Removing the NFX250 Device from a Rack or Cabinet

Powering Off an NFX250 Device

If you need to power off the NFX250 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 system halt

    This command shuts down the switch 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):

    CAUTION:

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

    CAUTION:

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

  3. Attach the ESD grounding strap to your bare wrist and connect the strap to the ESD point on the chassis.
  4. Set the power switch to OFF (0) position.

Removing an NFX250 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 NFX250 device, use the procedure described in this topic. (The remainder of this topic uses rack to mean rack or cabinet.)

Note:

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.

CAUTION:

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 NFX250 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 NFX250 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.
