C H A P T E R 7 Console Port Use and Troubleshooting Use of the Console Port Purpose of Console Port Local Management Maintenance Mode Switch Software Restoring Software If you lose contact with the switch and the Recovery Manager in Intel Device View or Local Management over the LAN cannot contact it, then the following is possible via the Console port on the front of the switch. During normal operation (the switch is running and the Status LED is green) the Console port will give access to a menu, identical to the one accessible via a telnet connection to the switch. The menu allows configuration of basic parameters, extensive monitoring, flash operations, reset of the switch etc. If the switch is failing for some reason (System LED goes red), and cannot start correctly after a reset, this may be caused by either hardware failure, corruption of the software, or corruption of the switch configuration. To allow recovery from such a situation when the Recovery Manager of Intel Device View cannot be applied, the maintenance mode is provided. In the following, various problems are described as well as the way they are solved using maintenance mode. In the next section it is explained how to start and use the maintenance mode. Note Loading software to the switch in Maintenance Mode should only be done as a last resort, the reason being that the software and configuration are already resident in the flash memory is overwritten and lost. The software for the switch (including a default configuration) resides in the switch's flash memory. A backup of the software is provided on the CD delivered with the switch, and the newest software versions may be downloaded via the Internet. The software files may be used for restoring or upgrading the switch software. The switch software may be restored/downloaded from a TFTP server, if the current software in flash memory has been corrupted. The TFTP and BOOTP commands may both be used to accomplish this. For the TFTP command an external TFTP server with the software must be present on the network. For the BOOTP command a BOOTP/ TFTP server (also often referred to as a boot server) must be present. 106
