Procedure
1. From the back of the drive shelf, remove the fan canister on the right side, and set it aside.
2. If the shelf is powered on, ensure that the left fan goes to its maximum speed.
Attention: Possible equipment damage due to overheating – If the shelf is powered on, do not
remove both fans at the same time. Otherwise, the equipment might overheat.
3. Attach the right cable chain:
a) Locate the horizontal and vertical connectors on the right cable chain and the corresponding horizontal
guide rail and vertical guide rail inside the enclosure.
b) Align both cable chain connectors with their corresponding guide rails.
c) Slide the cable chain's horizontal connector onto the horizontal guide rail, and push it in as far as it can
go.
Attention: Risk of equipment malfunction — Make sure to slide the connector into the guide
rail. If the connector rests on the top of the guide rail, problems might occur when the system
runs.
The figure shows the horizontal and vertical guide rails for the second drive drawer in the enclosure.
