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.
