2.1.1 Configuration of the System
The NEAX2400 IPX IPX-U system (referred to in the remainder of this manual as “the system”) is
configured by a single Inter-node Switch (ISW) and a maximum of 4 Local Nodes (LNs). Refer to
figures in this section. The ISW and LNs are connected via the Fusion link, with Ethernet and physical
PCM cables connected to each other. Figure 2-3 provides an overall image of system configuration. A
two-module ISW and...

[ Details on Ether Cable Connections: When Dual LANIs are used for each CPU ]
When dual LANIs are used for each CPU, the whole second LANIs (external LANI:  PCI slot 03) must also be
connected in addition to the first LANIs explained on the previous page.  This figure shows an example where the
second LANIs are connected to the additional HUB2/HUB3 (PA-M96)...
