When using a serial cable you must ensure that it is wired correctly as described in Appendix B of the
Getting Started Guide.
TFTP Upgrades
Note that when initiating a TFTP upgrade using the Web interface or CLI, if an incorrect TFTP server IP
address or software upgrade filename is entered you will not be able to correct the IP address or filename
until the TFTP upgrade operation has timed out. The default time out period is 5 minutes.
You can avoid the 5 minute time out period by aborting the upgrade, either using the Abort button in the
Web interface or the Esc character in the Command Line Interface.
Configuring Link Aggregations
When creating a manual aggregation between two systems the ports in the aggregation must not be
physically connected together until the aggregation has been correctly configured at both ends of the link.
Failure to configure the aggregation at both ends before physically connecting the ports can result in a
number of serious network issues such as lost packets and network loops.
LACP Protocol
CAUTION: The LACP protocol is disabled by default in version 3.05 software. Some legacy devices do
not support LACP and 3Com strongly recommends LACP remains disabled on ports connected to these
devices (in rare cases, if LACP is enabled on ports connected to these devices, it can result in incorrect
network configurations).
CD-ROM
When using the setup.exe that displays the splash screen on the CD-ROM you may experience a problem if
you have an early version of virus checker installed on your PC. If you experience this problem the following
error is displayed when the setup.exe is activated:
Application Error
Exception EResNotFound in
Module 0DSCD.EXE at 0016:0B37
Resource TMainForm not found.
You can either:
•
Turn off your virus checking software whilst using the CD-ROM
or
•
Upgrade your virus checking software to the latest version.
