Network Connection Procedure

The Sun HPC ClusterTools 3.0 software may—but need not be—already installed on
the nodes before you perform the procedures described in this chapter. The
ClusterTools 3.0 software must be installed before you configure the SCI drivers, as
described in Chapter 3.

Notes for Scrubber Jumper Settings

If the nodes are not already in a power-off state, turn their power switches off and
disconnect their power cables from the power outlet.
Verify that each SCI adapter card's scrubber jumper has the correct setting for the
network configuration in which it will be used.
4 Switchless two-node network – If you are creating a two-node network in which
the nodes will connect directly, not through a switch, set the scrubber jumper at
one end of a connection to ON and the scrubber jumper at the other end of the
connection to OFF.
4 Switched two-node network – If you plan to add one or two nodes to a two-node
network at a later time, you may want to connect the nodes through an SCI switch
when you first set up the two-node network. See the section "Notes for Switched
Two-Node Network" on page 12 for an explanation.
4 Three- and four-node networks – The scrubber jumper on every SCI adapter card
must be set to ON.
