One or both AC power switches might be off. Ensure that both AC power switches are on (AC switches light up green when on). Serial connection is faulty or serial port logs have incorrect or missing information. Serial cable is not connected correctly. Terminal emulator application parameters are not set correctly. 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. Serial port might be incompatible (only RS-232 is supported). 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. Pins on the serial cable or serial port might be damaged. 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. 82 Operating the switch

Table 15
Troubleshooting the switch
Issue
Possible cause
Recommended action
Entire chassis powers off
automatically.
Power supplies are inadequate to
support the installed components.
Add an additional power supply.
Several or all components
are not operating.
One or both power cables may
not be connected to a live source.
Ensure that both power cables are
connected to live outlets.
One or both AC power switches
might be off.
Ensure that both AC power
switches are on (AC switches light
up green when on).
Serial connection is faulty
or serial port logs have
incorrect or missing
information.
Serial cable is not connected
correctly.
Ensure that the cable is firmly
connected to workstation computer
and to the switch.
Terminal emulator application
parameters are not set correctly.
Ensure that the terminal emulator
application is configured as
follows: 9600 bits per second, 8
databits, no parity, 1 stop bit, no
flow control.
Serial port might be incompatible
(only RS-232 is supported).
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.
Pins on the serial cable or serial
port might be damaged.
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.
