How to connect an IP Phone
Direct Connection to a PoE Switch in ICT management (preferred setup)

The IP phone (3) is connected via a network UTP patch cable (2) to a wall socket (1), which is linked to an ICT-managed PoE switch (6). This switch provides both power and data connectivity. A computer (4) is connected to the port labelled "PC" on the IP phone (3) using a UTP cable (2).
Connecting directly to the switch (without PoE support) in ICT management

The IP phone (3) is connected via UTP cable (2) to a wall socket (1) linked to an ICT-managed switch (6) without PoE support providing data connection. In this case, the phone (3) requires an external power adapter (7). A computer (4) is connected to the phone's "PC" port using another UTP cable (2).
Connecting directly to a switch in ICT management with multiple computers

The IP phone (3) is connected to a wall socket (1) via a UTP network cable (2), which is in turn connected to an ICT switch (6). This switch may provide both data and power connectivity. Multiple computers (4) in the room are connected through a small unmanaged switch (8), which in turn is connected to the phone's "PC" port.
Connecting directly to a switch in ICT management with multiple computers and multiple phones

Such a connection is only allowed when a direct connection of the IP phone to the ICT switch is not possible. The first IP phone (3 – left) connects to the wall socket (1) via UTP cable (2), which leads to the ICT switch (6) providing either data or power connectivity. The second IP phone (3 – right) connects from its "SW" port to the "PC" port of the first phone. On the second phone, you must manually configure the VOICE VLAN setting. The second phone requires an external power adapter (7). Multiple computers (4) are connected via network UTP cable (2) to an unmanaged switch (8), which is connected to the second phone's "PC" port.
