Power Off an ACX5400 Router

Before you power off an ACX5448 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
A Phillips number 2 screwdriver

To power off your ACX5400 router:

Connect to the router using one of the following methods:
- Connect a management device to the console (CON) port on the router. For instructions about connecting a management device to the console (CON) port, see Connect an ACX5400 Router to a Management Console.
- You can shut down the router from a management device on your out-of-band management network. For instructions about connecting a management device to the management (MGMT) port, see Connect an ACX5400 Router 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:
```
Initiating vmhost halt... ok
Initiating Junos shutdown...  shutdown: [pid 14318]
Shutdown NOW!
ok
Junos shutdown is in progress...
*** FINAL System shutdown message  ***                        

System going down IMMEDIATELY                                                  

...
...  
Operating system  halted.
Please press any key to reboot.
```
Wait until a message appears on the console confirming that the operating system has halted. For more information about the command, see the CLI Explorer.
Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
Disconnect power to the router by performing one of the following tasks:
- AC power supply—If the AC power source outlet has a power switch, set it to the off (O) position. If the AC power source outlet does not have a power switch, gently pull out the power cord plug connected to the power source outlet.
- 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 socket end of the power cord connected to the power supply faceplate.
- DC power supply—Remove the screws securing the ring lugs attached to the power source cables to the power supply module (PSM) using the screwdriver, and remove the power source cables from the PSM. Replace the screws on the terminals and tighten them.
Uncable the router before removing it from the rack or cabinet.

Remove an ACX5400 Router from a Rack or Cabinet

Before removing your ACX5400 router from its rack:

Ensure that you have the following parts and tools available:

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

If you need to relocate an installed ACX5400 router, use the procedure described in this topic.

Note:

When you remove multiple devices from a rack, remove the device in the top of the rack first and proceed to remove the rest of the devices from top to bottom.

Ensure that the rack is stable and secured to the building.
Ensure that there is enough space to place the removed router in its new location and along the path to the new location.
Read General Safety Guidelines and Warnings.
Use the appropriate power-off sequence to safely power off the device. See Power Off an ACX5400 Router.
Disconnect the power cords.
Ensure that you have disconnected any cables or wires attached to the router ports.

To remove an ACX5400 router from a rack or cabinet:

Have one person support the weight of the router while another person uses the screwdriver to remove the front mounting screws that attach the chassis mounting rails to the rack or cabinet.
Slowly slide the router out of the rack, with the mounting rails attached to its sides.
Use the screwdriver to remove the mounting screws that attach the mounting blades attached to the rear of the rack or cabinet.
Place the removed screws and mounting blades in a labeled bag. You will need them when you reinstall the chassis.
Transport the router to your new location.
