Installing Boards and Subcards

Installing Boards and Subcards

  • Ensure that no water is on the device or board before inserting the board into the device.
  • Before you install boards, wear a grounding ESD wrist strap or ESD gloves to prevent electrostatic discharge on the human body from damaging sensitive components.
  • Empty slots must be filled with filler panels.
  • Boards must be installed upside down in the lower board cage of the NE40E-X16A.
  • If a board cannot be inserted into a slot, check whether the color on both ends of the board panel is the same as the color on the slot. If not, the board is being inserted into an incorrect slot.
  • Before installing a subcard, remove unnecessary guide rails from the board and store them properly.

Slot Layout

Interface Numbering

An interface is numbered in the format of slot number/subcard number/port number.

  • Slot number: Slots for LPUs are numbered 1 to 16 from top to bottom and from left to right.
  • Subcard number: Subcards on LPUs are numbered starting with 0. If there is no subcard on an LPU, the subcard number is 0.
  • Port number: Ports are numbered starting with 0.

Removing redundant guide rails

To install a half-width or a full-width subcard on a motherboard, remove unnecessary guide rails first.

  1. Use a Phillips screwdriver to remove the screws.
  2. Remove the guide rails from the board.

Installing Boards and Subcards

Installing boards, as shown in A in Figure 8-19

  1. Remove the filler panel from the slot.
  2. Slide the board along the guide rails into the slot.
  3. Grasp both ejector levers and pivot them inward to secure the board.
  4. Use the Phillips screwdriver to tighten the captive screws.

Installing subcards, as shown in B in Figure 8-19

  1. Insert a subcard along the guide rails into the slot on the board.
  2. Use the Phillips screwdriver to tighten the captive screws.

Installing SFUs

NOTE:
  • Before installing an SFU, ensure that ejector levers are available for use. Installing SFUs without ejector levers may cause the boards to fail to be powered on and registered.
  • After installing an SFU, remove the ejector levers from the SFU and attach them on the cabinet or chassis for future use.
Figure 8-20 Ejector levers for installing SFUs

  • Do not use ejector levers to lift a board.
  • Use both ejector levers when pushing or pulling a board. Never use only one.
  1. Obtain the ejector levers from the both sides of the chassis.

  2. Slide an SFU along the guide rails halfway into the slot. Push the board into half of the board along the guide rails.

  3. Press down the buckle on the ejector levers and insert them into ejector lever connectors on the SFU.

  4. Use both hands to open the two ejector levers of the SFU, and push the SFU into the slot along the guide rails until the two ejector levers of the SFU are connected to the edge of the chassis.

  5. Grasp the ejector levers and simultaneously pivot them inward to secure the SFU in the slot.

  6. Press down the elastomer fasteners on the ejector levers and remove them from the SFU.

  7. Put the ejector levers back to their original positions.
