Guralp Systems CMG-DCM build <10,000 - Manual (Page 18)

CMG-EAM (Platinum Firmware)
can access the CMG-EAM over a network, you must set (for static
addresses) or discover (if you use DHCP) its IP address.
2.2.1 DHCP-assigned addresses
If your network uses DHCP to assign addresses, connect the CMG-EAM
to the network and reboot it by turning the power off and on again
Your network administrator may then be able to tell you the address
that has been assigned to the CMG-EAM but, if not, you can connect
via a serial port and issue the ip command:
eam999 ~ # ip addr show eth0
2: eth0: mtu 1500 qdisc
pfifo_fast qlen 1000
link/ether 00:50:c2:40:54:75 brd ff:ff:ff:ff:ff:ff
inet 192.168.0.101/24 brd 192.168.1.255 scope global eth0
inet6 fe80::250:c2ff:fe40:5475/64 scope link
valid_lft forever preferred_lft forever
eam999 ~ #
The key things to look for here are the adapter status and the IP
address. The first line of the output should contain the word UP,
confirming that the adaptor has been enabled. The IP address that has
been assigned is shown on the line beginning inet - in this case, it is
192.168.0.101 (with a netmask of 24-bits indicated by /24).
When using DHCP, it is recommended that the DHCP administrator
allocates a fixed IP address to the CMG-EAM's MAC address in order to
avoid unexpected address changes.

Note: With an IP version 6 network, the IP address will be on a
line beginning inet6. In practice, most networks today are still
IPv4, as in the above example.
Note: If you are setting up a unit in the laboratory for
subsequent deployment in the field, you can set up the final
network address using the web interface and over-ride it with a
temporary, static network address using the command line.
The web-configured address will take effect when the unit is
next rebooted.
