Removing an MX10016 Router
Before you remove an MX10016, you must first poweroff the router, and then follow the procedure to remove the router from the rack.
Powering Off an MX10016 Router
Before you power off an MX10016:
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 an MX10016:
- Connect to the router using one of the following methods:
Connect a management device to the console (
CON) port on an RCB by following the instructions in Connecting an MX10016 Router to a Management Console.Connect a management device to one of the two management (
MGMT) ports on the RCB by following the instructions in Connecting an MX10016 to a Network for Out-of-Band Management.
- Shut down Junos OS from the external management device
by using 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 System 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.
- Wrap and fasten one end of an ESD strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
To disconnect power to the router:
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.
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 faceplate.
- Uncable the router before removing it from the rack.
Removing an MX10016 Router From a Four-Post Rack Using a Mechanical Lift
Because of the size and weight of the router, we strongly recommend using a mechanical lift to remove the MX10016.
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 uninstalled router in its new location and along the path to the new location (see Clearance Requirements for Airflow and Hardware Maintenance for an MX10016).
Review the chassis lifting guidelines described in MX10016 Chassis Lifting Guidelines.
Ensure that the router has been safely powered off (see Powering Off an MX10016 Router).
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 lbs. (226.8 kg)
A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack-mounting screws
To removethe router using a mechanical lift (see Figure 1):
- Use the appropriate Phillips (+) screwdriver to remove the 14 mounting screws that attach the chassis flange to the rack.
- Move the lift to the rack and position the lift so that its platform is centered about 0.5 in. (1.27 cm) below the bottom of the router chassis and as close to the chassis as possible.
- Carefully slide the router from the adjustable base 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.
