Removing Existing M2M Gateway from Bracket
The existing mounting bracket, which contains the M2M
Gateway and power supply, is mounted to the inside of the
control enclosure. Depending on the cabinet layout, the bracket
may be located in several different places within the control
enclosure. Typically, however, it will be located on the top of
the enclosure. Prior to removing the existing Gateway from
this bracket, ensure that all wiring interconnections have been
removed from the existing M2M Gateway, as described in the
preceding section. In addition, make note of the orientation
of the existing Gateway on the mounting bracket. The new
M2M Gateway must be installed in the same orientation.
Remove the existing Gateway by unscrewing the 5/16” head
sheet metal screws located at the four corners of the Gateway
(
Figure 6
). Set these screws aside, as they will be reused for
the new M2M Gateway.
