Attach cable chains

You must attach the cable chains so you can safely re-install the drives in the drive drawer.

Before you begin

About this task

When attaching a cable chain, reverse the order you used when disconnecting the cable chain. You must insert the chain's horizontal connector into the horizontal guide rail in the enclosure before inserting the chain's vertical connector into the vertical guide rail in the enclosure.

Steps

  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:
    1. Locate the horizontal and vertical connectors on the right cable chain and the corresponding horizontal guide rail and vertical guide rail inside the enclosure.
    2. Align both cable chain connectors with their corresponding guide rails.
    3. 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.

    4. Slide the vertical connector on the right cable chain into the vertical guide rail.
    5. After you have reconnected both ends of the cable chain, carefully pull on the cable chain to verify that both connectors are latched.
      Attention: Risk of equipment malfunction — If the connectors are not latched, the cable chain might come loose during drawer operation.
  4. Reinstall the right fan canister. If the drive shelf is receiving power, confirm that the amber LED on the back of the fan is now off and that air is now coming out of the back.
    The LED could remain on for as long as a minute after you reinstall the fan while the fan settles into the correct speed.

    3. Slide the cable chain's horizontal connector into the horizontal guide rail and push it in as far as it will go.
      Attention: Risk of equipment malfunction — Make sure to slide the connector within the guide rail. If the connector rests on the top of the guide rail, problems might occur when the system runs.
    4. Slide the vertical connector on the left cable chain into the vertical guide rail.
    5. After you reconnect both ends of the cable chain, carefully pull on the cable chain to verify that both connectors are latched.
      Attention: Risk of equipment malfunction — If the connectors are not latched, the cable chain might come loose during drawer operation.
