1. If the control workstation is connected to the SP system through a 10Base-2
(thin coax) network, the SP Switch Router may be connected to the network
through a customer supplied 10Base-T to 10Base-2 hub (or bridge), such as
the IBM 8222 Ethernet Workgroup Hub.
All coax and twisted pair Ethernet cables must be supplied by the customer.
2. If the control workstation is connected to the SP system through a twisted pair
(TP) Ethernet LAN, the SP Switch Router may be connected to an available
port on the Ethernet hub (switch).
All coax and twisted pair Ethernet cables must be supplied by the customer.
3. The RS/6000 SP Switch Router may also be connected to an additional
10Base-T adapter (such as F/C 2992) that has been installed directly in the
control workstation for this purpose. If you decide to use this method, you
must set up a separate Ethernet subnet for the SP Switch Router.
When using separate 10Base-T adapters for the control workstation
connection, in addition to the 10Base-T adapter, you must also supply a
twisted pair Ethernet cable with a crossed connection appropriate for use
between two network interface cards.
4. The SP Switch Router may also be indirectly connected to the control
workstation using an external network. In this configuration, the Ethernet
connection from the router's control board is attached to external network
equipment. The external network connection to the control workstation may
be:
– A separate (non-SP Ethernet) Ethernet
– ATM
– FDDI
6.4.2 Connecting to multiple SP systems
If you are planning to connect one SP Switch Router to multiple, independent SP
Systems, you will need:
One SP Switch Router adapter for each SP system being connected.
A Switch Router adapter cable to connect each of the adapters to an SP
Switch located in each of the SP systems.
An Ethernet connection from the SP Switch Router's control board to an
external network. The Router's control board Ethernet connection is de0 and
uses 10/100BaseT Ethernet.
Connections from the external network must attach to the control
workstations administering each SP system. The external networks may be:
– Other Ethernets
