Gently push the cable’s connector into the receptacle, and then use the
screws to pull the connector in tight. The connector must be tight to ensure
a good ground contact.
If you are setting up redundant interconnects, all Memory Channel adapters
in a system must have the same jumper setting, either VH0 or VH1.
5.5.2.2 Installing MC2 Cables in Virtual Hub Mode Using Optical Converters
If you are using optical converters in an MC2 configuration, install an optical
converter module (CCMFB) when you install the CCMAB Memory Channel
PCI adapter in each system in the virtual hub configuration. You should
also connect the CCMAB Memory Channel adapter to the optical converter
with a BN39B-01 cable. When you install the CCMFB optical converter
module in the second system, you connect the two systems with the BN34R
fiber optics cable (see Section 5.3).
5.5.2.3 Connecting MC2 Link Cables in Standard Hub Mode (No Fiber Optics)
If there are more than two systems in a cluster, use a Memory Channel
standard hub configuration. Connect a BN39B-04 (4-meter) or BN39B-10
(10-meter) link cable between the Memory Channel adapter and a linecard
in the CCMHB hub, starting at the lowest numbered slot in the hub.
If you are setting up redundant interconnects, the following restrictions
apply:
• Each adapter installed in a system must be connected to a different hub.
• Each Memory Channel adapter in a system must be connected to
linecards that are installed in the same slot position in each hub. For
example, if you connect one adapter to a linecard installed in slot
0/opto
in one hub, you must connect the other adapter in that system to a
linecard installed in slot
0/opto
of the second hub.

You cannot install a CCMLB linecard in slot

5.5.2.4 Connecting MC2 Cables in Standard Hub Mode Using Optical Converters
If you are using optical converters in an MC2 configuration, install an optical
converter module (CCMFB), with attached BN34R fiber optics cable, when
you install the CCMAB Memory Channel PCI adapter in each system in the
standard hub configuration. You should also connect the CCMAB Memory
Channel adapter to the optical converter with a BN39B-01 cable.
