Remove the PTX10008 Router

To power off and remove a PTX10008 router, read the following sections:

Power Off a PTX10008

Before you power off a PTX10008 router:

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

  • Ensure that you do not 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 RCBs

To power off a PTX10008 router:

  1. Connect to the router using one of the following methods:
  2. Shut down Junos OS from the external management device. On standard Junos OS systems, you can use the request vmhost halt operational mode CLI command. On Junos OS Evolved systems use the request system shutdown power-off operational mode CLI command. These 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.” message. 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. 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. One ESD point is located above the status LED panel on the front of the router 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 plug 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.

Remove a PTX10008 from a Four-Post Rack Using a Mechanical Lift

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.

The router chassis weighs approximately 145 lb (66 kg) with only the fan tray controllers installed. Because of the router's size and weight, we strongly recommend that you use a mechanical lift to remove the PTX10008. 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 installing a router without using a mechanical lift, see Remove a PTX10008 Manually from a Four-Post Rack.

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

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

    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 or the mounting brackets attached to the rack onto the lift.
  5. Move the lift away from the rack and lower the platform on the lift.
  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.

Remove a PTX10008 Manually from a Four-Post Rack

Before you manually remove the router from a rack:

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

CAUTION:

The chassis weighs approximately 145 lb (66 kg) with only the fan tray controllers installed. Because of the router's size and weight, we strongly recommend that you use a mechanical lift to remove the PTX10008. 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.

To manually remove a PTX10008 from a rack:

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

    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.
    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 rack.
  4. On each side, hold the bottom of the chassis and carefully lift it up from the mounting tray or mounting brackets.
  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, install the components in the chassis or store the components in antistatic bags.
