Ethernet Port
The back panel of the EDS8/16PS provides a network interface via the right most 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). Otherwise by default, the EDS8/16PS auto-negotiates the connection to the Ethernet
network.
LEDs
Light-emitting diodes (LEDs) on the front panel show status information.
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.

The reset button is on the rear of the device to the right of the Ethernet port, accessible through a
hole in the case. You can use it to reboot the unit or to reload factory defaults.
