PROBLEM SOLVING
If you suspect a problem, carry out these steps before
„
Check that the correct management software is being
used on the Switch.
contacting your supplier:
„
Check that the Interconnect Module is correctly
installed in the Switch.
If the Module Status LED on the front of the Switch is
flashing yellow, the Module is installed but not
supported by the Switch. The Switch will continue to
operate normally but you must upgrade the
management software on the Switch for it to recognize
and support the Module and enable the Module’s
ports. You can download the latest version of the
management software from the 3Com website at:
When you insert the Module into the Switch, push the
Module in until the Module’s back plate is in full
contact with the Switch’s chassis. Secure the Module to
the Switch by tightening the three captive screws fully
with a screwdriver. If an error is indicated during the
Power On Self Test, check that the module has been
correctly inserted.
Alternatively, if you received a CD-ROM with your
Module, you can upgrade your Switch with the
management software contained on the CD-ROM.
„
„
Check that the Interconnect cabling is correctly
connected and secured.
.
Check that the Switch, into which the Interconnect
Module is fitted, is powered-up.
