Maintain the PTX10016 Switch Fabric Components

The PTX10016 router contains Switch Interface Boards (SIBs). The SIBs 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 SIBs in a PTX10016 router, read the following sections.

How to Handle and Store PTX10016 Line Cards, RCBs, and SIBs

The PTX10016 chassis supports 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.

How to Hold Line Cards and RCBs

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

When walking with a line card or an 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 the RCB by the connector edge. The connectors are fragile and the line card or the RCB will not seat properly if the connector is damaged. See Figure 1.

  4. If you must rest a line card or an RCB 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 antistatic bag or on an antistatic mat placed on a flat, stable surface.

How to Hold Switch Interface Boards

Switch Interface Boards (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 2 for an example.

Figure 2: JNP10016-SF SIB for the PTX10016 Router JNP10016-SF SIB for the PTX10016 Router

The proper method of holding a SIB is to:

  1. Have one person hold the handle in the center of the SIB faceplate with one hand and the top of the SIB with the other hand while keeping the SIB vertical, and slide the SIB about three-quarters of the way out of the chassis.
  2. While the first person continues to hold the handle and top of the SIB, have another person 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.

How to Store Line Cards, RCBs, and SIBs

You must store line cards, RCBs, 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 antistatic 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 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 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.

Install a Switch Interface Board in the PTX10016 Router

A PTX10016 router has up to six Switch Interface Boards (SIBs) that are installed 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 Fan Tray from the PTX10016 Router.

Before you install a SIB, ensure that:

  • You have two antistatic bags or antistatic mats

  • The operators follow proper ESD procedures to avoid static discharge

To install a SIB:

  1. Place an antistatic bag or an antistatic mat on a flat, stable surface.
  2. Taking care not to touch the SIB components, pins, leads, or solder connections, remove the SIB from its bag and place it on the antistatic bag or the antistatic mat.
  3. Remove the appropriate fan tray (see Remove a Fan Tray from the PTX10016 Router) and place it in the antistatic bag or on the antistatic mat.
  4. If there is an SIB in the slot you want to install the SIB, remove it by following the steps in Remove a Switch Interface Board from the PTX10016 Router and place it on the antistatic bag or the antistatic mat. If the slot has a blank SIB cover panel in it, remove it by pulling the top lever down and pulling the bottom lever up simultaneously (see Figure 3).
    Figure 3: Remove a Blank SIB Cover Panel Remove a Blank SIB Cover Panel
  5. Have one person hold the handle in the center of the SIB faceplate with one hand and the top of the SIB with the other hand while keeping the SIB vertical. Have another person place one hand underneath the SIB and lift the SIB. See Chassis and Component Lifting Guidelines.
  6. CAUTION:

    Before you slide the SIB into the slot, ensure that the SIB is aligned correctly. Misalignment might cause the components, pins, leads, or solder connections to bend, making the SIB unusable.

     Holding the SIB vertically, slide the SIB into the open slot until the ejector handles engage and start to close. The connectors must face the chassis.
  7. Grasp the two ejector handles and fold them inward until they latch to seat the SIB (see Figure 4).
    Figure 4: Install a SIB in the PTX10016 Router Install a SIB in the PTX10016 Router
  8. Tighten the captive screws by using a screwdriver.
  9. Bring the SIB online by using the request chassis sib slot slot number online command.

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

    Note:

    If you completely powered off a failing SIB by using the set chassis sib power-off slot slot number command in a router with Junos OS installed or by using the set chassis sib slot slot number power-off command in a router with Junos OS Evolved installed, you must delete the configuration in order to bring the new SIB online. To delete the configuration and bring a replacement SIB online, use the delete chassis sib power-off slot slot number command in a router with Junos OS installed or by using the delete chassis sib slot slot number power-off command in a router with Junos OS Evolved installed.

Remove a Switch Interface Board from the PTX10016 Router

A PTX10016 router has up to six Switch Interface Boards (SIBs) that are installed 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 Fan Tray from the PTX10016 Router.

Ensure you have the following equipment with you before replacing a SIB:

  • Two antistatic bags or antistatic mats

  • The operators follow proper ESD procedures to avoid static discharge

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 off the SIB, use the set chassis sib power-off slot slot number command in a router with Junos OS installed or by using the set chassis sib slot slot number power-off command in a router with Junos OS Evolved installed. 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 in a router with Junos OS installed or by using the delete chassis sib slot slot number power-off command in a router with Junos OS Evolved installed.
  2. Place an antistatic bag or an antistatic mat on a flat, stable surface.
  3. Remove the appropriate fan tray (see Remove a Fan Tray from the PTX10016 Router) and keep it in the antistatic bag or on the antistatic mat.
  4. By using your fingers, loosen the captive screws at the top and bottom of the SIB.
  5. Grasp both ejector handles and spread them apart. The SIB slides about a quarter of the way out of the slot. See Figure 5.
    Figure 5: Loosen the Captive Screws and Spread the Ejector Handles Loosen the Captive Screws and Spread the Ejector Handles
  6. Hold the ejector handles and slide the SIB about three-quarters of the way out of the chassis while keeping the SIB vertical.
  7. Place one hand underneath the SIB to support it, and slide it completely out of the chassis (see Figure 6).
    Figure 6: Remove the SIB from the PTX10016 Router Remove the SIB from the PTX10016 Router
  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 do not have an antistatic mat, have another person help you slide the antistatic bag over the SIB before placing it on a stable, flat surface. See Figure 7.
    CAUTION:

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

  9. If you are not installing a SIB in the emptied SIB slot, install a blank SIB cover panel (part number: JNP10016-SF-BLNK2) over the slot. Hold the blank SIB cover panel vertically such that the high temperature label is on the top of the faceplate and insert it all the way into the slot until the top and bottom latches lock the unit in place (see Figure 8). Do this to ensure that the airflow inside the chassis is not disrupted.
