MX10004 Line Card Maintenance

Maintaining Juniper Networks MX10004 routers includes removing and reinstalling line cards.

Line cards in the MX10004 are field-replaceable units (FRUs) that can be installed in any of the line card slots on the front of the chassis. The line cards are hot-insertable and hot-removable: you can remove and replace them without powering off the router or disrupting router functions.

Handle and Store MX10004 Line Cards Properly

The MX10004 line cards have fragile components. To avoid damaging the line cards, be sure you follow safe handling practices.

Handle an MX10004 Line Card Properly

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

To handle an MX10004 line card properly:

  1. Orient the line card 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 by the connector edge. The connectors are fragile and the line card won’t seat properly if the connector is damaged. See Figure 1.

  4. If you must rest a line card on an edge, place a cushion between the edge and the surface.
    CAUTION:

    Do not stack line cards 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.

Store a Line Card Properly

You must store line cards either in the chassis or in a spare shipping container, horizontally and sheet-metal side down. Don’t stack these units on top of one another or on top of any other component.

You must 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 antistatic bags are fragile, two people should insert the line card into the bag.
Note:

The MX10K-LC9600 line cards are shipped with a protective plastic cover on the fabric interface connectors. The plastic cover keeps the connectors clean and free of dust and other particles. When you remove MX10K-LC9600 line card from the router, re-insert the protective plastic cover on the fabric interface connectors and then place the line card in an antistatic bag or on an antistatic mat placed on a flat, stable surface.

To store a line card properly in an antistatic bag:

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

If you must insert the line card into an antistatic 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.

Bring an MX10004 Line Card Online or Take It Offline

The offline/online (OFF) button is recessed below the faceplate directly below the status (STS) LED. You can bring any of the MX10004 line cards online or take them offline using either of these two methods:

  • Press the OFF button with a non-conductive pin tool, such as a toothpick, until the STS LED turns off after about 5 seconds.

  • Issue the CLI command:

Install an MX10004 Line Card in the Router Chassis

Before you install a line card in the router chassis:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

  • Review how to handle and store the line card. See Handle and Store MX10004 Line Cards Properly.

  • Inspect the connector edge of the line card for physical damage. Installing a damaged line card might damage the router.

  • Ensure that the router has sufficient power to power the line card while maintaining its n+1 power redundancy. To determine whether the router has enough power available for the line card, use the show chassis power detail command.

  • Ensure that you have the following parts and tools available to install a line card in the router:

    • ESD grounding strap

    • Phillips (+) screwdriver, number 2

To install an MX10004 line card in the router chassis:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis. An ESD point is located above the status LED panel on the front of the router chassis. See Figure 2.

  2. Remove the line card cover by grasping the handles and pulling them straight out to expose the slot for the line card. See Figure 3.
    Figure 3: Remove the Cover for a Line Card Remove the Cover for a Line Card
    CAUTION:

    Do not lift the line card by holding the edge connectors or the handles on the faceplate. Neither the handles nor the edge connectors can support the weight of the line card. Lifting the line card by the handles or edge connectors might bend them. If the edge connectors are bent, you may not be able to seat the line card in the chassis properly. See Figure 4.
    Figure 4: Line-Card Connectors Line-Card Connectors
  3. Remove the line card from the antistatic bag and inspect it for any damage before you install it in the chassis.
  4. If you are installing MX10K-LC9600, remove the protective plastic cover on the fabric interface connectors. Save the plastic cover for future use (see Figure 5)
    Figure 5: Remove Protective Plastic Cover from the MX10K-LC9600 Interface Connectors Remove Protective Plastic Cover from the MX10K-LC9600 Interface Connectors
  5. Grasp and lift the line card by the sides.
  6. Slide the line card all the way into the slot until the handle holes align. See Figure 6.
    Figure 6: Insert the Line Card into the Slot and Rotate the Handles Insert the Line Card into the Slot and Rotate the Handles
  7. Rotate the handles simultaneously until the line card is fully seated and the handles are vertical.
  8. If the router is not powered, the line card automatically comes online when you apply power to the router. If you are adding the line card to a running system, issue the following command to bring the line card online:

You can install the optional cable management kit after you install the line cards.

Remove a Line Card from an MX10004 Router Chassis

If you have the optional line-card cable management system, it’s not necessary to remove the cable management system before removing the line card.

Before you remove a line card from the router chassis:

CAUTION:

Do not remove the line card unless you have a replacement line card or a line card cover (JNP10K-LC-BLNK) available.
Note:

If you are not installing another line card into the empty card slot within a short time, install the line card cover into the slot to maintain proper airflow in the card cage.

The air filters in the line card covers will prevent dust and other particles entering the chassis. If an empty line card slot is not covered, dust and other particles may accumulate on the connector pins of the installed line cards and SFBs and affect the performance of the router.

To remove a line card from an MX10004 router chassis:

  1. Place the antistatic bag or 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 one of the ESD points on the chassis. An ESD point is located above the status LED panel on the front of the router chassis. See Figure 2.
  3. Label the cables connected to each port on the line card so that you can reconnect the cables to the correct ports.
  4. Issue the following CLI command to take the line card offline:
  5. Unscrew the line card from the chassis by continually turning the handles to the left until the line card is fully unseated. See Figure 7.
    Figure 7: Remove an MX10004 Line Card Remove an MX10004 Line Card
  6. Using the handles, slide the line card halfway out of the chassis.
    CAUTION:

    Do not stack line cards on top of one another or on top of any other component. Place each line card separately in the antistatic bag or on the antistatic mat placed on a flat, stable surface.
    CAUTION:

    Be prepared to support the full weight of the line card as you slide it out of the chassis.
  7. Grasp both sides of the line card at midpoint and remove the line card from the chassis. Either have someone assist you in placing the line card into the antistatic bag or rest the card on the antistatic mat. Take care not to bump or store the line cards on the connectors. See Figure 4.
  8. If you removed an MX10K-LC9600 from the router, re-insert the protective plastic cover on the fabric interface connectors of the line card to keep the connectors clean and free of dust and other particles (see Figure 8).
    Figure 8: Insert Protective Plastic Cover on MX10K-LC9600 Interface Connectors Insert Protective Plastic Cover on MX10K-LC9600 Interface Connectors
  9. If you are not installing a line card in the emptied line-card slot within a short time, install a cover over the slot. Do this to protect the interior of the chassis from dust or other foreign substances and to ensure that the airflow inside the chassis is not disrupted.

Install the Cable Management System—JLC-CBL-MGMT-KIT

The Juniper Networks JLC-CBL-MGMT-KIT cable management system is an optional, orderable kit. This kit organizes and protects optical cabling attached to the line cards. After you install a line card, you can still remove the line card without needing to remove the cable management system.

Ensure that you have the following tool available to install the cable management system on a line card:

Phillips (+) screwdriver, number 2

To install the cable management system:

  1. Open the shipping carton for the cable management system and check that you have:

    • Two handle extensions

    • One cable tray
