Upgrading Device Firmware

Use the Upgrade Device window to load a new, or reinstall the current, flash image to the line card.

 

Upgrading or Reinstalling Software

An upgrade replaces the current version of software with a newer version. A reinstallation reloads the line card with a copy of the current version of the software. The source software you use for an upgrade or reinstallation must be stored on a network host or server.

The line card uses TFTP (Trivial File Transfer Protocol) to download the installation image file.

Procedure:

Step Action
1 Check that the information is correct in the Image Filename and TFTP server settings input boxes.

To change the displayed information, double-click the text you want to change and enter new information.

2 Click Apply to start the upgrade operation or click Restore Form to return the settings to the last ones used.
3 After the upgrade procedure completes, use the CLI to update the software version in configuration memory (not needed for reinstallation). Refer to your release notes for instructions.

Interpreting LEDs During Upgrades

Refer to page 5 of the DIGITAL GIGAswitch GS2000 Line Card Installation manual for a description of the LED behavior during upgrades.

Field Descriptions

Status of Last Upgrade

Message describing the results of the last upgrade or reinstallation.

Image Filename

Path and filename that identifies where on the host or server the software is located.

Example:

/usr/tftp/switch11.ldc

TFTP Server IP Address

IP address of the host or server on which the software to be installed is located. The default address is 0.0.0.0.
First Hop Address IP address of the first hop router that routes to other networks. The first hop router and its address are needed if the remote host on which the software is located is not on a directly connected network. The default address is 0.0.0.0.
TFTP Timeout Value Amount of time that passes before the next retry.

If the TFTP request is lost, TFTP retransmits the request several times, using the timeout value to determine the amount of time that passes between tries.

The recommended default value is 10 seconds. Use a value greater than 10 seconds if the path over which the installation is to occur is typically slow.
