Task 8: Install the Cluster Switches

You must install the X-fabric and Y-fabric cluster switches before you can add a node

to the cluster. This task includes installing the cluster switches, routing fiber-optic

cables and, if necessary, updating the ServerNet II Switch firmware and configuration.

1. Install the cluster switches as instructed in the ServerNet Cluster 6770 Hardware

Installation and Support Guide.

After the cluster switches are installed, you can skip this task when adding the

remaining nodes.

2. Route the fiber-optic ServerNet cables as instructed in the ServerNet Cluster 6770

Hardware Installation and Support Guide.

3. Use Table 3-3 on page 3-13 to decide if you need to update the firmware and

configuration loaded on the ServerNet II Switch subcomponent of each cluster

switch.

Note. For cable-management purposes, you can connect the fiber-optic cables to the

ServerNet II Switch ports inside the cluster switch enclosures. However, do not connect

the fiber-optic cables to the MSEBs until you are instructed to do so by the guided

procedure for configuring a ServerNet node.

Caution. When you receive a cluster switch from HP as new equipment or as a replacement

unit, the ServerNet II Switch subcomponent is preloaded with T0569AAA firmware and

configuration files. T0569AAA is not compatible with some clusters. Before installing the cluster

switch, you might have to update the firmware and configuration files to T0569AAB or a

superseding SPR. A cluster switch running T0569AAA will not be recognized as a valid peer if

connected to another cluster switch running T0569AAB or a superseding SPR.
