push the gray Controller Node Rod into the replacement Controller Node.
If the UID LED is flashing blue after two minutes, this LED status indicates that the replacement
Controller Node is not properly seated, so repeat this step.
Once inserted, the replacement Controller Node powers up and goes through the automatic Node-to-
Node rescue before joining the cluster. This process might take up to 10 minutes.
IMPORTANT:
If the automatic Node-to-Node Rescue does not start automatically, contact your authorized
service provider.
