4. Now configure the DIP switches on your Receive Modules. Like the Transmit Modules, each of the Receive
Modules has sixteen dual-RJ-45 transmit ports on it, numbered 1 through 16 from left to right, as shown in
Figure 7-5 on the previous page. Each port has three two-position DIP switches that you need to set for the
length of the Category 5 cable that will be attached to the port. The locations of these DIP switches are
shown in Figure 7-6, and their possible settings are shown in Figure 7-7. For any given Receive port, leave
all of the switch positions set to OFF if the cable you’ll be attaching to that port isn’t more than 125 ft.
(38.1 m) long. If the cable is longer than 125 ft. (38.1 m) but not more than 225 ft. (68.6 m), move the left-
hand position in each switch to ON. If the cable is longer than 225 ft. (68.6 m), up to the Switch’s
maximum supported CAT5 expansion-cable length of 250 ft. (76.2 m), move all of the switch positions to
ON.
