Introduction
This chapter provides information that can help resolve problems with the IOLAN.
Hardware Troubleshooting
The Power/Ready LED stays red after a boot (See Getting to Know Your IOLAN for the LED
label on your IOLAN unit.):
If the IOLAN Power/Ready LED is red and stays red for over 10 seconds, you have a hardware
problem that might require factory service. First, try the following:
z If the IOLAN is not in Console mode, do the following:
a. Set up a direct connection to the IOLAN; see Console/Serial Switch for information on this
type of connection.
b. Power the IOLAN off.
c. Switch the Console dip switch to On.
d. Power the IOLAN on.
e. Read the messages on the console to determine if the problem can be fixed.
If there is a problem with the IOLAN firmware, you will need to reload the firmware, which can
be found either on the CD-ROM that came with the IOLAN or on the Perle website,
www.perle.com/downloads (when you access the webpage, select your specific IOLAN
model).
z If the IOLAN is already in Console mode and the Power LED stays red, you need to make
arrangements to return the IOLAN.
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,
www.perle.com/downloads (when you access the webpage,
select your specific IOLAN model).
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.
The Power/Ready LED blinks red (See Communication Issues for the LED label on your
IOLAN unit.):
z Good Boot: When the IOLAN cycles through a good boot, the LED blinks for several seconds
and then stays a solid green.
Note:
No factory service can be performed on IOLANs that have not been registered.
