Connect the Interfaces
To connect a UC 520 to a WAN, PSTN, and ISDN, perform these steps in any order:
Step 1
For connecting to a cable or DSL modem: Connect an RJ-45 cable to the WLAN port on the
front panel of the UC 520. Connect the other end of the cable to the cable or DSL modem.
Step 2
For connecting to an ISDN line: Connect an RJ-45 cable to one of the BRI or T1/E1 PRI ports
on the front panel of the UC 520 and connect the other end of the cable to a PC or hub or to
a ISDN wall jack.
Step 3
For connecting to a PSTN: Connect an RJ-11 cable to one of the FXO ports on the front panel
of the UC 520 and connect the other end of the cable to a PSTN line or a station interface on
a PBX.
Connect the Devices
To connect wireless access points, Cisco Unified IP phones, and other devices to a UC 520 or a Cisco
Catalyst Express 520 switch, follow these steps in any order:
Step 1
Install and connect Cisco Unified IP phones to the PoE ports on the front panel of the UC 520
and if installed, to PoE ports on front of the switch.
Note
The PoE ports on the UC 520 provide up to 15.4 W of power to connected
Cisco prestandard and IEEE 802.3af-compliant powered devices, with a maximum of
80W total on the eight PoE ports.
The PoE ports on the Catalyst Express 520 provide up to 15.4 W of power to
connected Cisco prestandard and IEEE 802.3af-compliant powered devices if the
switch detects that there is no power on the circuit. On a per-port basis, you can
control whether the PoE port automatically provides power when a powered device is
connected by using the Configuration Assistant. By default, the setting is Auto.
The back panel of the Cisco Unified IP phone might have more than one RJ-45 connector. Use
the LAN-to-phone connector to connect the phone to the UC 520. See the Unified IP Phones
7900 Series Install and Upgrade Guide
for your IP phone at

.
Step 2
For connecting to a fax: Connect an RJ-11 cable to one of the FXS ports on the front panel
of the UC 520. Connect the other end of the cable to a fax unit.
