Console and Auxiliary Port Cables and Pinouts

The router arrives with a console and auxiliary cable kit, which contains the cable and adapters you need

to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to the

router. The console and auxiliary cable kit includes:

• RJ-45-to-RJ-45 rollover cable

• RJ-45-to-DB-9 female data terminal equipment (DTE) adapter labeled TERMINAL

• RJ-45-to-DB-25 female DTE adapter labeled TERMINAL

• RJ-45-to-DB-25 male data communications equipment (DCE) adapter labeled MODEM

Appendix C Cable Specifications Console and Auxiliary Port Cables and Pinouts Identifying a Rollover Cable You can identify a rollover cable by comparing the two modular ends of the cable. Holding the cables side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See Figure C-1.

Appendix C Cable Specifications Fast Ethernet Port Cables and Pinouts Fast Ethernet Port Cables and Pinouts The 10BaseT/100BaseTX Fast Ethernet ports support IEEE 802.3 and IEEE 802.3u specifications for 10-Mbps and 100-Mbps transmission over unshielded twisted-pair (UTP) cables. Each Fast Ethernet port on the router has an RJ-45 connector to attach to Category 3 or Category 5 UTP cables. Cisco Systems does not supply Category 3 or Category 5 UTP RJ-45 cables; these cables are available commercially.

Single-mode transmission is useful for longer distances, because there is a single transmission path within the fiber and smear does not occur. In addition, chromatic dispersion is also reduced because laser light is essentially monochromatic.
