Removing the NFX150 Device from a Rack or Cabinet

Powering off an NFX150 Device

To power off the NFX150 device, follow the procedure in this topic.

Before you power off the switch:

Ensure that you have the following parts and tools available to power off the switch:

  • An electrostatic discharge (ESD) grounding strap

  • An external management device such as a PC

  • A cable to connect the external management device to the console port (CON) or management port (MGMT) on the device

To power off the device:

  1. Connect the management device (such as a PC) to the console (CON) port or the management (MGMT) port on the device:
  2. From the PC connected to the device, issue the following operational mode CLI command:

    user@switch> request vmhost halt

    This command shuts down the device gracefully and preserves system state information. A message displays on the console confirming that the operating system has halted.

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


    The final output of any version of this command is the The operating system has halted. Please press any key to reboot. message. Wait for at least 60 seconds after seeing this message and before following the instructions in Steps 3 and 4 to power off the device.


    Ensure that you have halted your system safely before turning off the power supply.

  3. Wrap and fasten one end of the ESD grounding strap around your wrist and connect the other end to a site ESD point.
  4. Set the power switch to OFF (O) position.

Removing an NFX150 Device from a Rack or Cabinet

Before removing the device from a rack:

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

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

  • A labeled bag to hold the removed screws.

If you need to relocate an installed NFX150 device, use the procedure described in this topic. (The remainder of this topic uses rack to mean rack or cabinet.)


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


At least two people must be available to lift a device chassis out of a rack—one person to unscrew the mounting screws from the brackets and the second person to hold the chassis.

  • Ensure that the rack or cabinet is stable and secured to the building.

  • Ensure that there is enough space to place the removed device in its new location and along the path to the new location.

  • Read General Safety Guidelines and Warnings, with particular attention to Chassis Lifting Guidelines for NFX150 Devices.

  • Ensure that the device has been safely powered off and that you have unplugged (disconnected) the power cords.

  • Ensure that you have disconnected any cables or wires attached to the device.

To remove an NFX150 device from a rack:

  1. Use the appropriate Phillips (+) screwdriver to remove the mounting screws that attach the chassis front-mounting brackets to the rack.
  2. Place the removed screws in a labeled bag. You will need them when you reinstall the chassis.
  3. Lift the chassis from the rack and carefully move the chassis to its new location.
