Figure 156: G16X
3
module
The G16X
3
module has 16 1000BASE-X ports using mini-GBIC (or small form factor pluggable (SFP))
slots.
The G16X 3 ports are oversubscribed to the module’s switch fabric. The module has eight groups of two
ports each. Each group multiplexes traffic into a single full duplex gigabit link to the switch fabric.
To take advantage of this architecture, use a single port in each group before using all of the ports in
any particular group. Table 54 lists the groups for the G16X
3
module.
Populate ports 1, 3, 5, 7, 9, 11, 13, and 15 first; then populate ports 2, 4, 6, 8, 10, 12, 14, and 16.
