othersystems, the bandwidth is decreased.
The MC2 linecard (CCMLB) has two jumpers, J2 and J3, that are used
to enable fiber optics mode. The jumpersare 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 ison theright. The MC2 linecard jumpers
are described in Table 53.

5.2 Installing the Memory Channel Adapter
Installthe Memory Channeladapter in an appropriate peripheral component
interconnect(PCI) slot(see Section 2.2). Securethe module at the backplane.
Ensure that the screw is tight to maintain proper grounding.
The Memory Channel adapter comes with a straight extension plate. This
fits most systems; however, you may have to replace the extender with an
angled extender (AlphaServer 2100A, for instance), or for an AlphaServer
8200/8400, GS60, GS60E, or GS140 remove the extender completely.
