Remove an MX10004 Router

The following sections explain how to power off and remove an MX10004 router.

Power Off an MX10004 Router

Before you power off a Juniper Networks MX10004 router:

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

  • Ensure that you don’t need to forward traffic through the router.

  • Ensure that you have the following parts and tools available to power off the router:

    • An ESD grounding strap

    • An external management device such as a PC

    • An RJ-45-to-DB-9 rollover cable to connect the external management device to the console port on one of the Routing and Control Boards (RCBs)

To power off an MX10004 router:

  1. Connect to the router using one of the following methods:
  2. Shut down Junos OS from the external management device by using the request vmhost power-off operational mode CLI command followed by the request chassis cb slot slot-number offline. These commands shut down a single RCB gracefully and preserve system state information. When you issued this command on a redundant system, it shuts down the partner RCB. A message appears on the other RCB console, confirming that the operating system has halted. For example, if you want to shut down the backup RCB, issue the command on the primary RCB. You view the output on the backup RCB.
  3. 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 router chassis. One ESD point is located above the status LED panel on the front of the chassis, and the other ESD point is located in the rear below the power supplies.
  4. Disconnect power to the router by performing one of the following tasks:

    • AC power supply—Set the enable router switch to the off (O) position and gently pull out the coupler for the power cord from the faceplate.

    • DC power supply—Switch the circuit breaker on the panel board that services the DC circuit to the off position.

  5. Remove the power source cable from the power supply faceplate:

    • AC power supply—Remove the power cord from the power supply faceplate by detaching the power cord retainer and gently pulling out the power cord plug that is connected to the power supply faceplate.

    • DC power supply—Loosen the thumbscrews by securing the DC power connector on the power source cables. Remove the power source cables from the power supply.

  6. Remove any remaining cables and optics before you remove the chassis from the rack.

Remove an MX10004 Router from a Four-Post Rack Using a Mechanical Lift

Before you remove the Juniper Networks MX10004 router using a mechanical lift:

CAUTION:

When removing more than one router chassis from a rack, remove the routers in order from top to bottom.

Because of the router's size and weight, we strongly recommend that you use a mechanical lift to remove the MX10004. Lifting the chassis and removing it from a rack or cabinet requires at least three people.

Make sure the chassis is empty (contains only the fan tray controllers) before you lift it.

Note:

For instructions on removing a router without using a mechanical lift, see Manually Remove an MX10004 Router from a Four-Post Rack.

To remove an MX10004 router from a four-post rack using a mechanical lift:

  1. Remove all optics, line cards, RCBs, power supplies, fan trays, and SFBs before you attempt to move the router chassis. See the following topics:

    Ensure that all of the removed components are stored in antistatic bags.

  2. Use the appropriate Phillips (+) screwdriver to remove the screws that attach the chassis to the rack.
  3. Move the lift to the rack and position it so that its platform is centered about 0.5 in. (1.27 cm) below the bottom of the router chassis and as close to it as possible.
  4. Carefully slide the router from the mounting tray attached to the rack onto the lift.
  5. Move the lift away from the rack and lower the platform on the lift (see Figure 1).
  6. Use the lift to transport the router to its new location.

    After moving the router to its new location, install the components in the chassis or store the components in antistatic bags.

Manually Remove an MX10004 Router from a Four-Post Rack

Before you manually remove a Juniper Networks MX10004 router from a rack:

If you cannot use a mechanical lift to remove the router (the preferred method), you can remove it manually.

CAUTION:

Because of the router's size and weight, we strongly recommend that you use a mechanical lift to remove the MX10004. Lifting the chassis and removing it from a rack or cabinet requires at least three people.

Make sure the chassis is empty (contains only the fan tray controllers) before you lift it.
CAUTION:

When removing more than one router chassis from a rack, remove the routers in order from top to bottom.

To manually remove an MX10004 router from a four-post rack:

  1. Remove all optics, line cards, RCBs, power supplies, fan trays, and SFBs before you attempt to move the router chassis. See the following topics:

    Ensure that all the removed components are stored in antistatic bags.

  2. Use the appropriate Phillips (+) screwdriver to remove the screws that attach the chassis to the rack.
    Warning:

    To prevent injury, keep your back straight and lift with your legs, not your back. Do not twist your body as you lift. Balance the load evenly and be sure that your footing is firm.
  3. Position one person on each side of the rack and another in the rear of the chassis.
    Note:

    The two handles on the side of the chassis are meant only to help guide the empty chassis out of the base and rear brackets; they are not for lifting.
  4. On each side, hold the bottom of the chassis and carefully lift it up from the mounting tray attached to the rack.
  5. Carefully lift the chassis out of rack. If you have a pallet jack, move the router onto the pallet jack. See Figure 2.

  6. Carefully move the chassis to its new location.

    After moving the router to its new location, install the components in the chassis or store the components in antistatic bags.
