(single- and multi-) mode versions.
This chapter describes how to install the FDDILink module into the NETBuilder II
bridge/router and includes the following procedures and information:
■
Software compatibility
■
Hardware requirements
■

Software
Compatibility
All versions of the FDDILink module require version 9.3 or later of the
NETBuilder software. The module is not backward compatible and does not
support network boot or network dump procedures.
Hardware
Requirements
Use the information in this section to determine if your chassis will
accommodate the FDDILink module.
The newer 4-Slot chassis (assembly part number 20-0250-xxx or 20-0406-xxx),
8-Slot chassis (assembly part number 20-0249-xxx or 20-0407-xxx) or any
chassis labeled “EZBuilt” have one ejector tab for each module slot. The CEC
module slot, however, has two ejector tabs on all chassis. These new chassis
have a removable center column that allows for the installation of
extended-format modules, such as the FDDILink module.
The original 4-Slot and 8-Slot chassis do not have a removable center divider
between the slots and cannot accommodate extended-format modules.
Original 4-Slot and 8-Slot chassis have two ejector tabs for each module.
If your chassis does not have a removable center divider, but is still an older
model (product number 20-0250-xxx or 20-0244-xxx), you need a field
upgrade kit. To install FDDILink modules into the bottom slot of an original
4-Slot or 8-Slot chassis, you need to install EMI spring clips to ensure continued
compliance with emissions requirements. If your chassis does not already have
clips, contact your 3Com service organization to obtain spring clips
and
