Install Firmware

The switch comes with current firmware installed. You can upgrade the firmware from the management workstation as new firmware becomes available. Firmware installation involves loading the firmware image file onto the switch, unpacking the image file, and then resetting the switch to activate the new firmware.

Note: You can load and activate version 4.1 firmware on an operating switch without disrupting data traffic or having to re-initialize attached devices under the following conditions:

„The current firmware version is a 2.x, 3.x, or a 4.x version that precedes the upgrade 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.

Attempts to activate firmware before version 2.0 will be disruptive. Ports that are stable when the non-disruptive activation begins, then change states, will be reset. When the non-disruptive activation is complete, SANsurfer Switch Manager sessions reconnect automatically. However, Telnet sessions must be restarted manually.

You can use the SANsurfer Switch Manager application or the CLI to install new firmware:

„The SANsurfer Switch Manager application loads and unpacks the firmware image file in one operation. Refer to ”Using SANsurfer Switch Manager to Install Firmware” on page 4-20.

„When using the CLI on a workstation that has an FTP server, you can open a Telnet session and load and unpack the firmware image file using the CLI Image command. Refer to ”Using the CLI to Install Firmware” on page 4-20.

„When using the CLI on a workstation without an FTP server, you must open an FTP session through the switch to load the image file, then open a Telnet session to unpack it with the CLI Image command. Refer to ”Using FTP and the CLI to Install Firmware” on page 4-21.
