Firmware
download
There are multiple phases to firmware download and activation. When Web Tools reports that
firmware download 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 restart is required to activate the newly downloaded firmware. This restart is done
automatically; however, although Web Tools windows continue to display during the restart,
they are not available. Wait approximately 10 minutes to ensure that all of the application
windows are 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 restart (initiated through the
firmwareDownload ) varies for different configurations:
Brocade DCX and DCX-4S enterprise-class platforms: 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.
Brocade 300, 5100, 5300, 6510, 6520, 7800, 7840, VA-40FC, and the Encryption Switch:
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.
Firmware
downgrade
If you try to run Web Tools on a switch after downgrading the firmware, Web Tools may not
open. This is due to the presence of old application cache files in Java. The workaround is to
delete the application cache files using the Java Control Panel.
After upgrading or downgrading the firmware, delete the application cache files.
HTTP timeout
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 reports 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.
In-band
management
support
Fabric OS v7.3.0 supports Web Tools, SNMP polling, and SNMP traps only in IPv4 on the
Brocade 7800 and FX8-24.
Java cache
If the Web Tools progress bar stops at 93 percent when initializing switch details, you must
clear the Java cache, as described in
Deleting temporary Internet files used by Java
