B: Upgrading System Firmware

Consideration must be given to the firmware and the hardware version numbers of the XLi and it's
optional components. Consult with Symmetricom's Customer Service department before performing
upgrades. See "H: Sales and Customer Assistance", page 295
This section explains how to completely upgrade the system firmware. This is done using the F100 BH,
F100 BUB, F100 BU, F100 BF and F100 BUFP 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 files with versions recommended by Symmetricom Customer Service.
• Reboot the XLi.
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

Set up the FTP Server

To save time and trouble, download a preconfigured FTP server from
warftpd1.zip 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:
• 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:\ is the default or home directory.
The XLi Web Browser can be used to upgrade the system firmware and is the recommended method.
