System 75 XE to R8si (Blowback)

Remove the control cabinet [75 XE upgrade]

Return to Task List

To remove the control cabinet from the bottom of the port network, you must completely dismantle the system.


Danger! A port cabinet may weigh as much as 125 pounds and requires 2 handlers to unstack the cabinets. If third or fourth cabinet is to be removed, remove the front door, power supply, and circuit packs to lighten the load. Use caution to avoid injury.

  1. Verify that all of the power, grounding, TDM, and connector cables have been disconnected.

  2. Ensure that there is adequate space available to place each cabinet in an out-of-the-way location as the port network is dismantled.

  3. Remove the cabinet clip between each cabinet.

  4. Remove each port cabinet from the stack, and put it in a safe place.

  5. If the control cabinet is earthquake mounted, remove the hardware securing the cabinet to the floor.

  6. Move the existing control cabinet out of its present location. It will not be reused, so it can be removed at this time.
