Troubleshooting the switch

Issue
Entire chassis powers off
automatically.
Several or all components
are not operating.
Serial connection is faulty
or serial port logs have
incorrect or missing
information.
82 Operating the switch
Possible cause
Power supplies are inadequate to
support the installed components.
One or both power cables may
not be connected to a live source.
One or both AC power switches
might be off.
Serial cable is not connected
correctly.
Terminal emulator application
parameters are not set correctly.
Serial port might be incompatible
(only RS-232 is supported).
Pins on the serial cable or serial
port might be damaged.
Recommended action
Add an additional power supply.
Ensure that both power cables are
connected to live outlets.
Ensure that both AC power
switches are on (AC switches light
up green when on).
Ensure that the cable is firmly
connected to workstation computer
and to the switch.
Ensure that the terminal emulator
application is configured as
follows: 9600 bits per second, 8
databits, no parity, 1 stop bit, no
flow control.
Ensure that the switch is connected
to an RS-232 port. RS-423 serial
ports might experience difficulties
due to corner-case incompatibilities
of the standards.
Remove the cable and inspect the
pins on the cable and in the serial
port. Do not reinstall if the pins on
either component have any visible
damage, as this could damage the
pins on the other component.
Replace components as required.
