Increases the maximum sustainable bandwidth for 8x00 systems. If the jumpers are in this position for
other systems, the bandwidth is decreased.
The MC2 linecard (CCMLB) has two jumpers, J2 and J3, that are used
to enable fiber optics mode. The jumpers are located near the middle of
the module (as you view the jumper side of the module with the endplate
in your left hand). Jumper J2 is on the right. The MC2 linecard jumpers
are described in Table 5–3.
