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.
How the Blue Heat/Net Sync Boots Up
Each time the Blue Heat/Net Sync is powered-up or rebooted with an appropriate command, a
certain sequence of software execution occurs.
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).
