3.4.1 Mounting the SPARC M10-4S in a rack


3.4.1 Mounting the SPARC M10-4S in a rack
  1. Confirm that the rack mount kit supplied with the SPARC M10-4S is complete.
Note - The rack mount kit contains two types of cable support: Type-1 and Type-2. The Type-2 cable support is an integrated unit consisting of the parts indicated by numbers 2 to 5 in Figure 3-25. Steps 7 and 11 in the mounting procedure vary depending on the shape of the cable support. Attach the support according to the corresponding steps.

  1. Confirm that the rack is secured in place to prevent the rack from toppling over.
    For details, see "3.3.2 Securing the rack."
  2. Confirm the chassis mounting location in the rack. If necessary, mark the location on the supporting columns.
    The mounting locations have been predetermined for the building block configurations. See Figure 2-3 in "2.4.1 Mounting conditions for general racks."
  3. Step 4 differs depending on the shape of the supporting column holes of the rack. Perform the work appropriate to the shape of the supporting column holes of the rack.

  1. For racks with supporting columns having square holes
  1. Attach cage nuts to the left and right supporting columns of the rack.
    - Attachment locations in the front supporting columns: (From the bottom) 1U center, 2U bottom, and 3U top

    - Attachment locations in the rear supporting columns: (From the bottom) 1U center and 2U center

  1. a. Attach cage nuts from the inside of the rack.
    Orient the hooks of the cage nut vertically.
    Hook the hook at one end of a cage nut into a cage nut attachment hole of the rack.
    Figure 3-28 shows a cage nut hooked on the lower part of a hole.

  1. For supporting columns with M6 screw holes
  1. Remove the pins at the front and rear of the rail.
    a. Remove the screw (A in Figure 3-31) securing the rail pin.

    b. Remove the pin (B in Figure 3-31).

    c. Remove pins from the left and right rails in the same manner.

    d. Store the removed pins and screws (eight pins and eight screws in total) for future use when the chassis is moved.

  1. Attach the rail to the rack.
    Attach the rail such that the spring-loaded side (B in Figure 3-32) faces the front and the flange (C in Figure 3-32) faces the bottom.
    a. From the front of the rack, insert the rail protrusions into 2U top and 1U top in the front supporting column of the rack.

    b. Pull out the rail to as far as the depth of the rack.

    c. Insert the rail protrusions into 2U top and 1U bottom in the rear supporting column of the rack.

    d. Secure the rail with one M6 screw to the front supporting column of the rack. The fixing location is 2U bottom.

    e. Attach the other rail in the same manner.
Note - After removing its screw, hold the rail level with both hands. If the rail tilts, it may stretch.

  1. Attach the cable support fixing brackets to the rear supporting columns of the rack.
  1. For the Type-1 cable support
    a. Orient the notches (B in Figure 3-35) on the cable support fixing brackets (A in Figure 3-35) face down.

    b. From the rear of the rack, secure the rails and cable support brackets with two M6 screws to the rear supporting columns of the rack.

    The fixing locations are 1U center and 2U center.
    c. After attaching the cable support bracket, confirm that the rack door can close.
Note - If the door cannot close because the cable support fixing bracket or the cable support protrudes from the rear of the rack, do not attach the cable support bracket. However, secure the rail to the rack with two M6 screws.

  1. d. After attaching the cable support fixing brackets, confirm that the rack door can close.
Note - If the door cannot close because the cable support fixing bracket or the cable support protrudes from the rear of the rack, do not attach the cable support bracket. However, secure the rail to the rack with two M6 screws.
  1. Secure the rail sides by using the screws (M5) removed in step 5 (A in Figure 3-41).

  1. Mount the chassis in the rack.
    Mount the chassis from the front of the rack.
Note - The SPARC M10-4S weighs 60 kg. Mount the chassis in the rack with four or more people working together. Alternatively, use a lifter such as a hydraulic or mechanical jack.
  1. a. When using a lifter, secure it horizontally.

    b. Lift the chassis to the mounting location with the lifter or with human force.

    c. Put the rear part of the chassis on the flanges of the rails.

    d. Slide the chassis into the rack. At this time, store the handle on the side of the chassis. Also, confirm that the guide pins of the chassis (A in Figure 3-42) fit into their rail guides (B in Figure 3-42).

    e. Insert the chassis all the way to store it inside the rack.
Figure 3-42  Mounting in the rack
Figure 3-42  Mounting in the rack
  1. Secure the chassis to the rack.
    a. Push out the left and right slide locks on the front cover (C in Figure 3-42) to release the locks, and remove the front cover.

    b. Tighten the four M6 screws at four locations on the front of the chassis (A in Figure 3-43) to secure it to the rack.

    c. Insert the left and right hooks on the inside of the bottom of the front cover into the grooves at the bottom front of the chassis to attach the front cover.
Note - A label with the serial number of the chassis is affixed to the front cover. Be sure to attach the front cover to the corresponding chassis.

  1. Attach the cable support.
  1. For the Type-1 cable support
    a. From the inside of the cable support fixing bracket, align the two screws in the right cable support bracket with the circular holes at the front of the groove, and attach the screws (A in Figure 3-44).

    b. Slide the cable support bracket toward the chassis while holding the latch (B in Figure 3-44) attached to it.

    c. Attach the left cable support bracket in the same manner.
    At this time, the left and right sides should have been slid the same amount (depth) toward the chassis.

    d. Secure the cable support with two M3 screws (C in Figure 3-45).

    e. Close the rear door of the rack, and confirm that the cable support does not interfere. If it interferes, slide the cable support toward the chassis while holding the latches (B in Figure 3-44) of the left and right cable support brackets. The cable support should be in the position nearest the chassis, with the cable support bracket latches engaged.

    f. If the cable support interferes with the door even when you slide it toward the chassis as far as possible, remove the cable support.

  1. For the Type-2 cable support
    a. Tilt the cable support to align the circular holes at the rear of the groove with the two screws of a cable support fixing bracket (D in Figure 3-46), and attach it. Level the cable support. Then, align the circular holes at the other side with the two screws, and attach it.

Figure 3-47  Attaching the cable support (2)
Note - If the dimension between the front and rear columns of the rack is less than 740 mm, secure the cable support without sliding it in all the way. The fixing location varies depending on the dimension between the front and rear columns of the rack. Based on Figure 3-48, align the scale marks (E in Figure 3-48) (spacing: 10 mm) on the cable support with the screws (F in Figure 3-48) of the fixing brackets to secure the cable support.

Note - If you have difficulty laying a thick cable into the cable support, move forward the fixing location of the cable support to make the work easier.
  1. c. Close the rear door of the rack, and confirm that the cable support does not interfere. If the cable support interferes with the rear door, remove the cable support. Even if you remove the cable support, leave the rails secured with the two M6 screws to the rack.
  1. Detach the hook-and-loop fastener strips on the cable support.
    The detached hook-and-loop fastener strips are the four (A in Figure 3-49) on the right side as viewed from the rear of the chassis.
