Cisco Systems OL-31454-01 Manual De Usuario

This section describes how to connect WAN and LAN interface cables.

One or two Ethernet cables are typically provided with the router. Additional cables and transceivers can 
be ordered from Cisco. For ordering information, contact customer service. For cable pinouts, see 

Do not work on the system or connect or disconnect cables during periods of lightning activity. 
Statement 1001

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network 
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some 
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021

Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF 
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, 
detach the end away from the unit first. Statement 1026

To properly connect cables follow these steps:

Connect each WAN and LAN cable to the appropriate connector on the chassis or on an interface card.

Position the cables carefully, so that they do not put strain on the connectors. 

Organize cables in bundles so that cables do not intertwine.

Inspect the cables to make sure that the routing and bend radius is satisfactory. Reposition cables, if 
necessary.

Install cable ties in accordance with site requirements.
