Table 46 Troubleshooting the 4/256 SAN Director
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 4/256
SAN Director.
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 4/256 SAN Director 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.
