A deployment engineer is installing a PowerEdge XE8640 server. The server is on a lift, and they have aligned the server inner rails with the rail assemble that are secured in the rack. The engineer
can only push the server into the rack a short distance before it stops. Pushing forcefully causes the rack to slide back.
What action should the deployment engineer take?
Understanding Rail Locks:
The PowerEdge XE8640 server rails are equipped with a locking mechanism to secure the server during transport and installation. This prevents the server from moving unintentionally and ensures stability.
Identifying the Issue:
When the server stops after being pushed only a short distance into the rack, it is likely due to the rail lock engaging. This lock must be released to allow the server to slide fully into place.
Releasing the Rail Lock:
Locate the rail lock mechanism on the rails. This is typically a lever or button that, when pressed, releases the lock, allowing the server to slide further into the rack.
Detailed Steps:
Align the Server: Ensure that the server is properly aligned with the rails before proceeding. Misalignment can cause the server to get stuck or make it difficult to release the lock.
Press the Release Mechanism: With the server partially inserted, locate and press the release mechanism on both sides of the rails. This should disengage the locks.
Slide the Server: Once the locks are released, carefully push the server into the rack until it is fully seated. Ensure that the server is evenly aligned to avoid binding or getting stuck.
Avoiding Forceful Methods:
Avoid using excessive force to push the server into the rack as it can cause damage to the server, rails, or rack. Additionally, pushing forcefully without releasing the rail lock can lead to misalignment and potential hardware issues.
Safety and Assistance:
Ensure the lift is stable and properly aligned with the rack to prevent movement. If needed, have an assistant stabilize the lift while performing the installation steps.
