Back panel
On the back panel, there are RJ-45 ports for connecting computers and other network devices

Device operation
1. Connect the power adapter (supplied) to the power connector on the side of the device
housing, then connect the power adapter to an electrical socket.
2. Connect the computers and other network devices to the RJ-45 connectors on the back

another switch (Uplink).
Half duplex and full duplex
PENTAGRAM NEsT 16P Compact supports half and full duplex modes in 10Base-T and 100Base-
TX modes.
Half duplex – data cannot be sent and received simultaneously. They are sent after the reception
has finished.
Full duplex – data can be sent and received simultaneously. This mode doubles the channel
bandwidth.
Full duplex transmission is possible:
• Between devices connected directly (e.g. switch–switch, switch–PC)
• When both devices support full duplex mode
• When both devices work in the same autonegotiation mode (e.g. autonegotiation–
autonegotiation, or no autonegotiation–no autonegotiation.)
Autonegotiation
Each device port has a link speed autonegotiation function. It allows to choose the best available
speed for each separate port during connection with other device.
The table represents the modes in which the switch will work after connection with various devices.
