CHAPTER 2 NDA-24307 Pag e 6 Issue 1 SYSTEM MAINTENANCE OUTLINE 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 maximum four Local nodes compose a single network system via the Fusion link.

Note 1:The connections, shown in this figure, are only an example. Actual cable runnings may vary, depending on your
system configuration. (Refer to the “Installation Manual” for more details)
Note 2:The mutual 10 BASE-T (Ethernet) connections must be within 328 feet (100m) in their distance. If the distance is
longer [e.g. , Fusion Link is provided also with other distant IPX node(s)], use FCH (PA-FCHA) card as a protocol
converter for the Fusion-link data. For more details, refer to the “Fusion Network System Manual.
[Details on Ether Cable Connections]
ISW and each LN can achieve a Fusion link by physically connecting themselves via the 10 BASE-T cables. This figure
shows an example where the CPR-accommodated LANI cards (internal LANI: PCI slot 00) are mutually connected via
HUB0/HUB1 (PA-M96) cards in PIM0 of LN0, IMG0 (HUB0 for CPU0 of all nodes, HUB1 for CPU1 of all nodes.)

[ 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) cards in PIM0 of LN2, IMG0 (HUB2 for
CPU0 of all nodes, HUB3 for CPU1 of all nodes).

The IPX-U system can use both IOC (PH-IO24) card or each CPR-accommodated LANI (PZ-PC19) card as
an interface for the connection to a MAT. This figure shows an example where a MAT is connected via the
LANI card in PCI slot 01 of each LN/ISW.
This figure is an example where a MAT is connected to LN1 via the 10 BASE-T cables
(Ethernet). As seen from this, the MAT, a single terminal connected to the Ether, can control
the whole system status, thus capable of a single-point entry to each LN and ISW.
Note 1:
When connecting the MAT by this way, be sure to use dedicated HUB (PA-M96) card(s).
Note 2:Because ISW has no universal slot for external HUB cards, connect the 10 BASE-T ca-
bles (from the ISW) to a MAT-dedicated HUB in any of the LNs (LN0 - LN3). In this ex-
ample, the cables are ISW) to a MAT-dedicated HUB in any of the LNs (LN0 - LN3). In
this example, the cables are connected to HUB in LN1.
