Removing the MX10008 Router

 

Powering Off an MX10008 Router

Note

Use the following procedure to power off an MX10008.

Before you power off an MX10008:

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 RCBs

To power off an MX10008:

  1. Connect to the router using one of the following methods:
  2. Shut down Junos OS from the external management device by issuing the request vmhost halt operational mode CLI command. This command shuts down the router gracefully and preserves system state information. A message appears on the console, confirming that the operating system has halted.

    You see the following output (or something similar, depending on the hardware being shut down) after entering the command:

    Caution

    The final output of any version of the request vmhost halt command is the “The operating system has halted.” Wait at least 60 seconds after first seeing this message before following the instructions in Step 4 and Step 5 to power off the router.

  3. Attach the grounding strap to your bare wrist and to one of the two site ESD points on the chassis.
  4. Disconnect power to the router by performing one of the following tasks:

    • AC power supply—Set the enable 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 male end of the power cord connected to the power supply faceplate.

    • DC power supply—Loosen the thumbscrews 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 removing it from the rack.

Removing an MX10008 Router From a Four-Post Rack Using a Mechanical Lift

Because of the router's size and weight, we strongly recommend using a mechanical lift to install the MX10008.

Note

For instructions on installing a router without using a mechanical lift, see Manually Mounting an MX10008 in a 4-Post Rack.

Before you remove the router using a lift:

Caution

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

Ensure that you have the following parts and tools available to remove the router:

  • A mechanical lift rated for 500 lb (226.8 kg)

  • A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your mounting screws

To remove the router using a mechanical lift (see Figure 1):

  1. Use the appropriate Phillips (+) screwdriver to remove the 14 mounting screws that attach the chassis flange to the rack.
  2. Move the lift to the rack and position it so that its platform is centers about 0.5 in. (1.27 cm) below the bottom of the router chassis and as close to it as possible.
  3. Carefully slide the router from the adjustable base bracket attached to the rack onto the lift.
  4. Move the lift away from the rack and lower the lift.
  5. Use the lift to transport the router to its new location.

Manually Removing an MX10008 Router from a 4-Post Rack

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

Caution

The chassis weighs approximately 145 lb (66 kg) with only the fan tray controllers installed. Lifting the chassis and mounting it in a rack or cabinet requires at least three people.

Make sure the chassis is empty (contains only the backplane) before you lift it.

Caution

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

Before you manually remove the router from a rack:

Ensure you have a Phillips (+) screwdriver, number 2 or number 3, depending on the size of your mounting screws.

To manually remove an MX10008 from a rack:

  1. Remove all line cards, RCBs, power supplies, fan trays, SFBs, and optics before attempting to move the router chassis.

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

  2. Use the appropriate Phillips (+) screwdriver to remove the 14 mounting screws that attach the chassis flange 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 and another in the rear of the chassis. There are two handles on the side, but these handles are only meant to help guide the empty chassis out of the base and rear brackets.
  4. On each side, hold the bottom of the chassis and carefully lift it up from the base and rear brackets on the four-post rack.
  5. Carefully lift it out of the 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, reinstall the components in the chassis or store the components in electrostatic bags.
