About the Network Interfaces

The Sun Fire V445 server provides four on-board Sun Gigabit Ethernet interfaces,
which reside on the system motherboard and conform to the IEEE 802.3z Ethernet
standard. For an illustration of the Ethernet ports, see
interfaces operate at 10 Mbps, 100 Mbps, and 1000 Mbps.
Four back panel ports with RJ-45 connectors provide access to the on-board Ethernet
interfaces. Each interface is configured with a unique Media Access Control (MAC)
address. Each connector features two LED indicators, as described in
Additional Ethernet interfaces or connections to other network types are available
by installing the appropriate PCI interface cards.
The system's on-board interfaces can be configured for redundancy, or an additional
network interface card can serve as a redundant network interface for one of the
system's on-board interfaces. If the active network interface becomes unavailable,
the system can automatically switch to the redundant interface to maintain
availability. This capability is known as automatic failover and must be configured at
the Solaris OS level. In addition, this configuration provides outbound data load
balancing for increased performance. For additional details, see
