Setup IP
This section describes the connectivity procedure for the SierraNet M168 System (see “IP
Settings...” on page 24 ).
Configuring the Ethernet Connection
There are two ways of configuring a SierraNet M168 for network connectivity:
 DHCP automatically assigns an IP address. DHCP is the default.
 Static IP prompts you to enter a specific IP address.
The SierraNet M168 can be configured from the unit itself using the five buttons and the
LCD display on the front panel of the analyzer. For additional information, see
“LCD
Display and Button Functions for Configuring the Analyzer” on page 12 .
Dynamic Configurations
Dynamic configuration uses DHCP (Dynamic Host Configuration Protocol).
Under DHCP, SierraNet M168 will issue a broadcast to any DHCP Server requesting
configuration. If a DHCP server is present on the network, it will assign an IP address,
Subnet Mask and a default GATEWAY (a router port IP address) to the SierraNet M168.
The Gateway port will be used by SierraNet M168 to forward packets to IP addresses that
do not reside within the same subnet.
When using the dynamic configuration, the front panel display will only update the IP
address.
The subnet mask and gateway address will remain at the last values programmed
(000.000.000.000 by default, or whatever was last programmed in the static
configuration). While in dynamic mode, these parameters will have actually been
programmed within the IP STACK inside the SierraNet M168, but are not displayed in the
LCD display.
To change from DHCP to Static IP, you must be connected to a device using USB:
1. Select Setup > All Connected Devices > IP Settings from the menu bar.
Note: If you are connected to the device using Ethernet, the Configuration menu does not have the
Setup IP command.
The IP Setting dialog displays. For IP Mode, two radio buttons are available: 
Static IP and DHCP. DHCP is the default (see
Figure 1.21 on page 29 .)
