aIncreases 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.

5.2 Installing the Memory Channel Adapter

Install the Memory Channel adapter in an appropriate peripheral component interconnect (PCI) slot (see Section 2.2). Secure the 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.
