Ethernet Port
The back panel of the EDS8/16PS provides a network interface via the rightmost
RJ45 port. This port can connect to an Ethernet (10 Mbps) or Fast Ethernet (100
Mbps) network. The Speed LED on the back of the EDS8/16PS shows the
connection of the attached Ethernet network. The EDS8/16PS can be configured to
operate at a fixed Ethernet speed and duplex mode (half- or full-duplex) or to auto-
negotiate the connection to the Ethernet network.

Each serial port plus the console port have a Transmit and a Receive LED.
The Ethernet port has Speed, Activity, Power, and Status LEDs.
The table below describes the LEDs on the front of the EDSPS.
