Removing an M7I DC Power Cable


Before removing a DC power cable from an M7i router with only one power supply, you must power off the router. To remove a DC power cable from the router:

  1. Shut off the power flowing from the external power sources, so that the voltage across the leads of the power cables is 0 V. Ensure that there is no chance that the cable leads might become active during the procedure.
  2. Press the power switch on the power supply faceplate to the OFF (O) position.Note

    If you are power cycling the power supply rather than shutting it off for a time, wait at least 60 seconds after turning it off before turning it back on. If you need to power it off again, wait for at least 60 seconds after powering it on.

  3. Using a number 1 Phillips screwdriver, turn the screw on each field-wiring terminal counter-clockwise to loosen the terminal connector from around the cable lug.
  4. Remove the DC cables from the terminal connectors and from the hook located on the faceplate to the right of the field-wiring terminals.
  5. Verify that the removed DC cables are not touching or blocking access to any router components.
