1-2 Sun Netra CP3240 Switch Installation Guide • September 2009
1.1 System Requirements
The following sections briefly describe the minimum system requirements and the
configurable features. Links are provided to other chapters and appendices
containing more detailed information.
1.1.1 Connectivity
The switch can work in any AdvancedTCA shelf. It is mainly designed to be used as
hub blade, however, it can also operate a node or a full-mesh blade.
1.1.1.1 Hub Connectivity
In AdvancedTCA. the hub board defines the system, so it is important that it be put
in the correct slot. In all shelves there are two slots specifically designated for hub
boards, logical slots 1 and 2. If the slots are not labeled, these slots are easily
identifiable because they have a larger number of Zone 2 connectors than the other
slots (the only slots with all five Zone 2 connectors).
Base is always routed in a dual star. This means every node slot has a Base channel
routed to each of the hub slots. Independent of how the Fabric is used, a hub board
is always needed for Base. If full mesh node boards are used in a full mesh shelf, a
hub board is not needed for Fabric.
1.1.2 Electrical and Environmental
The switch has the following power requirements:
