Removing the PTX10016 Router
To power off and remove a PTX10016 router, refer to the following sections:
Powering Off a PTX10000
Before you power off a PTX10000:
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 Control Boards
To power off a PTX10000:
- Connect to the router using one of the following methods:
Connect a management device to the console (
CON) port on a Control Board by following the instructions in Connecting a PTX10000 Router to a Management Console.
Connect a management device to one of the two management (
MGMT) ports on the control board by following the instructions in Connecting a PTX10000 to a Network for Out-of-Band Management.
- 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:
Shutdown NOW!

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.
- Attach the grounding strap to your bare wrist and to one of the two site ESD points on the chassis.
Disconnect power to the router by performing one of the following tasks:
AC power supply—Set the enable router 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.
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.
- Uncable the router before removing it from the rack.
Removing a PTX10016 From a 4-Post Rack Using a Mechanical Lift
Because of the router's size and weight, we only recommend using a mechanical lift to install the PTX10016.
Before you remove the router using a lift:
Ensure that the rack is stable and secured to the building.
Ensure there is enough space to place the removed router in its new location and along the path to the new location. See PTX10000 Clearance Requirements for Airflow and Hardware Maintenance.
Review the chassis lifting guidelines described in QFX10002 Installation Safety Guidelines.
Ensure that the router has been safely powered off (see Powering Off a PTX10000).
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 1000 lbs. (453.6 kg)
A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack-mounting screws
To remove the router using a mechanical lift (see Figure 1):
- Use the appropriate Phillips (+) screwdriver to remove the 12 mounting screws that attach the chassis front-mounting brackets to the rack.
- 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.
- Carefully slide the router from the adjustable mounting brackets attached to the rack onto the lift.
- Move the lift away from the rack and lower the lift.
- Use the lift to transport the router to its new location.
