Saving and Implementing Changes
When you change a configuration parameter through the front-panel operator interface, the
change is not implemented until it is saved and the OM 1000 is rebooted. Use the following
method to save your configuration changes:
1
Select
ADMIN
on the MAIN menu (Figure 4-2), and then press
ENT
to display the
Administrative menu.
2
Select
SAVE
on the Administrative menu (Figure 4-3), and then press
ENT
.
3
Press . When the unit displays OK, press
ENT
to store the changes to flash memory.
CAUTION!
If the BOOTP server is on the local network, any configuration changes made from the front panel are overwritten by
the default parameters in the dynamic configuration file after a reboot or a power cycle if the configuration file is forced
to be downloaded from the BOOTP server.

Rebooting the OM 1000
Use the following procedure to reboot your OM 1000:
1
Select
ADMIN
on the MAIN menu (Figure 4-2) and then press
ENT
to display the
Administrative menu.
2
Select
REBOOT
on the Administrative menu (Figure 4-3), and then press
ENT
.
3
Press . When the unit displays OK, press
ENT
to reboot the OM 1000.
The boot process has three phases:
Power-on self-test
Mini-boot
Application load and execute
The power-on self-test is an internal RAM test and executes only during a power-on cold boot.
The OM 1000 will not perform this test during a reboot from the front panel.
The OM 1000 initializes boot file systems during the mini-boot phase. The boot program copies
the initialization files from flash memory to a RAM disk. After the boot program stores the
initialization files on the RAM disk, the unit broadcasts BOOTP requests over the Ethernet for
up to 10 seconds.
If the OM 1000 receives a response from the server, a new boot file transfers to the OM 1000
through the Ethernet. The information in the BOOTP response includes the unit IP address and
subnet mask, the IP address of the host server, and the full path name of the boot file. The
OM 1000 compares the filenames in the boot file to the files stored in internal memory. If a
filename is different than the internally stored data, the unit replaces the stored boot file with
the boot file from the server. If a response is not received, operation and configuration data
stored in internal memory controls the OM 1000 until a power-down or until the configurations
are changed at the front panel.
