Typical Installation
To install a Cisco Secure Router 520 ADSL-over-POTS router, follow these steps:
Step 1 If you have a wireless router, first connect the radio antenna to the router. See the “Connecting a Radio
Antenna to a Wireless Router” section on page 3-1.
Step 2 Connect the server, PC, or workstation to the router. See the “Connecting a Server, PC, or Workstation”
section on page 4-6.
Step 3 (Optional) If you need to connect more than four PCs, connect an external Ethernet switch to the router’s
built-in switch. See the
“Connecting an External Ethernet Switch (Optional)” section on page 4-7.
Step 4 Connect the ADSL line. See the “Connecting an ADSL Line—ADSLoPOTS Port” section on page 4-9.
Step 5 Connect the AC adapter to the router. See the “Connecting the AC Adapter” section on page 4-12.
Step 6 To configure the router software by using the command-line interface (CLI) or to troubleshoot problems,
connect a terminal or PC to the console port. See the
“Connecting a Terminal or PC to the Console Port”
section on page 4-14.
Step 7 (Optional) To use the console port as a backup link to the WAN port in case the ADSL service goes down,
connect an analog modem to the console port. See the
“Connecting an Asynchronous Modem to the
Console Port” section on page 4-14.
