This chapter provides information that can help resolve problems with the IOLAN.
Hardware Troubleshooting
The Power/Ready LED stays red after a boot.
If the IOLAN Power/Ready LED is red and stays red for over 10 seconds, you have a hardware
problem that might to require factory service. First, try the following:
z
In Console mode for desktop models or viewing the Console port in rack mount models, see if
you need to reload the firmware, which can be found either on the CD-ROM that came with the
IOLAN or on the Perle website,
.
z
If the bootloader option does not appear when you reboot the IOLAN (to load new firmware),
you need to make arrangements to return the IOLAN.
If you purchased the IOLAN less than 30 days before this problem appears, contact your distributor;
otherwise, see the Perle web site (
www.Perle.com
) for factory service information. Note: no factory
service can be performed on IOLANs that have not been registered.
The Power/Ready LED on a rack mount model flashes red:
z
Good Boot: When the IOLAN cycles through a good boot, the Power/Ready LED cycles for
several seconds and then stays a solid green.
z
Noncritical Error Boot: When the IOLAN cycles through a boot and a noncritical error occurs,
such as a bad port, the Power/Ready LED will flash red briefly before displaying a solid green.
You should reboot the IOLAN while monitoring the Console port to view the error information.
z
Critical Error Boot: When the IOLAN cycles through a boot and a critical error occurs, such as
corrupted firmware, the Power/Ready LED continues to flash red. View the IOLAN reboot
through the Console port for information on how to correct the problem.
z
Fatal Error Boot: When the IOLAN cycles through a boot and a fatal error occurs, the
Power/Ready LED stays a solid red).
