Testing the cable management arms

1. From the front of the rack, lift the black tabs on the expansion enclosure and slowly pull the expansion enclosure from the rack to ensure that proper slack has been provided for the cables.
2. Ensure that the stops on the rails engage into the service position when the top access door is clear.
3. If you feel resistence, stop pulling and adjust any tight cables so that pulling the expansion enclosure from the rack does not strain any cables or pull them from the ports.
4. Ensure that you can remove the expansion enclosure from the rack until it is in the service position. The expansion enclosure is in the service position when it clicks into place and will not move any further.
5. Once you have finished adjusting the cables, pull the orange tabs on the side of the expansion enclosure, and push the expansion enclosure back into the rack until it locks into place.
6. Inspect the cables again to make any necessary final adjustments.
7. Using a Philips screwdriver, tighten the chassis-securing screws located under the self-locking latches on the front of the expansion enclosure. These screws secure the expansion enclosure chassis to the cabinet rails in the event that the cabinet needs to be moved.
