ES3000 Advanced Concept Guide
2-2
2.1 Initial Communication with the Switch
The ES3000 Layer 2 Ethernet switch uses three means of communication for administration of the
switch: serial communication via the DB-9 cable on the front of the system, telnet communication
over the network, and http communication over the network. Almost all configuration can be done
using any of these means of communication. However, bootcode reconfiguration requires that the
administrator be using serial communication.
The only purpose of the IP address for the switch is to facilitate communication with the switch. The
ES3000 switch defaults to DHCP for its IP address. If an installation requires that the switch have a
fixed IP address, the IP address should be set using the serial interface.
The serial communication parameters of the ES3000 switch are 19200 baud, 8 bits, no parity, one stop
bit, hardware flow control, and VT100 emulation. The ES3000 has a male DB-9 connector.
2.2 Setting The Switch IP Address
To set the IP address using the serial communication system, allow the ES3000 to boot. After some
self-test messages, the ES3000 will display a login prompt:
