Managing the Software Image
The XSR can store more than one software image in Flash.
Creating Alternate Software Image Files
The XSR can create multiple software images, a useful option if you want to quickly select an
alternate image. For example, you can create two software image files:
XSR1805_a.fls and
xsr1805_b.fls.
Begin the process by issuing the
boot system command to create a boot-config file containing
the name of your software file. Enter:
boot system XSR1805_b.fls
The boot-config file contains the file name - XSR1805_a.fls - used by the autoboot process. By
changing the file name inside
boot-config, you will boot from the alternate software file in Flash,
XSR1805_b.fls:
BootRom Upgrade Choices
Upgrading from Version 2.xx to 3.xx code on the XSR 1800 Series
Because the XSR does not recognize the 3.x format, you cannot use the Bootrom Monitor Mode
commands
bu and bU to upgrade the Bootrom from version 2.x. You must upgrade from the CLI
using the following procedure:
1. With Bootrom version 2.x still installed, first upgrade the firmware image to Release 6.0 in the
usual manner by copying the
xsr1800.fls file to the Flash: directory and rebooting.
2. Copy Bootrom version 3.x to the
Flash: directory.
3. Enter the following command from the CLI:
bootrom update btXSR1800_3_x.fls where x is
the current sub-release number. The XSR will automatically reboot and be operable.
Upgrading from Version 1.xx to 2.xx code on the XSR 1800 Series
There are two methods available to upgrade your Bootrom. If you use the Bootrom Update Utility,
you will need the
updateBootrom.fls and bootromX_xx.fls files. For details on using these files
to perform a Bootrom upgrade, refer to “Using the Bootrom Update Utility” on page 2-30.
If not using the Bootrom Update Utility, you must perform a two-step procedure to upgrade from
1.xx to 2.xx Bootrom versions due to a file format change and will need the
bootrom_uncmp.fls
and
bootromX_xx1.fls files. For details, see “Local Bootrom Upgrade” on page 2-32.
Pre-upgrade Procedures
XSR firmware upgrades are infrequent but if you do so using Bootrom mode, you must:
• Make a DB-9 null modem serial link to a terminal (HyperTerminal, Procomm, et al.) with 9600
bps, 8 bits, 1 stop bit, and no flow control.
• Make an Ethernet connection at the first network interface (located next to the power switch).
• Connect to the FTP (default) or TFTP server on a host PC running with a known user and
password. Be sure you can access the latest Bootrom binary file on the host computer, e.g.,
bootrom1_21.fls.
Note: If the boot from Flash fails for any reason, the XSR will attempt to copy the specified software
file from the network based on the setting in Bootrom mode. Refer to the following section for details.
