Connecting Your Phone to the Computer Network

Connecting Your Phone to the Wired Network

You connect your phone to the local network by using an Ethernet cable:

STEP 1 Plug the Ethernet cable into the back of the base station into the slot marked “SW.” This port is

labeled #4 on Figure 1 on page 23.

STEP 2 Plug the other end of the Ethernet cable into the appropriate device on your network, such as a

network switch.

NOTE The Cisco SPA 525G provides a second Ethernet port. You can connect a PC to this port to

provide network access to the PC. This port is labeled #3 in the Cisco SPA 525G IP Phone

Connections graphic. This port cannot be used when the phone is connected to the network via

the built-in Wireless-G client.

Connecting Your Phone to the Wireless Network

NOTE The PC port is not supported in wireless operation. The PC port is only supported in a wired

operation.

The Cisco SPA 525G phone supports a direct connection to the wireless network. Before

setting up the wireless network, you need to know the wireless security type for your router.

The Cisco SPA 525G works with the following security types:

• WEP—Wired Equivalent Privacy. With this type of security, you need to enter a 64 or

128-bit key on the phone (or a more easily remembered passphrase to generate the

key). The phone then authenticates with your router to provide a secure connection.

• WPA—Wi-Fi Protected Access. The Cisco SPA 525G supports WPA PSK, WPA2

PSK, WPA Enterprise, and WPA2 Enterprise. With this type of security, you will at the

very minimum be required to enter a password on the phone. The phone then

authenticates with your router to provide a secure connection.

Determining Your Wireless Router Security Type

If you do not know your wireless router security type, you need to log in to the router interface

to get this information. The steps below are written for a Linksys router, but procedures for

other routers should be similar.
