You may have a router or switch to which you connect the phone. Whatever connectivity exists
between the phone and the SIP server, ensure that you use the LAN port to perform the uplink.

Connect your PC or notebook to any of the other three circuits (P1, P2, or P3). You can identify if
the phone has connectivity and activity on any of the circuits as described in section 9.4.3 on page
117.
4.1.4.3 Cascading
The ZIP4x4 has a very efficient network switch incorporated in it so you can cascade the phones
as shown in figure 4-2.
Connect the LAN port on the phone to the LAN and connect other phones to the other ports.
Connect your PC to the fourth port. You can use any of the ports P1, P2, and P3 for the other
phones or your PC.
At the second phone in the chain, connect the LAN port to the first phone in the chain. The first
phone can obtain power from the LAN through the first phone. The ZIP4x4 does not propagate
the power to any of the ports P1, P2, or P3. Therefore, a phone connected to one of these ports
must obtain its power from an ac adapter.
Although you can continue to cascade phones in this manner, it is not recommended that you do
so. The network may be difficult to manage and may have poor performance.
Once you have made the connections, you can identify if a phone has connectivity and activity
on any of its circuits as described in section 9.4.3 on page 117.

1. If you do not use VLANs on the phone, and if you do not expect the phone to receive power from the network, you can
actually use any port to connect to the phone system. In this case, the switch inside the ZIP4x4 is an unmanaged switch
and it does not matter to which port you connect. However, the phone must have connectivity on the port marked LAN
and always using this to connect to the network ensures that you have a consistent network that is easier to maintain.
