About the Network Interfaces
The Sun Fire V480 server provides two on-board Ethernet interfaces, which reside on
the system centerplane and conform to the IEEE 802.3z Ethernet standard. For an
illustration of the Ethernet ports, see
FIGURE 2-4
, “Back Panel External Ports” on
page 21. The Ethernet interfaces operate at 10 Mbps, 100 Mbps, and 1000 Mbps.
Two 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 LEDs, as described in
TABLE 4-1
.
Additional Ethernet interfaces or connections to other network types are available
by installing the appropriate PCI interface cards. 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
operating environment level. For additional details, see “About Redundant Network
Interfaces” on page 55.
The Ethernet driver is installed automatically during the Solaris installation
procedure.
For instructions on configuring the system network interfaces, see:
