B: Upgrading System Firmware
Caution:
Consideration must be given to the firmware and the hardware version numbers of the XL-GPS and it’s optional
components. Consult with Symmetricom’s Customer Service department before performing upgrades.
This section explains how to completely upgrade the system firmware. This is done using the F100 BH,
F100 BUB, F100 BU, and F100 BF commands.
Overview of Procedure
•
Set up a network connection between your XL-GPS and the FTP server.
•
Set up an FTP Server with the firmware upgrade files.
•
Open a command line session to the XL-GPS.
•
Install the firmware version 8 files.
•
Reboot the XL-GPS.
Note:
If your system’s NTP and SNMP configuration files (ntp.conf, ntp.keys, snmp.conf) have been
customized, make backup copies and later re-install those configuration files. See
F100 Configuration” on page 114
.
Set up the FTP Server
To save time and trouble, download a preconfigured FTP server from
and extract it to the C:\ drive on your workstation. Otherwise, customize your existing FTP
server setup as described in this section.
When performing these operations, the user issues command line instructions to the XL-GPS. The XL-
GPS responds to those commands by connecting to the FTP server and burning the software to system
memory. The XL-GPS gives the FTP server ‘Anonymous’ as its user name, and uses a null password
(e.g., the equivalent of pressing the Enter key on your keyboard instead of entering text). The FTP
server must be configured as follows:
•
Anonymous log-ins are enabled
•
The password for Anonymous is disabled, or allows a null password
•
Anonymous has read/write privileges to Anonymous’s home directory.
Obtain the current system firmware files (E.g., 192-8001.bin, 192-8000.bt, 192-8002.fs) from
Symmetricom’s customer support website.
Place the system firmware upgrade files in home directory of the ‘anonymous’ user. If you’re using the
preconfigured FTP server, C:\Symmetricom is the default or home directory.
Open a Command Line Session on the XL-GPS
Note:
The XL-GPS and FTP server need to be connected by a TCP/IP network. Ideally they should be
on an isolated subnet. Connecting them over a network with multiple ‘hops’ or one with heavy
