BootRom Upgrade Choices
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 more information on how to use these files to
perform your Bootrom upgrade, refer to the Using the Bootrom Update
Utility section.
If you do not use the Bootrom Update Utility, you must perform a two-step
procedure to upgrade from 1.xx to 2.xx Bootrom versions due to a change in
file format. To do so, you will need the
bootrom_uncmp.fls and
bootromX_xx1.fls files. For more information on how to use these files to
perform your Bootrom upgrade, refer to the Local Bootrom Upgrade section.
Pre-upgrade Procedures
XSR firmware upgrades are infrequent but if you do so using Bootrom mode,
you must perform the following:
 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.
 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 memory is limited to 8 Mbytes
and if congested may not be able to store a downloaded Bootrom.
Remove old firmware or other files before downloading.
