A ServerNet switch weighs six pounds (2.7 kilograms). For c7000 enclosure specifications, see the NonStop BladeSystem
Planning Guide.
Before Cabling the ServerNet Switches in a Single-Zone Topology
1. Verify that a pair of ACHs (one for each external fabric) is installed for the BladeCluster. One
pair of ACHs supports up to eight nodes. For installation instructions, see “Advanced Cluster
Hubs (ACHs)”.
2. Verify that the ServerNet switches in the group.module.slot locations 100.2.5 and 100.3.7
(the first c7000 enclosure) of the BladeSystem that is being added to the BladeCluster have
been configured with quad optical transceivers in ports 15, 16, 17, and 18 for connections
to the ACHs.
3. If necessary, have your service provider upgrade the ServerNet switches in the
group.module.slot locations (X fabric) and (Y fabric) of the NonStop BladeSystem from partially-
to fully-populated quad optical transceivers. This procedure can be done one fabric at a time
without requiring either a system load or a system power cycle.
For instructions for installing ServerNet switches for BladeCluster, ask your service provider
to refer to the Replacing ServerNet Switch FRUs in a NonStop BladeSystem service procedure.
Your service provider should not connect any fiber-optic cables to the ACH until prompted by
the OSM Add Node To ServerNet Cluster guided procedure.
4. Ensure that the cables are labeled at both ends, indicating the node, fabric, ServerNet switch
port, and ACH port number.
