This chapter provides an overview of the 7600 Fast Ethernet Interface
Card and its major features and components.
About the 7600
Card
The 7600 Card provides up to 16 Fast Ethernet fiber optic or copper ports
and is based on multiple ASIC
ZipChip
technology. Featuring a full or half
duplex capability, the 7600 includes fully modular physical interfaces
which can be upgraded in the field with a mixture of 100BASEFx and Tx
ports.

Port Configurations
The 7600 Card provides a base card comprising eight Fast Ethernet
100BASE-Fx (fiber) or 100BASE-Tx (copper) connectors and four optional
Fast Ethernet physical modules, which can be installed in configurations
of two 100BASE-Fx or 100BASE-Tx ports per module.
Fast Ethernet ports on the base card are numbered 1 to 8, left to right;
Fast Ethernet ports on the upper layer physical modules are numbered 9
to 16, left to right. Figure 1-1 shows the front panel of the 7600 Card
with the maximum number of Fast Ethernet physical modules installed.
Figure 1-2 shows the front panel of the 7600 Card with only the base
configuration installed.
