2.4 Digital PAD Setting
The PA-24DTR card is equipped with a mask ROM in which the following typical PAD patterns have been
already written. PAD value is determined by selecting a desired PAD pattern, which can be done by key
setting of the SW 58 (elements 4, 5, 6) on the card, and programming of the PAD data by the ARTD com-
mand - CDN = 30 (PAD). The PAD patterns and ARTD data correspond as follows.

3.1 Mounting HUB (PA-M96) in a PIM
Mount the HUB (PA-M96) card in an appropriate slot of a PIM as shown below. When the MAT is con-
nected via a HUB card, be sure to use a dedicated HUB for the Fusion link.
Note:HUB (PA-M96) can be mounted wherever in a PIM of any IMG stack. However, if your system is 1-IMG
type, mount the HUB in PIM0.

4.1 Connecting DTI-FCH Front Cables
Connect the furnished front cable to the connectors on the DTI and FCH cards. Use DTI and CN2 connec-
tors on the FCH and DTI cards respectively. Since an FCH card is equipped with one Handler circuit, a
maximum of five FCH cards can be connected to a DTI card. (See Figure 4-10.) However, if a DCH card
is also cascaded, a maximum of three FCH cards can be added to the DTI card. (DCH is equipped with two
Handler circuits per card.)

4.2 Connecting 10 BASE-T Cables
Figure 4-11 shows sample cable connections, where HUB (PA-M96) cards are provided in a dual configu-
ration and the FCH (PA-FCHA) card is located in PIM 1 (1-IMG system/IMG0). When HUB cards are pro-
vided in a dual configuration, the two HUB cards must be connected on each front edge connector using a
10 BASE-T cross cable. However, when dual LANIs (LANI-A and LANI-B) are used for each CPU, the
cross cable connection between HUBs for FCH#0 and #1 is not necessary.
Note:The Ethernet cables shown in the examples in this section are NOT available from NEC. These cables must
be provided by the customer, depending on the system configuration. See “Chapter 6 Connecting 10 BASE-
T Cables.”

4.3 10 BASE-T Connection Procedure
The pattern for 10 BASE-T cable connections may vary, depending on the system configuration (such as
number of IMG stacks or the mounting location/number of the FCH/HUB cards, etc.). According to your
system configuration, connect necessary Ethernet cables:
4.3.1 Procedure for 1-IMG System
If your system is 1-IMG type, the 10 BASE-T connection should use either of the following cables:
1. Cable unit specified as SR1201 ETIF CAU-n
2. Cables, other than those of SR1201 ETIF CAU-n, that are provided by the user
Based on the cable type, perform the following:
4.3.2 When using cable unit SR1201 ETIF CAU-n
1. Referring to any of Figure 4-13 through Figure 4-15, connect the 10 BASE-T straight cables, be-
tween the LANI (PZ-PC19) and HUB (PA-M96) cards, and between the HUB and FCH (PA-
FCHA) cards. If the HUB is in a dual configuration, also connect the 10 BASE-T cross cable be-
tween HUB#0 and HUB#1.
When dual LANIs are used in both Slot 00 and 03 of CPR#0/CPR#1, be sure to use at least two
HUB cards. Use one HUB for the internal LANI (in Slot 00) and use the other HUB for external
LANI (in Slot 03, available for Series 7300 Release 3 software or later). If FCH is also in a dual
configuration, the 10 BASE-T cross connection between the two HUBs is not required. 
2. If your system needs more FCH (PA-FCHA) and/or HUB (PA-M96) cards, provide the required
Ethernet connection(s) for the added card(s) using the following cables:
 When adding FCH card in PIM0: UTP CTG5 ST CA-D
 When adding HUB card in PIM0: UTP CTG5 CRS CA-D
 When adding FCH card in PIM1: UTP CTG5 ST CA-K
 When adding HUB card in PIM1: UTP CTG5 CRS CA-K
 When adding FCH card in PIM2: UTP CTG5 ST CA-M
 When adding HUB card in PIM2: UTP CTG5 CRS CA-M
 When adding FCH card in PIM3: UTP CTG5 ST CA-N
 When adding HUB card in PIM3: UTP CTG5 CRS CA-N
Note:The cables, cited above and used in Figure 4-13 through Figure 4-15, are for the 1-IMG system only (not
available in the 4-IMG/IMX-U system).
