CHAPTER 5: Operation
Take these steps:
1. C all Black Box Tech Support and follow their instructions to download the
necessary files for the upgrade onto the host PC. The model and version
numbers in the names of some of the files should all match each other, and
all of these files should be downloaded into the same directory:
– A universal upgrade installation/verification program, probably named
“SSDUO.EXE.”
– A data file that tells the program which firmware files to use for the
upgrade and where in the Duo’s/Quadro’s memory to put them.
Theoretically, this file can be modified so that only certain processors
inside the Duo/Quadro are upgraded, but
don’t try to do this
unless
specifically instructed to do so by Black Box Tech Support. There are five
varieties of this file—one for each model of the Duo and one for the
Quadro—which should be named “
u
X
c
V
xyz
.DAT”;
u
is the number of user
ports your switch has (2 for the Duo, 4 for the Quadro),
c
is the number of
CPU ports your switch has (4, 8, 12, or 16), and
xyz
is the
x.yz
firmware-
revision level. For example, “2X16V129.DAT” will be the data file for a
16-Port Duo for firmware version 1.29.
– The firmware files themselves. There are three of these, one for each of the
Duo’s/Quadro’s processors. Like the data file, each of these firmware files
comes in five varieties, one for each model of the Duo and one for the
Quadro. They should be named “
u
X
c
A
xyz
.HEX”, “
u
X
c
B
xyz
.HEX”, and
“
u
X
c
K
xyz
.HEX”; again,
u
is the number of user ports your switch has (2 for
the Duo, 4 for the Quadro),
c
is the number of CPU ports your switch has
(4, 8, 12, or 16), and
xyz
is the
x.yz
firmware-revision level. For example, to
upgrade an 8-Port Duo to hypothetical firmware version 1.32, you would
need the three files “2X8A132.HEX”, “2X8B132.HEX”, and
“2X8K132.HEX”.
2. Make sure that you’ve saved any important work on any computer CPUs
attached to the Duo/Quadro. The Duo/Quadro can be upgraded while
attached to live systems, although the mouse connections will probably need
to be restored after the upgrade is finished (see
Section 5.8
). Where possible,
however, mission-critical servers should be powered down or disconnected
before you continue with the upgrade.
