Removing the CTP151 Device from a Rack or Cabinet


If you need to relocate an installed CTP151 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.

Before removing the device from a rack:

  • 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 CTP Safety Guidelines and Warnings.

  • 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.

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.

To remove the CTP151 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.
