Interface Cables
2.1.1 Setup and Network Connections
The serial port of the eXtended System Control Facility unit (XSCFU) is used for the
following purposes:
■ Connecting a local area network (LAN) port to the system administration
network
■ Monitoring the boot process
■ Changing the initial values of the system controller
The administration network connects the XSCFU to the system administrator's
management console. A direct connection can be used for this purpose. However,
the connection is usually one through a hub or switch specific to the system control
network. To initialize a LAN port, direct administration of the serial port must be
performed.
