19 Table 19-1 Web Tools Limitations (Continued) Area Details Firmware download There are multiple phases to firmware download and activation. When Web Tools reports that firmware download has completed successfully, this indicates that a basic sanity check, package retrieval, package unloading, and verification was successful. Web Tools forces a full package install. A reboot is required to activate the newly downloaded firmware. This reboot is done automatically; however, although Web Tools screens will continue to be visible during the reboot, they will not be available. Wait approximately 10 minutes to ensure that all of the application windows have been restored. If Web Tools fails to respond after 20 minutes, you might need to close all Web Tools applications windows and restart them, or to contact your system administrator for network assistance. The Web Tools loss of network connectivity during a failover or reboot (initiated though the firmwareDownload) varies for different configurations: • SilkWorm 24000 and 48000 directors: loss of network connectivity is up to 5 minutes if the power-on self-test (POST) is disabled. If POST is enabled, the loss of network connectivity can exceed 5 minutes. • SilkWorm 200E, 3250, 3850, 3900, 4100, 4900, and 7500 switches: loss of network connectivity is up to 1 minute if POST is disabled. If POST is enabled, the loss of network connectivity can exceed 1 minute. HTTP timeout Very occasionally, you might see the following message when you try to get data from a switch or to send a request to the switch: Failed to get switch response. Please verify the status of your last operation and try again if necessary. This indicates that an HTTP request did not get a response. The request was sent to the switch, but the connection was down, probably caused by a temporary loss of the Web server on the switch. Due to the nature of an HTTP connection, Web Tools will report this error after a 90-second default timeout. In this case, verify the status of your last request, using telnet to check related status, or click the Refresh button from the Web Tools application you were working on to retrieve related data. If your request did not get through to the switch, resubmit it. Executing a refresh from Web Tools retrieves a copy of switch data at that moment; the data you entered can be lost if it had not already committed to the switch. Java Plug-in If you remove the certificate (not recommended) from the Java Control Panel, you must close and reopen the browser for the certificate removal to take effect. 19-2 Web Tools Administrator's Guide Publication Number: 53-0000194-01
