Caution The primary WAN port is designed for an RJ-45 connector only. Damage to the primary WAN port may
occur if a non-RJ-45 connector is inserted.
Note The DSL line must be provisioned by your service provider and correctly configured so that the LED
shows the carrier detect (CD) status. On Cisco 860VAE routers, check the DSL Link LED.
Connecting Power over Ethernet
Warning
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit.
Statement 1028
Warning
This product must be connected to a power-over-ethernet (PoE) IEEE 802.3af compliant power source
or an IEC60950 compliant limited power source.
Statement 353
Figure 3-30 shows how to connect the 48-VDC Power over Ethernet (PoE) power adapter to your router.
The PoE adapter provides power to ports 0 and 1 of the 4-port 10/100 FE switch on the Cisco 880 series
routers and ports 0,1, 2, and 3 of the 8-port 10/100 FE switch on the Cisco 890 series routers.
Note The router must also be connected to an AC power outlet through a 12-VDC adapter. To connect the
router to an AC outlet, see the“Connecting the AC Adapter” section on page 3-5.
Note Be sure that the internal PoE is enabled for this connection procedure to work.

The Cisco 880 series ISRs with embedded WLAN antennas require a single external power supply: a
30-W power supply for non-POE-enabled routers or a 60-W power supply for POE-enabled routers. For
the back panels of some of these routers, see Figure 1-29 and Figure 1-31.
Connecting the AC Adapter
Warning
The device is designed to work with TN power systems.
Statement 19
Warning
Thisproduct reliesonthe building’sinstallationforshort-circuit (overcurrent)protection. Ensurethat
the protective device is rated not greater than:
120 VAC, 20 A U.S. (240 VAC, 16 to 20 A international).
Statement 1005
Warning
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit.

Connecting an FXS Line
Use a standard straight-through RJ-11 modular telephone cable to connect a Foreign Exchange Service
(FXS) port to a telephone or fax machine.
Warning
This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do
not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11
port, or the associatedcircuit-board when the ringer is active. The ringer is activated by an incoming
call.
Statement 1042
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
Warning
For connections outside the building where the equipment is installed, the following ports must be
connected through an approved network termination unit with integral circuit protection: FXS.

Note If you have specified the use of a private line automatic ringdown (PLAR) off-premises extension (OPX)
connection mode for an FXO voice port (with loop resistance less than 8000 Ohm), you must ensure that
the soft-offhook option is enabled on the port.

This option allows a stepped offhook resistance during seizure, which avoids overloading the circuit
during offhook in the event that ringing voltage is present on the circuit at the same time as the trunk
seizure. The stepped offhook resistance is initially set to 800 Ohms, then adjusts to 50 Ohms when
ringing voltage is not present.
To enable the soft-offhook command on the port, and to access the connection command with plar opx
syntax, see the Cisco Command Lookup Tool.
Connecting a Voice ISDN BRI Line
Use a straight-through RJ-45 cable to connect the voice BRI port to the ISDN network through a
telephone outlet or other device.
Caution To prevent damage to the router, be sure to connect the BRI cable to the BRI connector only and not to
any other RJ-45 connector.
To connect the voice BRI line, follow these steps:
Step 1 Connect one end of a straight-through RJ-45–to–RJ-45 cable to the Voice BRI port.
Note When the interface is configured as NT and is connecting to a TE device, use a crossover cable.
See Table A-27.
