You can crimp your own LAN cables for use with the ONS 15454. Use a cross-over cable when
connecting an ONS 15454 to a hub, LAN modem, or switch, and use a LAN cable when connecting an
ONS 15454 to a router or workstation. Use CAT-5 cable RJ-45 T-568B, Color Code (100 Mbps), and a
crimping tool. Figure 1-18 shows the wiring of an RJ-45 connector. Figure 1-19 shows a LAN cable
layout, and Table 1-5 shows the cable pinouts. Figure 1-20 shows a cross-over cable layout, and
Table 1-6 shows the cross-over pinouts.
