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.

• 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.

• 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" for an explanation.

• Three- and four-node networks - The scrubber jumper on every SCI adapter card must be set to ON.
