Upgrading Firmware using TFTP

12.Confirm the TFTP download by entering y or yes and pressing the Enter key.

13.The IP Console Switch verifies the download. Enter y or yes to confirm the upgrade, then press the Enter key.

14.The IP Console Switch begins the FLASH upgrade process. On-screen indicators display the upgrade process. When the upload is complete, the IP Console Switch resets and upgrades the internal subsystems. This process takes a few minutes.

When the upgrade is complete, the startup message from step 4 is displayed in the IP Viewer HyperTerminal dialog box.

CAUTION: Do not cycle power to the IP Console Switch during this process. A loss of power might render the IP Console Switch inoperable and require that the unit be returned to the factory for repair. Be patient; the update can take as long as 10 minutes.

15.Click X to exit the IPViewer Hyper Terminal window.Analyzing FLASH Failures

At times a FLASH update fails. Unlike the IP Console Switch, which returns a failure message when it encounters any problems, a FLASH update failure gives no direct indications that a failure occurred.

When a failure occurs, you must verify several aspects of the update:

•Be sure that TFTP is configured properly. TFTP is an unreliable transport mechanism. A busy network can result in lost packets, which would cause the update to fail.

•Be sure that the tftpd log file /var/log/secure is secure. The log indicates if a successful tftpd connection was made and if any abnormal operations occurred.

•Be sure that the proper pathname to the image file is used.
