Attaching the cable chains

The final step in installing a drive drawer is attaching the left and right cable chains to the drive tray. 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 bracket in the enclosure before inserting the chain's vertical connector into the vertical bracket in the enclosure.

Before you begin

Steps

  1. From the back of the drive tray, remove the fan canister on the left side, and set it aside.
  2. If the tray is powered on, ensure that the right fan goes to its maximum speed.
    CAUTION:
    Possible equipment damage due to overheating – If the tray is powered on, do not remove both fans at the same time. Otherwise, the equipment might overheat.
  3. Follow these steps to attach the left cable chain:
    1. Locate the horizontal and vertical connectors on the left cable chain and the corresponding horizontal and vertical brackets inside the enclosure.
    2. Align both cable chain connectors with their corresponding brackets.
    3. Slide the cable chain's horizontal connector under the guide rail on the horizontal bracket, and push it in as far as it can go.
      CAUTION:
      Risk of equipment malfunction — Make sure to slide the connector underneath the guide rail on the bracket (shown in the figure on the left). If the connector rests on the top of the guide rail (shown in the figure on the right), problems might occur when the system runs.

    4. Slide the vertical connector on the left cable chain into the vertical bracket.
      If the power is on, the drives automatically spin up as soon as the first cable chain is connected.
    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 left fan canister. If the drive tray is receiving power, confirm that the green LED on the back of the fan is now on and that air is now coming out of the back.
  5. From the back of the drive tray, remove the fan canister on the right side of the tray.
  6. If the tray is powered on, ensure that the left fan goes to its maximum speed.

    4. Slide the vertical connector on the right cable chain into the vertical bracket.
    5. Once 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.
  8. Reinstall the right fan canister. If the drive tray is receiving power, confirm that the green LED on the back of the fan is now on and that air is now coming out of the back.
  9. If the power to the drive tray is off, reapply power, as follows:
