Modules - 3Com CoreBuilder 2500 Getting Started Manual

Modules

Each CoreBuilder 2500 system can accommodate up
to two Ethernet modules in slots 3 and 4, and up to
two high-speed modules (FDDI, Fast Ethernet, or
ATM) in slots 1 and 2 for a maximum of two
high-speed ports and sixteen Ethernet ports.
Because of the range of media options available, a
variety of configurations is possible.
The following figures illustrate the available
Ethernet, FDDI, Fast Ethernet, and ATM modules.
