Video port
Your appliance comes with an integrated super video graphics array (SVGA) video
controller. This controller is not removable, but you can disable it by installing a PCI
video adapter.
Ethernet port
Your appliance comes with an integrated 10/100 Ethernet controller. This controller
provides an interface for connecting to 10-Mbps or 100-Mbps networks and
provides full-duplex (FDX) capability, which enables simultaneous transmission and
reception of data on the Ethernet local area network (LAN).
To access the Ethernet port, connect a Category 3, 4 or 5 unshielded twisted-pair
(UTP) cable to the RJ-45 connector on the rear of your appliance.
Notes:
1. The 100BASE-TX Fast Ethernet standard requires that the cabling in the
network be Category 5 or higher.
2. If you plan to use the IBM Advanced Appliance Configuration Utility to configure
and manage your appliance, be sure to connect the built-in Ethernet connector
to the same physical network as your systems management console.
Configuring the Ethernet controller: When you connect your appliance to the
network, the Ethernet controller automatically detects the data-transfer rate
(10 Mbps or 100 Mbps) on the network and then sets the controller to operate at
the appropriate rate. That is, the Ethernet controller will adjust to the network data
rate, whether the data rate is standard Ethernet (10BASE-T), Fast Ethernet
(100BASE-TX), half duplex (HDX), or full duplex (FDX). The controller supports
half-duplex (HDX) and full-duplex (FDX) modes at both speeds.
The Ethernet controller is a PCI Plug and Play device. You do not need to set any
jumpers or configure the controller for your operating system before you use the
Ethernet controller.
Failover for redundant Ethernet: The Ethernet adapter that is on the planar does
not support a failover function. However, if you install two or more 10/100 Ethernet
PCI optional adapters or two or more Gigabit Ethernet adapters, and you connect
them to the same logical segment as an additional (primary) Ethernet adapter, you
can configure the appliance to support a failover function. In failover mode, if the
primary Ethernet controller detects a link failure, all Ethernet traffic associated with it
is switched to the redundant (secondary) controller. This switching occurs without
any user intervention. When the primary link is restored to an operational state, the
Ethernet traffic switches back to the primary Ethernet controller. The switch back to
the primary Ethernet controller can be automatic or manually controlled, depending
on the setup and operating system.
Advanced systems management (service) port
Your appliance has one communication port dedicated to the Netfinity
System Management Processor. This port uses a standard D-shell serial-port
connector, labeled "Management."
