Extended Function Commands Chapter 4: Serial or Telnet I/O Functions

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>/

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.
