3.1.1 Local -48Vdc Source

power source and supports a second (2

Using the leftmost opening, slice open the
rubber grommet and insert one or two DC
Power cable. Be careful when cutting an
opening in the rubber grommet since you will

NOTE:
you can refer to steps 7 to 12 for the
installation of the AC Power Cable option for
more details about inserting the cable through
the rubber grommet.
