INSTALLING THE ROUTER
Install the router using the following steps:
1.
Make sure the Type 2 base plate is correctly wired,
installed, and fastened to the electrical enclosure.
2.
Check for continuity on all network and power wiring.
3.
Make sure all network channels are terminated with
the correct number and type of terminator. Either one
or two terminator(s) can be installed in unused screw
terminals at the end of a network run.
4.
Insert the router into the Type 2 base plate.
a.
Align the network access jacks on the router
with the arrowhead on the Type 2 base plate
(the arrow should point toward the jacks).
b.
Firmly press router into the base plate to make
sure the module is properly seated in its base
plate connector.
NOTE: The router can be hot plugged. There is no
need to disconnect power when installing
the module. If power is present, the Power
LED lights. If power is not present, the
Power LED is off.
5.
Screw the two 8-32 x 3/8 in, (9.5 mm) screws into the
threaded inserts in the base plate.
6.
Configure the router as described in the appropriate
software user guide.
7.
See Troubleshooting section if necessary.
