The following cables are not included with the router. You need to order them
separately.
•Modem cable—For connecting the router console port to an asynchronous
modem for dial backup and remote management.
•Orange ISDN S/T cable—For connecting devices to the ISDN S/T port.
Caution Both LAN and WAN ports can use RJ-45 connectors. Use caution when
connecting cables to these connectors. To avoid damage to the router, do not
connect telephone-network voltage (TNV) circuits (such as ISDN or DSL
circuits) to safety extra-low voltage (SELV) circuits (such as LAN circuits).

Nonwireless Routers
Portions of this guide do not apply to nonwireless models of the Cisco 850 series
and Cisco 870 series routers. Some illustrations show the router with antennas
attached, whereas the nonwireless routers do not have antennas or antenna
connectors on the back panel. However, except for the “Connect the Antenna to
the Wireless Router (Optional)” section, the connection procedures are the same
for wireless and nonwireless router models.
Read the Safety Warnings and Guidelines
Before you begin to connect your router, read the Regulatory Compliance and
Safety Information for Cisco 800 Series Routers document that is shipped with the
router. This document provides important safety warnings and guidelines.
Remove the Caution Sticker
Locate the yellow caution label that covers the LAN ports. Simply peel off the
label and the LAN ports are ready for use. Be sure that you do not connect ISDN
telephone lines to these LAN ports.

To connect the antenna or antennas to a wireless router, follow these steps:
Step 1 Attach each antenna to a reverse-polarity threaded Neill-Concelman (RP-TNC)
connector on the back of the router and tighten the connector hand-tight.
Step 2 After you connect the antenna to the back of the router, orient the antenna so that
it is straight up.

Connect the Power-over-Ethernet Module to the Cisco 870 Series Router (Optional)
Connect the Power-over-Ethernet Module to the
Cisco 870 Series Router (Optional)
Power-over-Ethernet (PoE) is supported on the Cisco 870 Series routers only. If
you purchased a PoE module, connect all four Ethernet cables on the PoE module
to the four LAN Ethernet ports on the Cisco 870 Series router. (See Figure 1-5.)
Make sure that you connect all four Ethernet cables.
If the cables are too close together for easy insertion, move the plastic cable guard
away from the connector end of the cables.
Caution To ensure proper PoE module operation, do not connect the PoE module power
supply to the PoE module before you connect the PoE module to the router.
Although Figure 1-5 shows the Cisco 871 router connected to a PoE module, this
connection works for all router models in the Cisco 870 series.
Note When you connect a device (such as a PC or IP phone) to the PoE module, you
may notice a 1- to 2-second delay before the LED indicator for the port comes on.
