Chapter 3. Installation and Configuration
The SP Switch Router functions as an IP router to provide high-speed data
communication links between SP processor nodes and external networks or
hosts. The SP Switch Router Adapter media card connects to the SP Switch
board in an SP system as shown in Figure 28.
Figure 28. Connecting the GRF to the SP Switch and the CWS
The SP Switch Router Adapter card also transmits data to/from other types of
media cards across the SP Switch Router’s internal switch core. These media
cards include HIPPI, HSSI, FDDI, ATM OC-3c, ATM OC-12c, 100Base-T
(Fast Ethernet), and other SP Switch Router Adapter cards. The SP system
manages the SP Switch Router Adapter card as a dependent node, under the
control of the SP SNMP Manager running on the SP Control Workstation and
the Primary node of the SP Switch. To learn more about dependent nodes,
see Chapter 1, “Dependent Node” on page 3. Once powered on and started
up, the SP Switch Router can be configured and managed remotely, either via
a site’s administrative network, or using Telnet from the CWS.
Information about procedures performed from the SP CWS are found in the
"Managing Extension Nodes" chapter in
