CHAPTER 2: Introduction

Instead of single connectors, the two ports on CAT5 Expansion Cards consist of three RJ-45 sockets each,
because three 4-pair cables are required to carry all of the signals necessary for expansion. The ports of the
regular Cards and the CAT5 Cards are shown in Figures 2-9 and 2-10; the pairing of the CAT5 RJ-45 connectors
is shown in Figure 2-11.

If you are using regular Expansion Transmit and Receive Cards, you will run a regular Expansion Cable
(shown in Figure 2-12) between a Transmit/Receive Card pair. This cable is available in stock lengths of 10feet
(3 m, product code KV1600), 25 feet (7.6 m, KV160025), 50 feet (15.2 m, KV160050), and 100 feet (30.5 m,
KV160100). If you are using CAT5 Expansion Transmit and Receive Cards, you will run three four-pair, straight-
through-pinned, solid-conductor CAT5 twisted-pair cables (product code EYN737MS-MM, shown in
Figure 2-13) between a Transmit/Receive Card pair. This CAT5 cable is available in stock lengths of 10 feet
(3 m), 50 feet (15.2 m), 100 feet (30.5 m), or 250 feet (76.2 m), or you can order it in custom lengths.
