Upgrading Software
When 3Com issues a new version of the software
image for the Switch, you can obtain it from
3Com’s information delivery systems, described in
“
Online Technical Services” on page F-1.
For upgrading ATM OC-3c Module software, refer
to the “SuperStack II Switch ATM OC-3c Module
User Guide”.
You use the Software Upgrade screen to download
new software images. The protocol used for down-
loading software images is TFTP running over
UDP/IP or IPX.
CAUTION: Before attempting to download, note
the following:
■
The download only works over the network; it
does not work through the console port.
■
The download does not work over a Virtual LAN
Trunk (VLT) if you have a Boot software version
lower than version 2.0.
■
The download does not work over an ATM link.
