Connecting an xDSL Line
WarningHazardous 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

CautionCisco Systems DSL WAN Interfaces are tested for compliance with regulatory standards such as FCC 
Part 68, ITU-T K.21, IEC 61000-4-5, and CSA/EN/IEC/UL 60950-1. These standards assume Primary 
Protection devices protect the Customer Premise Equipment (CPE). These devices are normally installed 
by the service provider, local exchange carrier or qualified service person and are located at the telecom 
service provider entrance, network interface box, or demarcation point. See Figure 3-28 for the likely 
location of the primary protection device. The primary protection device must be suitable for the xDSL 
interface employed. Please contact your sales team or qualified service person for further information 
and installation.
CautionTo reduce the risk of fire, use only No. 26 AWG or larger (e.g., 24 AWG) UL Listed or CSA Certified 
Telecommunication Line Cord.
WarningDo not use this product near water; for example, near a bath tub, wash bowl, kitchen sink or laundry 
tub, in a wet basement, or near a swimming pool. Statement 1035
WarningAvoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote 
risk of electric shock from lightning. Statement 1038
WarningTo report a gas leak, do not use a telephone in the vicinity of the leak. Statement 1039
WarningThere is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with 
the same or equivalent type recommended by the manufacturer. Dispose of used batteries according 
to the manufacturer’s instructions. Statement 1015

CautionThe 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.
NoteThe 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
WarningThis unit might have more than one power supply connection. All connections must be removed to 
de-energize the unit. Statement 1028
WarningThis 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.
NoteThe 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.
NoteBe sure that the internal PoE is enabled for this connection procedure to work.

Figure 3-30 Connecting PoE for the Cisco 880 and the Cisco 890 Series Routers
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 1-33 and Figure 1-35.
Connecting the AC Adapter
WarningThe device is designed to work with TN power systems. Statement 19
WarningThis product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that 
the protective device is rated not greater than: 
120 VAC, 20 A U.S. (240 VAC, 16 to 20 A international). Statement 1005
WarningThis unit might have more than one power supply connection. All connections must be removed to 
de-energize the unit. Statement 1028
NoteThe Cisco 892FSP utilizes a single 4-pin power connector type. Figure 3-33 shows the pin number
