DHCP Setup
In many modern networks IP numbers are not static but are automatically assigned by a DHCP
server and can change over time or on each power up.
DHCP must be enabled on the Blue Heat/Net Sync because it is shipped to use a default static IP
(192.168.42.1)
Using SCM
Log onto the Blue Heat/Net Sync. The SCM does not require a login. The default password for
the SCM is password.
Enter net dhcp=yes. This will turn on DHCP on the unit.
Enter net dns_ip=3. This will set the DNS IP to 198.182.196.3
Enter save. This will save the configuration we just set to flash memory.
Enter exit. The unit will reboot using the new settings.

The Booter runs from flash memory first. Its job is to perform the following:
Setup the embedded processor
Validate at least one of the redundant Loaders (via a CRC check).
Load a validated Loader into RAM memory.
Run the Loader.
If the Booter discovers that both Loader programs are defective (erased or faulty CRC
calculation), an error code is displayed on the LEDs of the Blue Heat/Net Sync.
The Loader runs from RAM memory. Its job is to perform the following:
o Update any required CDS items.
o Determine if the SCM application will be entered. This is accomplished by
scanning the designated serial ports, for a period of time, to determine if a
correct password is entered. If the password is found the SCM application will
be entered. (see the
SCM Command Reference command for details of these
settings).
o Locate, load and run an Operating System (uClinux). (As shown in the
following boot-up flow chart).
o Run the main Operating System (uClinux).
