Installation Problems

By carefully following the installation procedures described in chapter 1,
"Installation", you can avoid most problems caused by improper installation
of the switch or one of its components.

Incorrect Hardware Installation

Incorrectly installing the switch or power cord can result in one or both of
these components malfunctioning or not functioning at all. If one or both of
these components appear not to be functioning, recheck the installation
procedure and, if necessary, reinstall the component correctly.
If the switch will not power on or intermittently resets itself, the switch's
processor may be faulty or the hardware/software setup may be wrong.

Console RS-232 Problems

If the switch powers on but the console interface will not start up, follow these
steps:
Check the external Console RS-232 connection. If you are not using a
modem connection, ensure that the cable is a null modem cable.
Check the console device settings against the settings listed in appendix
C, Sample Console Configurations.
Try a different baud rate setting in your console device. The switch's
default setting, "Speed Sense", automatically matches the Console RS-232
baud rate to the rate used by your PC, terminal, or modem. (However, if
the Baud Rate parameter in the switch's Serial Link screen has been
configured to a specific value, the Speed Sense operation is disabled.) The
switch operates at 300, 600, 1200, 2400, 4800, 9600, 19200, or 38400 bps.
If you are using a terminal emulation program, try exiting the program and
then restarting it.
If the diagnostic information does not appear, or is unintelligible, try changing
the baud rate on your terminal or PC terminal emulator. Try 9600 first. If the
problem continues, try each of the other rates listed above.
