Methods of Assigning the IP Address

The unit's IP address must be configured before a network connection is available.
You have the following options for assigning an IP to your unit:
Method

DHCP

DeviceInstaller
ARP and Telnet
AutoIP
Serial Port Login
These methods are described in the remaining sections of this chapter.
Note:
administrator generally provides the IP address. Obtain the following
information before starting to set up your unit:
IP Address
Subnet Mask:
Gateway:
DHCP
The unit ships with a default IP address of 0.0.0.0, which automatically enables
DHCP.
Provided a DHCP server exists on the network, it will provide the unit with an IP
address, gateway address, and subnet mask when the unit boots up. The SDS2100
has acquired an IP address if the red LED stops flashing and the green Status LED is
on continuously. (If no DHCP server exists, the unit responds with a diagnostic error:
the red Diagnostic LED blinks continuously, and the green Status LED blinks five
times. This blinking only continues for about 15 seconds.)
You can use the DeviceInstaller software to search the network for the IP your unit
has been assigned by the DHCP server and add it to the managed list. See
Unit to the Manage List
Note: This DHCP address will not appear in the unit's standard configuration
screens. You can, however, determine your unit's DHCP-assigned IP
address in Monitor Mode. When you enter Monitor Mode from the serial port
with network connection enabled (see
chapter) and issue the NC (Network Communication) command, you will see
the unit's IP configuration.
Table 2-1. Methods of Assigning IP Addresses
Description
A DHCP server automatically assigns the IP address and network settings.
You manually assign the IP address using a graphical user interface (GUI).
You must use a PC and the unit must be attached to the local network.
You manually assign the IP address and other network settings at a
command prompt using a UNIX or Windows-based system. Only one person
at a time can be logged into the configuration port (port 9999). This eliminates
the possibility of several people simultaneously attempting to configure the
unit.
This automatic method is appropriate when you have a small group of hosts
rather than a large network. This method allows the hosts to negotiate with
each other and assign addresses, in effect creating a small network.
You initially configure the unit through a serial connection.
In most installations, a fixed IP address is desirable. The systems
