In an MC2 configuration, you can use a CCMFB optical converter in conjunction with the MC2 CCMAB module to increase the distance between systems.

The BN34R fiber optics cable, used to connect two CCMFB optical converters, is available in 10-meter (BN34R-10) and 31-meter (BN34R-31) lengths.

Always check a Memory Channel link cable for bent or broken pins. Be sure that you do not bend or break any pins when you connect or disconnect a cable.

For AlphaServer 1000A systems, the Memory Channel adapter must be installed on the primary PCI (in front of the PCI-to-PCI bridge chip) in PCI slots 11, 12, or 13 (the top three slots).

For AlphaServer 2000 systems, the B2111-AA module must be at Revision H or higher.

For AlphaServer 2100 systems, the B2110-AA module must be at Revision L or higher.

Use the examine console command to determine if these modules are at a supported revision as follows:

P00>>> examine -b econfig:20008 econfig: 20008 04

P00>>>

If a hexadecimal value of 04 or greater is returned, the I/O module supports Memory Channel.

If a hexadecimal value of less than 04 is returned, the I/O module is not supported for Memory Channel usage.

Order an H3095-AA module to upgrade an AlphaServer 2000 or an H3096-AA module to upgrade an AlphaServer 2100 to support Memory Channel.

For AlphaServer 2100A systems, the Memory Channel adapter must be installed in PCI 4 through PCI 7 (slots 6, 7, 8, and 9), the bottom four PCI slots.

For AlphaServer 8200, 8400, GS60, GS60E, or GS140 systems, the Memory Channel adapter must be installed in slots 0-7 of a DWLPA PCIA option; there are no restrictions for a DWLPB.

If a TruCluster Server cluster configuration utilizes multiple Memory Channel adapters in standard hub mode, the Memory Channel adapters must be connected to separate Memory Channel hubs. The first Memory Channel adapter (mca0) in each system must be connected to one Memory Channel hub. The second Memory Channel adapter (mcb0) in each system must be connected to a second Memory Channel hub. Also,
