28 CHAPTER 3: INSTALLING AND SETTING UP THE LAYER 3 MODULE
Handling the Layer 3
Module
The Layer 3 Module contains parts that are susceptible to electrostatic
discharge damage. To prevent damage, please observe the following:
■ Always wear an anti-static wristband connected to a suitable earth
point.
■ Always transport or store the module in appropriate anti-static
packaging.
■ Do not remove the module from its packaging until you are ready to
install it.
■ Handle the module only by its edges and front panel and avoid
touching any of the connectors or components on the module.
Device Support The SuperStack II Switch 1100/3300 family supports the Layer 3 Module.
3Com recommends that you check the Release Notes that accompany
the module for information on any additional device support.
Pre-installation
Procedure
This section describes the procedures you need to follow before installing
the Layer 3 Module.
Upgrading Software To determine the version of software installed on the Switch, do one of
the following:
■ Use the Unit Status page on the Switch’s Web interface.
■ Use the Switch system display command. The number shown in the
Operational Version field is also the version number for the software.
For further information, see your Switch management guide.
If your Switch does not already have version 2.4 or later of the Switch
software installed, you must upgrade the Switch software before
installing the Layer 3 Module.
