Install and Remove PTX10004 Switch Fabric Components

Each PTX10004 router contains a minimum of three and a maximum of six Switch Interface Boards (SIBs) that are installed vertically, mid-chassis, between the line cards and the Routing and Control Boards (RCBs) in the front and the fan trays in the rear. To install or remove the switch interface boards in a the router, read the following sections.

How to Handle and Store PTX10004 SIBs

The PTX10004 SIBs have fragile components. To avoid damage to the SIBs, be sure you follow safe handling practices.

How to Hold a SIB

SIBs are installed vertically and should be held vertically until they are clear of the router before rotating them 90 degrees and placing them on an antistatic mat or placing them in an antistatic bag for storage. See Figure 1.

Figure 1: JNP10004-SF3 Switch Interface BoardJNP10004-SF3 Switch Interface Board

The proper method of holding a SIB is to:

  1. Hold the SIB by the ejectors while you keep the SIB vertical, and slide the SIB about three-quarters of the way out of the chassis.
  2. Place one hand underneath the SIB to support it, and slide it completely out of the chassis.
    CAUTION:

    Never hold the SIB by the connector edge. The connectors are fragile and the SIB won’t align and seat properly if the connector is damaged.

    CAUTION:

    Don’t stack SIBs on top of one another or on top of any other component.

How to Store a Switch Interface Board

You must store SIBs either in the chassis or in a spare shipping container, horizontally and sheet-metal side down. Do not stack these units on top of one another or on top of any other component. Place each unit separately in an antistatic bag or on an antistatic mat placed on a flat, stable surface.

Note:

Because these units are heavy and because antistatic bags are fragile, inserting the line card into the bag is best done by two people.

To insert a SIB into an antistatic bag:

  1. Hold the unit horizontally with the faceplate toward you.
  2. Slide the opening of the bag over the connector edge.

If you must insert the SIB into a bag by yourself:

  1. Lay the unit horizontally on an antistatic mat that is on a flat, stable surface with the sheet-metal side down.

  2. Orient the unit with the faceplate toward you.

  3. Carefully insert the connector edge into the opening of the bag and pull the bag toward you to cover the unit.

Install a PTX10004 Switch Interface Board

A PTX10004 router has up to six SIBs that are located in the middle of the chassis behind the fan trays. SIB 0 through SIB 2 are located behind the left fan tray, and SIB 3 through SIB 5 are located behind the right fan tray. You must remove the appropriate fan tray to install a SIB. See Remove a PTX10004 Fan Tray.

Ensure that you have the following equipment with you before you install a SIB:

  • Antistatic bag or antistatic mat

  • Electrostatic discharge (ESD) grounding strap

  • Phillips (+) number 2 screwdriver (optional)

To install a SIB:

  1. Place an antistatic bag or an antistatic mat on a flat, stable surface.
  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to an ESD point on the chassis. There is an ESD point located next to the protective earthing terminal and below the bottom power supply on the rear of the PTX10004 (see Figure 2).

  3. Remove the appropriate fan tray (see Remove a PTX10004 Fan Tray).
    CAUTION:

    Do not remove both fan trays at the same time. If you remove both fan trays, the system triggers a thermal alarm and shuts down the chassis.

  4. Either remove the failing SIB (see Remove a PTX10004 Switch Interface Board) or remove the cover by grasping each side of the plate and pulling straight out (see Figure 3).
    Figure 3: Remove a SIB Cover on a PTX10004Remove a SIB Cover on a PTX10004
  5. Lift the SIB by the handle with one hand and support the lower edge with the other hand.
  6. Hold the SIB vertically and slide the SIB into the open slot until the ejector handles engage and start to close.

    If you are installing multiple SIBs, such as during a hardware upgrade, install the SIBs from the lowest slot number 0 to the highest 5. Don’t skip slots.

  7. Grasp the two ejector handles and fold them inward until they latch to seat the SIB (see Figure 4).
    Figure 4: Install a PTX10004 Switch Interface BoardInstall a PTX10004 Switch Interface Board
  8. Tighten the captive screws using your thumb and forefinger or using a Phillips screwdriver until the captive screws are hand-tight.
  9. Bring the SIB online using the request chassis sib slot slot number online command.

    You can check the status of the SIB using the show chassis fabric sibs and the show chassis fabric plane-location commands. For example:

    Note:

    If you completely powered off the SIB using the set chassis sib power-off slot slot command, you must delete the configuration to bring the SIB online. To delete the configuration and bring a replacement SIB online, use the delete chassis sib power-off slot slot number command.

Remove a PTX10004 Switch Interface Board

A PTX10004 router has up to six Switch Interface Boards (SIBs) that are located in the middle of the chassis behind the fan trays. SIB 0 through SIB 2 are located behind the left fan tray and SIB 3 through SIB 5 are located behind the right fan tray. You must remove the appropriate fan tray to access the failing SIB. See Remove a PTX10004 Fan Tray.

Ensure you have the following equipment on hand before replacing a SIB:

  • Antistatic bag or antistatic mat

  • Electrostatic discharge (ESD) grounding strap

  • Phillips (+) number 2 screwdriver (optional)

To remove a SIB:

  1. Take the SIB offline using the request chassis sib slot slot number offline command.
    Note:

    If you suspect the SIB is faulty and want to ensure that packets do not flow through the SIB, power off the SIB instead of taking the SIB offline. To power down the SIB, use the set chassis sib power-off slot slot number command. Before you bring a new SIB in that slot online, you must delete the old configuration using the delete chassis sib power-off slot slot number command.

  2. Place an antistatic bag or an antistatic mat on a flat, stable surface.
  3. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to an ESD points on the chassis. There is an ESD point located next to the protective earthing terminal and below the bottom power supply on the rear of the PTX10004, (see Figure 5).

  4. Remove the appropriate fan tray (see Remove a PTX10004 Fan Tray).
    CAUTION:

    Do not remove both fan trays at the same time. If you remove both fan trays, the system triggers a thermal alarm and shuts down the chassis.

  5. Loosen the captive screws at the top and bottom of the SIB using your thumb and forefinger or a Phillips screwdriver. See Figure 6.

  6. Grasp both ejector handles and bring them together. The SIB slides about a quarter of the way out of the slot. See Figure 7.
    Figure 7: Join the Ejector HandlesJoin the Ejector Handles
  7. Grasp the ejector handle with one hand and place your other hand under the SIB for support as you slide the SIB out of the slot.
  8. Support the SIB as you rotate the SIB 90 degrees and place it on the antistatic mat with the printed circuit board (PCB) facing upward. Be careful not to bump or handle the SIB by the connectors. If you don’t have an antistatic mat, have another person help you slide the antistatic bag over the SIB before you place it on a stable surface. See Figure 8.
    CAUTION:

    Do not stack hardware components on top of one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.
