Connect Interfaces
To connect a Cisco Unified 500 Series to a WAN, PSTN, and ISDN, perform the following 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 Cisco Unified 500 Series. 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 Cisco Unified 500 Series 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 Cisco Unified 500 Series and connect the other end of the cable to a PSTN line or a
station interface on a PBX.
Connect Devices
To connect wireless access points, Cisco Unified IP phones, and other devices to a Cisco Unified
500 Series or a Cisco Catalyst Express 520 switch, perform the following steps in any order:
Step 1 Install and connect Cisco Unified IP phones to the PoE ports on the front panel of the
Cisco Unified 500 Series and if installed, to PoE ports on front of the switch.
Note The PoE ports on the Cisco Unified 500 Series 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 Cisco 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 Cisco Unified 500 Series. See the
Unified IP Phones 7900 Series Install and Upgrade Guide for your IP phone at
