Step 7Clean the flat surface to which you will affix the antenna.
Step 8Remove the protective tape from the adhesive on the bottom of the antenna cradle, then firmly press the 
cradle to the flat surface. 
Connecting a Data BRI Port
You can connect the Data BRI port to the ISDN service provider as a backup link to the WAN port in 
case the primary xDSL (general term referring to various forms of DSL, including global industry 
standard symmetrical high-speed DSL [G.SHDSL]) WAN service fails. The Data BRI connection is not 
available on the third-generation (3G) models. 
The cabling requirements for the ISDN S/T connection are as follows:
 You must provide two unshielded Category 5 cables. The first cable connects the NT1 box to the 
splitter, and the second cable connects the splitter to the wall jack.
 There are RJ-45 connectors at both ends of the default orange ISDN S/T cable. However, an 
RJ-45–to–RJ-11 ISDN S/T cable is available upon request if the wall jack at the site requires an 
RJ-11 connector. Contact your router reseller for the appropriate cable.
CautionBoth LAN and WAN ports 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).

  Connecting a Data BRI Port
Although the following procedure shows a Cisco 888W data router, this procedure applies to all 
Cisco
 880 series router with a Data BRI port.
To connect the Data BRI port to the ISDN service provider, follow these steps:
Step 1Connect one end of the orange ISDN S/T cable to the Data BRI port on the router. Figure 3-13 shows a 
Data BRI connection.
Figure 3-13 Connecting the Data BRI Port to the ISDN Line
Step 2Connect the other end of the orange ISDN S/T cable to the S/T port on the NT1 box.
Step 3Connect the first unshielded CAT 5 cable from the U-port on the NT1 box to the telephone line port on 
the splitter. 
Step 4Connect the second unshielded Category 5 cable from the telecommunication service port on the splitter 
to the wall jack to allow a link to the network service provider.

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
To connect the router to a global industry standard symmetrical high-speed DSL (G.SHDSL) line, 
very-high-speed digital subscriber line 2 (VDSL2) port, or an ADSL2+ line, follow these steps: 
Step 1Connect one end of an RJ-11 (RJ-45 on 880 E models) cable to the port on the router. See Figure 3-16.
Figure 3-16 Connecting the xDSL Line
Step 2Connect the other end of the cable to the DSL wall jack.
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.

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
Figure 3-17 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 “Connecting the AC Adapter” section on page 3-18.
NoteBe sure that the internal PoE is enabled for this connection procedure to work.

  Connecting the AC Adapter
WarningThis product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that 
a fuse or circuit breaker no larger than 120VAC, 20A U.S. (240VAC, 16 to 20A international) is used on 
the phase conductors (all current-carrying conductors). The fuse or circuit breaker must have 
adequate safety approvals recognized by the country of usage. Statement 119
WarningThis unit might have more than one power supply connection. All connections must be removed to 
de-energize the unit. Statement 1028
To connect your Cisco 860 series or Cisco 880 series ISR to an AC power outlet, follow these steps:
Step 1Connect the router to an AC power outlet as shown in Figure 3-18.

Connecting an FXS Line
Use a standard straight-through RJ-11 modular telephone cable to connect an Foreign Exchange Service 
(FXS) port to a telephone or fax machine. 
WarningThis 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 associated circuit-board when the ringer is active. The ringer is activated by an incoming 
call.
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
WarningFor 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.
