Upgrading or
Reinstalling Software
An upgrade replaces the current version of software with a newer version.
A reinstallation reloads the module 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 module 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 Upgrade
The module's LEDs provide information regarding the progress of an installation or
upgrade. If the TFTP file transfer is successful, a CRC of the image received at the
module is performed.
Process:
LED |
Description |
VNbus Traffic LED (upper): green VNbus Status (lower): yellow |
CRC is in progress. |
VNbus Traffic LED (upper): yellow VNbus Status (lower): green |
CRC detects an error. |
VNbus Traffic LED (upper): green VNbus Status (lower): green |
The image is being written to flash,
following a successful CRC. |
VNbus Traffic LED (upper) and VNbus Status
LED (lower) both flash alternating green and
yellow for about 10 seconds, then remain
solidly lit (either green or yellow) for another 10 seconds. |
The process of writing the image to flash
is complete. |
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. |
