Troubleshooting
No power. a. Check power cord.
b. Make sure power switch is turned ON.
c. Check cable connection from PC to MasterConsole II.
No video display for one
or all computers.
a. Check video cable’s connection to the PC.
b. Check the monitor and PC: Turn off power to
MasterConsole and the PCs. Connect the monitor to
the PC directly, boot the PC, and make sure the
monitor has the proper display. If it does not, the
problem is either with your PC, or the monitor is not
compatible with your PC. If it does display, continue
to Troubleshooting #3.
The monitor cannot
correctly display the video
output from some of the
PCs.
a. The monitor probably does not match the video
outputs. If the monitor is a single mode type VGA, all
PCs must have the same type of video output.
b. (Note: this problem occurs most often with some IBM
PS/2s and IBM 63xx, 85xx, and 95xx monitors.) The
intelligent type display card outputs video signals
based on the monitor ID-pin setting in the connector
of the monitor cable. If the ID-pin setting is correct,
the monitor at MasterConsole may have no display,
become monochrome instead of color, or become
unstable. If this is the case, you will need to provide a
proper ID-pattern to the display card. Call Raritan
Computer for help if necessary.
All PCs powered up
without keyboard error,
but the keyboard at
MasterConsole II has no
control (cannot input to
any PC).
a. Make sure the keyboard is connected firmly into
MasterConsole II. Disconnect and reconnect
keyboard.
b. Replace keyboard. (MasterConsole II allows hot re-
connection of keyboard at its Keyboard port.)
c. In a two-tier configuration, check that the
MasterConsole II with the keyboard connected is the
base unit.
Repeat “KB ERROR” at
power-up of PC.
a. The keyboard cable from the PC to MasterConsole II
is loose. Secure the connection and power up the PC
again
b. If the problem occurs after MasterConsole II has
been installed for a period of time, and occurs on PCs
that have previously worked with MasterConsole II ,
then some components are out of order. Verif
