A Troubleshooting

Appendix A

Introduction

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

Hardware Problems

If the Device Server Power/Ready LED is red and stays red for over 10 seconds, you have a hardware problem that is going to require factory service. If you purchased the Device Server 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 done on a Device Server that has not been registered.

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 27 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 Device Server, reboot the Device Server (does not apply when using BOOTP or DHCP). Once the Device Server 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?

zIf the WebManager or DeviceManager cannot communicate with the Device Server, verify that the Server Services HTTP is enabled for WebManager and DeviceManagerD is enabled for DeviceManager.
