Removing and Installing PTX10000 Switch Fabric Components

 

Each PTX10008 or a PTX10016 router contains six SIBs that are installed vertically, mid-chassis, between the line cards and the routing and control boards in the front and the fan trays in the rear. To install or remove the switch interface boards in a PTX10008 router or a PTX10016 router, refer to the following sections:

Handling and Storing PTX10000 Line Cards, Routing and Control Boards, and SIBs

The PTX10008 and PTX10016 chassis have several field-replaceable units (FRUs) that have fragile components. To avoid damaging the line cards, Routing and Control Boards (RCBs), and Switch Interface Boards (SIBs), be sure you follow the following safe handling practices. This topic covers:

Holding Line Cards and Control Boards

Pay proper attention to the way you are holding line cards and RCBs. Line cards and RCBs are installed horizontally and it is best to hold them by the sides of the units when they are not in the chassis.

When walking with a line card or RCB:

  1. Orient the line card or the RCB so that the faceplate is toward you.
  2. Grasp each side of the unit firmly as you slide the unit out of the chassis.
  3. Take care not to strike the unit against any object as you carry it.Caution

    Never hold the line card or RCB by the connector edge. The connectors are fragile and the line card or RCB will not seat properly if the connector is damaged. See Figure 1.

  4. If you must rest a line card or control board on an edge, place a cushion between the edge and the surface.Caution

    Do not stack line cards or RCBs on top of one another or on top of any other component.

  5. Place each line card separately in an electrostatic bag or on an antistatic mat placed on a flat, stable surface.

Holding SIBs

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 electrostatic bag for storage. See Figure 2.

Figure 2: PTX10000 SIB

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 will not align and seat properly if the connector is damaged.

    Caution

    Do not stack SIBs on top of one another or on top of any other component.

Storing Line Cards, Routing and Control Boards, and SIBs

You must store line cards, Routing and Control Boards, and 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 electrotatic bags are fragile, inserting the line card into the bag is best done with two people.

To insert a line card, RCB, or SIB into an electrostatic 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 line card, RCB, or 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.

Installing a PTX10000 Switch Interface Board

A PTX10008 and a PTX10016 router has 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 install a SIB. See Removing a PTX10000 Fan Tray.

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

  • Electrostatic bag or antistatic mat

  • Electrostatic discharge (ESD) grounding strap

To install a SIB:

  1. Place an electrostatic bag or an antistatic mat on a flat, stable surface.
  2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis. There is an ESD point located next to the protective earthing terminal and below PSU 5 on the PTX10008 rear panel (see Figure 3) and below PSU_9 on the PTX10016 rear panel (see Figure 4).

  3. Remove the appropriate fan tray (see Removing a PTX10000 Fan Tray).
  4. Either remove the failing SIB (see Removing a PTX10000 Switch Interface Board) or remove the cover panel by grasping each side of the plate and pulling straight out (see Figure 5 for an example using the PTX10008).
    Figure 5: Removing a SIB Cover Plate on a PTX10008

  5. Lift the SIB by the handle with one hand and support the lower edge with the other hand.
  6. Holding the SIB vertically, slide the SIB into the open slot until the ejector handles engage and start to close.
  7. Grasp the two ejector handles and fold them inward until they latch to seat the SIB (see Figure 6 for the PTX10008 and Figure 7 for the PTX10016).

  8. Hand-tighten the captive screws.
  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 in order 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.

Removing a PTX10000 Switch Interface Board

A PTX10008 and a PTX10016 router has 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 Removing a PTX10000 Fan Tray.

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

  • Electrostatic bag or antistatic mat

  • Electrostatic discharge (ESD) grounding strap

To remove a SIB (see Figure 11):

  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 packets do not flow through the SIB, power down the SIB instead of taking the SIB offline. To power down the SIB, use the set chassis sib power-off slot slot number command. To bring up a new SIB up in the slot, you must delete the old configuration using the delete chassis sib power-off slot slot number command.

  2. Place an electrostatic bag or an antistatic mat on a flat, stable surface.
  3. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis. There is an ESD point located next to the protective earthing terminal and below PSU 5 on the PTX10008 rear panel (see Figure 8) and below PSU_9 on the PTX10016 (see Figure 9.

  4. Remove the appropriate fan tray (see Removing a PTX10000 Fan Tray).
  5. Loosen the captive screws at the top and bottom of the card.
  6. Grasp both ejector handles and spread them apart. The SIB slides about a quarter of the way out of the slot. See Figure 10.

  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 (see Figure 11 and Figure 12).

  8. Support the SIB as you rotate the SIB 90 degrees and place it on the antistatic mat with the printed circuit (PC) board facing upward. Be careful not to bump or handle the SIB by the connectors. If you do not have an antistatic mat, have another person help you slide the electrostatic bag over the SIB before placing it on the stable surface. See Figure 13.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.
