Important Note:
4.4.15 F100 J - Jumper
Use F100 PT to display the state of jumper JP5, which is reserved for future use. This
function also displays the security flag bits and disable bits.
To display the state of jumper J5, send the following command:
F100 J<Enter>
An example unit response:
Jumper JP5 = 0
Security flags = 0x00000000
FPC_SECURITY_BIT = 0
BURN_DISABLE_BIT = 0
UNIT_REMOTE_DISABLE_BIT = 0
PASSWORD_SETTING_DISABLE_BIT = 0
JP5 is located near the middle of the printed circuit board, beside the two flashing LEDs
and the NetARM microprocessor.
4.4.16 F100 BH - Burn Host
Use Burn Host when upgrading software, to select the FTP host and the file to be
transferred.
To select the FTP host and file for upgrading, send the following command:
F100 BH <FTP host IP address><SP><Upgrade file path>/
<file name><Enter>
For example:
F100 BH 10.1.7.20 Lassen/Rel/REL20010518/nts200/192-9004v001.BIN
The unit responds:
Burn host is ready
This command can be disabled by the Burn Host Lock command, which denies serial and
Telnet access. However, if you enter BootLoader mode, this command is always available.
4.4.17 F100 BU - Burn
Use Burn when upgrading software, to write the file selected with F100 BH to the flash
memory. Flash memory is checked to ensure that the correct file is used.
The following commands related to sofware upgrades (F100 J, BH, BU, BUB, BF and K I L L)
are not the normal commands used for uploading firmware. Symmetricom provides these
commands for flexibility in supporting special case situations. Normal firmware upgrades use
an easy-to-use upgrade program provided with the firmware.
Use UNIX style forward slashes ‘/’ in path and do not describe the drive (for example, ‘C’) in
the path.
