158 IBM 9077 SP Switch Router: Get Connected to the SP Switch
Configuration assumptions:
• The SP Switch Router Ethernet media card has been installed according
to Section 4.1, “Ethernet 10/100Base-T Configuration” on page 105 and
works properly.
• The SP Switch Router Adapter card has been installed according to
Section 3.7, “Step-by-Step Media Card Configuration” on page 86 and
works properly.
• The SP Switch Router Adapter card and SP processor node Switch
adapters are in the same IP subnet.
• ARP should be enabled on the SP Switch network to provide the most
flexibility in assigning IP addresses (strongly recommended!).
• If ARP is disabled on the SP Switch network, the IP addresses assigned to
the nodes must be determined by the Switch node numbers. Refer to
PSSP Planning, Volume 2, Control Workstation and Software Environment
for details.
Configuration:
A RS/6000 model F50 with a PCI Ethernet adapter card is connected to port 1
of an Ethernet media card in the GRF 1600. The GRF 1600 SP Switch Router
Adapter card is attached to the SP Switch of SP21, as shown in Figure 53
and Table 14 on page 159. The netmask for all interfaces is 255.255.255.0.
Figure 53. SP Switch - Ethernet Connection
Table 14 on page 159 shows the IP addresses used in our configuration.
