Introduction

This chapter provides information that can help resolve problems with the IOLAN.

Hardware Problems

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:

zIf the IOLAN is not in Console mode, do the following:

a.Set up a direct connection to the IOLAN; see Through the Serial Port on page 38 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.

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/serial.shtml.

zIf the IOLAN is already in Console mode and the Power LED stays red, 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.

Power/Ready LED continues to flash green in Desktop models

This is not an error, the Power/Ready LED will flahs green when serial port 1 is in Console Mode.

Communication Issues

General communication checks and practices are as follows:

zAre your cables connected and correctly configured? If you are using EIA-232, see EIA-232 Cabling Diagrams on page 191 to verify that your cables are correctly configured.

zPing your host? If you can ping but packet loss is reported, ping another host/device on the same network. This will tell you whether the problem is specific to the host/device or general to the network.

zAfter entering or changing IP information for your IOLAN, reboot the IOLAN (does not apply when using BOOTP or DHCP). Once the IOLAN has rebooted, other network devices should be able to communicate with it (ping, telnet, etc.). Also, protocols such as ARP and proxy-ARP will work properly.

zUse the show routes command (command line only) or view the Routes statistics. Is there a route to the host?
