Installing firmware
The switch comes with current firmware installed. You can upgrade the firmware from the management
workstation as new firmware becomes available. You can use the McDATA Web Server application, the
McDATA Element Manager application, or the CLI to install new firmware.
You can load and activate firmware on an operating switch without disrupting data traffic or having to
re-initialize attached devices. If you attempt to perform a non-disruptive activation without satisfying the
following conditions, the switch will perform a disruptive activation:
• The current firmware version is a version that supports upgrading to the new version
• No changes are being made to switches in the fabric including powering up, powering down,
disconnecting or connecting ISLs, and switch configuration changes
• No port in the fabric is in the diagnostic state
• No zoning changes are being made in the fabric
• No changes are being made to attached devices including powering up, powering down,
disconnecting, connecting, and HBA configuration changes
Ports that are stable when the non-disruptive activation begins and then change states, will be reset. When
the non-disruptive activation is complete, McDATA Web Server or McDATA Element Manager sessions
reconnect automatically. However, Telnet sessions must be restarted manually.
