SERVSWITCH™ DUO AND SERVSWITCH™ QUADRO
5.20 Upgrading the Duo’s/Quadro’s Firmware
Because the ServSwitch Duo/Quadro stores most of its firmware (its “operating
system,” if you will) in flash memory, the firmware is upgradable. To fix bugs in
existing firmware, or to add new features to your Duo/Quadro, Black Box
Technical Support might sometimes recommend that you upgrade the Duo’s/
Quadro’s firmware if a newer revision is available.
You can check which version of firmware a Duo/Quadro is currently running by
looking at its onscreen menu. Activate the menu by pressing {hotkeys} + [M] (see
Section 5.11
), then press [F1]. The version number of the Duo’s/Quadro’s current
firmware will be displayed at the bottom of the Configuration Menu.
To upgrade the Duo’s/Quadro’s firmware, you’ll need a “host PC,” which must
be an IBM PC compatible computer with an RS-232 serial port. This computer
must be running an operating system that can execute DOS programs, such as MS-
DOS
®
or Windows
®
3.x, 95, 98, or 2000. You’ll also need a standard straight-
through-pinned DB9 female to DB9 male RS-232 serial extension cable to transfer
the firmware files to the Duo/Quadro. One of these cables is included with the
Duo/Quadro; if it’s been misplaced or broken, replacements are available
separately as product code EDN12H-MF (specify length).
NOTE
The programs used to upgrade the firmware of the Duo/Quadro are
DOS-based for the maximum range of OS compatibility. They run quite
efficiently under DOS, Windows 3.x, Windows for Workgroups,
Windows 95 or 98, Windows Me
®
, and even Windows NT
®
, taking roughly
10 minutes to complete the upgrade. But when these programs are run
under Windows 2000 or Windows XP
®
, which don’t handle DOS
programs well, they can take substantially longer. Upgrades will be
reliable but might require three or more hours to complete. For this
reason we recommend that you run the upgrade programs on a
computer using an older version of Windows.
