Installing Bays

Precautions

• Storage devices are debugged before delivery. If multiple sets of storage devices are delivered, ensure that each set is installed in the correct system and that devices are not mixed up.
• If a storage system uses multiple controller enclosures, install storage devices according to the following principles:
  • Controller enclosure: On top of the controller enclosure you can find its ID, which indicates the bay the controller enclosure belongs to. If the controller enclosure ID is CTE0, the controller enclosure belongs to system bay 0. CTE represents a controller in a system bay, CTE0 represents a controller in system bay 0, CTE1 a controller in system bay 1, and so on.
  • Disk enclosure: A disk enclosure ID is labeled on a disk enclosure's expansion modules. It indicates which controller enclosure manages the disk enclosure. In DAEXYZ-M, DAE indicates a disk enclosure, X the system bay ID, Y the disk enclosure loop ID, Z the enclosure ID in the disk enclosure loop, and M the disk enclosure's expansion module. For example, DAE000–B indicates expansion module B in disk enclosure 0, which is in disk enclosure loop 0 of system bay 0. Configure disk enclosures based on these configuration principles (this does not include disk enclosures with configuration disks).
• Upon arrival, devices are identified by their packing list number (P/L No.) shown on the outer carton. The P/L No. is the same for devices in the same set.
  • The packing list count (Site Count) indicates the number and ID of the devices.

  Before unpacking goods, identify different sets of storage devices and store them separately to prevent device mix-up from causing a system failure.

  Figure 3-48 shows the P/L No. and Site Count on the outer carton.

  Figure 3-48 P/L No. and Site Count on the outer carton
  
  • The system bay (SMB) label helps identify the number of system bays in a set of devices.

    The SMB label is attached close to the buckle at the upper left corner of the outer carton plate, as shown in Figure 3-49. SMB0 indicates system bay 0.

    Figure 3-49 Position of the SMB label on the outer carton
    

• After unpacking the carton, you can identify different sets of devices by using the order number on the qualification card on the rear of the bay's top panel. The order numbers of the same set of devices are the same.
  • Figure 3-50 and Figure 3-51 show the position of the qualification card and the order number on the qualification card.

  • The SMB label helps identify the number of system bays in a set of devices.

  The SMB label is attached to the upper left corner of the rear door of the system bay, as shown in Figure 3-52. SMB0 indicates system bay 0.

Prerequisites

• The SMB ID of the system bay to be installed must be different from that of an existing one. Otherwise, capacity expansion will fail.

Before the installation, check the SMB ID of the system bay to be installed in the upper left corner of the rear door. If the SMB ID of the system bay to be installed is the same as that of an existing one, use another system bay for installation. If no other system bay is available, contact technical support engineers.

• An installation position has been planned for each bay. Figure 3-53 shows the bay base dimensions.

Procedure

1. Use a wrench to move leveling feet to the highest position, as shown in Figure 3-54.
   Figure 3-54 Moving leveling feet to the highest position
   

   When leveling feet are in the highest position, the maximum climbing angle of a bay is 10 degrees, as shown in Figure 3-55.

   Figure 3-55 Maximum climbing angle of a bay
   
   • Do not push a bay from a flat surface to a slope greater than 10 degrees. Otherwise, leveling feet get scratches, or even the bay falls down.
   • If a bay cannot be moved to the customer's equipment room because stairs exist, doors are not high enough, the bearing capacity of floors is insufficient, or there is a slope greater than 10 degrees along the passageway, follow instructions in the Disassembling and Reinstallation Guide to move the bay to the designated location.

2. (Optional) Route network cables and optical fibers of system bays and disk bays from sides or on the top of the bays. You can also route them underfloor if there are cabling holes in the floor.
   • Routing cables from cable holes on the two sides of a bay

     Perform this procedure only when your storage system is configured with system bays and disk bays. In this case, there is one system bay and one disk bay placed beside each other. You need to remove the system bay side panel against the disk bay and the disk bay side panel against the system bay before installation so that cables can be routed between the two bays, as shown in Figure 3-56. If there is no disk bay, skip this step.

   Figure 3-56 Routing cables from cable holes on the two sides of a bay
   
   1. Insert the key delivered with the bay to any of the two keyholes on the side panel and turn the key clockwise to open the lock, and then do the same for the other keyhole, as instructed in step 1 in Figure 3-57.
      Figure 3-57 Removing side panels
      

      Locks on the front and rear doors and the side panels use the same key.

   2. Pull the handle below the keyhole to detach the side panel's upper part from the bay, as instructed in step 2 in Figure 3-57.
   3. Remove the side panel from the bay, as instructed in step 3 in Figure 3-57.
   • Routing cables on the top of the bay, as shown in Figure 3-58.
   Figure 3-58 Routing cables on the top of a bay
   

3. Move the bay to the planned position.
4. Use a wrench to move leveling feet down until the wheels can rotate horizontally without touching the ground, as shown in Figure 3-59.
   Figure 3-59 Moving leveling feet down
   

5. (Optional) Connect adjacent bays using connecting plates.
   1. Open the front and rear doors of the bays.
   2. Install connecting plates.
      • Use two connecting plates between each two adjacent bays (one on the front side of the two bays and one on the rear side).
      • Connecting plates are delivered with bays and can be found at the bay bottom near the rear door.

      There are two recesses at the junctions between a bay and its doors, as shown in Figure 3-60. Move a connecting plate through a recess, and then use screws to fix one end of the connecting plate onto a bay and the other end onto the adjacent bay. Perform the same operations to install other connecting plates.

   3. Close the front and rear doors of the combined bays.

      Gently press the door plate, rotate the door handle clockwise, and spin down the door handle vertically to lock the door, as shown in Figure 3-61.

   If any problem occurs when locking the door, do not forcibly lock the door. Contact Huawei technical support.
