This chapter describes how to cable your
™
CoreBuilder 2500 system for connection to your
network. It describes how to cable:

Ethernet modules

Fast Ethernet modules
FDDI modules
ATM modules
The optical bypass switch
The system processor serial ports
The sections on Ethernet, Fast Ethernet, FDDI, and
ATM media options include sample network
configurations and instructions for connecting each
type of media option to the network.
When all your Ethernet, Fast Ethernet, FDDI, and
ATM system network connections are complete, see
Chapter 5: System Power
If you are staging the system, you do not need to
connect it to the network at this point. However, to
view possible error messages while the system is
running power-up diagnostics, you must connect a
terminal, workstation, or a PC with terminal
emulation to the system's terminal serial port.
Up.
Ethernet Modules
Your Ethernet segments connect to 3Com's
CoreBuilder 2500 system through Ethernet
modules, which have various media interface
options. Depending on your system configuration,
your system may support up to 16 Ethernet ports.
This section describes the Ethernet modules and
possible configurations and gives instructions for
making network connections. Available Ethernet
modules include:
10BASE-T (RJ-21)
10BASE-T (RJ-45)
10BASE-5 (AUI)
10BASE-FL
10BASE-2 (BNC)
Unterminated 10BASE-2 (BNC)
For pinout information for each module, see
Appendix B: Module and System Pinouts
appropriate module installation guide.
To configure the system for management access
through the Ethernet ports, see
Setup for Management
or the
