Figure 3-8 shows a system with nine PCIs. In this configuration, a single
KFTIA is in TLSB slot 8 and two KFTHAs are in TLSB slots 7 and 6.
There are nine PCIs, one in the system cabinet and four in each expander
cabinet.
Cabling Guidelines:
1.
The PCI in the system cabinet is connected to the KFTIA in slot 8.
2.
If there is one expander cabinet, the PCIs in it are connected to the
KFTHA in slot 7.
3.
If there are two expander cabinets, the PCIs in the right expander are
connected to the KFTHA in slot 6, and the PCIs in the left expander
are connected to the KFTHA in slot 7.
4.
The cable from the topmost connector on the KFTHA is connected to
the PCI in the lowest position in the expander, the cable from the next
topmost position is connected to the PCI that is above the lowest one
in the expander. The other two cables follow this principle.
To install the cables:
1.
Plan your cabling carefully taking into consideration the above condi-
tions and how the cables are routed and bundled as shown in Figure
3-8.
2.
Each PCI must be connected to a KFTHA or KFTIA. Cable 17-03085-
04 connects the KFTIA to the PCI in the system cabinet, and the
longer cable, the 17-03085-03, connects PCIs in expander cabinets to
KFTHAs in the system cabinet.
3.
Using a flathead screwdriver, install the end of the I/O cable labeled
IOP (P/N 17-03085-0x) to the KFTHA or KFTIA connector. Be sure
the connector is aligned before tightening the screws.
4.
Route the I/O cable(s) as shown in Figure 3-8.
5.
Using a flathead screwdriver, install the end of the I/O cable labeled
PIU to the appropriate PCI shown in Figure 3-8.
6.
Once all the cables are connected place tie-wraps on them and secure
them as best you can in the positions shown in Figure 3-8.
