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.
