Utilizing the Command Line Interface
2-30 Managing the XSR
• Optionally, if you have CompactFlash installed, you can download the firmware file to
cflash: then perform Step 1 (see below) followed by the bu (lower-case u ) command.
• If you use the Cabletron TFTP/BOOTP Services application, which does not recognize long
file names, first shorten the Bootrom file name to 8 characters or less with an extension, before
beginning the download (i.e.:
bootnew.fls ). Rename the file after the download.
• Be aware that factory default Flash is limited to 8 Mbytes and if congested may not be able to
store a downloaded Bootrom. Delete old firmware or other files before downloading.
Using the Bootrom Update Utility
The Bootrom update utility upgrades the boot flash sectors of the on-board Flash memory. This
update tool functions similar to the
bU command but also can be executed from a Telnet session,
allowing Bootrom updates to be performed remotely. The utility runs as a standalone program
and can recognize both old (1.x) and new (2.01) versions of the Bootrom file format. After you
complete the Bootrom update, the XSR will reboot.
Note that screen-captured XSR text is displayed in Courier font. User-required input appears in
larger, bold Courier font.
1. From a remote Telnet session, at a CLI prompt, configure the “boot-config” file to your current
software file residing in flash: (the default is
xsr1800.fls ; if your Bootrom version is earlier
than 1.16, the default is xsr1805.fls ). Enter:
XSR(config)# boot system xsr1800.fls
xsr1800.fls saved into flash:boot-config
2. Exit to EXEC mode and verify this setting by entering:
more boot-config
. Verify at least two
MBytes of flash file space is open by entering the dir command. If file space is low, delete
unnecessary files. The following files are required ( xsr1800.fls may be replaced by the
current software file):
XSR-1805# dir
Listing Directory flash:/
size date time name

3. Using TFTP, transfer the latest Bootrom version from the network. The target name must be
bootrom.fls:
–
XSR-1805#copy tftp://192.168.27.95/C:/tftpDir/ bootrom2_01.fls
flash:bootrom.fls
– Copy 'tftpDir/bootrom2_01.fls' from server as 'bootrom.fls' into
Flash(y/n) ? y
