Cable Connection Procedures for Cisco 2800 Series Routers
OL-5787-02
Connecting WAN, LAN, and Voice Cables
Connecting Routers to Backup Power
If your router uses the Cisco Redundant Power System (RPS), refer to the Cisco Redundant Power
System Hardware Installation Guide for instructions about the power connections. You can access this
document at:
http://www.cisco.com/en/US/docs/routers/access/rps/hardware/installation/guide/rpshim.html.
Caution
Before connecting the RPS to the router, make sure that either the RPS is in standby mode or the RPS
AC power is disconnected. Connecting the RPS to AC power automatically places the RPS in active
mode.
Note
The Cisco 2801 router does not support an RPS.
Connecting WAN, LAN, and Voice Cables
This section describes how to connect the WAN, LAN, and voice interface cables. It covers the following
topics:
•
Ports and Cabling, page 9
•
Connection Procedures and Precautions, page 11
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, refer
to the
Cisco Modular Access Router Cable Specifications document.
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
Warning
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
Warning
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
Ports and Cabling
Table 3 summarizes some typical WAN, LAN, and voice connections for Cisco 2800 series routers. The
connections summarized here are also described in detail in the following documents:
