B: Upgrading System Firmware
Caution:
Consideration must be given to the firmware and the hardware version numbers of the XLi and it’s optional com-
ponents. 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.
F100 BUB, F100 BU, and F100 BF commands.
Overview of Procedure
•
Set up a network connection between your XLi and the FTP server.
•
Set up an FTP Server with the firmware upgrade files.
•
Open a command line session to the XLi.
•
Install the firmware version 8 files.
•
Reboot the XLi.
Note:
If your system’s and SNMP configuration file (snmp.conf) has been customized, make a backup
copy and later re-install that configuration file. See
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 XLi. The XLi
responds to those commands by connecting to the FTP server and burning the software to system
memory. The XLi 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:

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:\TrueTime is the default or home directory.

Open a Command Line Session on the XLi
Note:
The XLi 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 network
traffic raises the possibility that the system software files could be corrupted, yielding the XLi
inoperable.
