5.5.1.1 Connecting MC1 or MC1.5 Link Cables in Virtual Hub Mode
For an MC1 virtual hub configuration (two nodes in the cluster), connect the
_____________________ Caution _____________________
Be very careful when installing the link cables. Insert the cables straight in.
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.
______________________ Note _______________________
With the TruCluster Server Version 5.1 product and virtual hub mode, there is no longer a restriction requiring that mca0 in one system be connected to mca0 in the other system.
5.5.1.2 Connecting MC1 Link Cables in Standard Hub Mode
If there are more than two systems in a cluster, use a standard hub configuration. Connect a
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 1 in one hub, you must connect the other adapter in that system to a linecard installed in slot 1 of the second hub.
