Figure 4-5 Half-Size NIF Installation Examples
Example when half-size and full-size NIFs are to be installed
Two slots must be used to install full-size NIFs. The load on each slot depends on
whether it is located-receiving side or sending side. Determine the line capacity
according to Table 4-24 below. For example, if NE1G-1LA is installed in NIF0+NIF1,
the line speed allowed for NIF2 and NIF3 will be as follows:
150Mbps x 1
= 150Mbps
100BASE-TX x 4
= 400 Mbps
NEOC3-2S
NE100-8T

Not usable
Example A
10BASE-T x 4
= 40 Mbps
NE100-8T
NIF0:
NE100-8T
Example B
Not usable
100BASE-TX x 4
= 400 Mbps
10BASE-T x 4
= 40 Mbps
10BASE-T x 6
= 60 Mbps
= 100 Mbps
