Connection between the MDFU or MDFU-E and Backplane

Introduction
Set up the connection between the main distribution frame and the system using CABLUs (pre-
fabricated cabling units) with the following characteristics:
System side: SIPAC 1 SU connector(s)
●
Cable: 16 x 2 x 0.4
●
Main distribution frame side:
●
– Not for U.S.: Different distribution strips or carriers (Figure 4-70)
– For U.S. only: 50-pin CHAMP jacks
Not for U.S.: Not more than 9 CABLUs per MDFU (Figure 4-71) and 21 CABLUs per MDFU-E
(Figure 4-72) with one 16-TW strip or 25-TW strip (9 x 30 mm) strip can be implemented.
In special cases where the prefabricated CABLUs cannot be used,
used.
Not for U.S.: CABLUs for the slots containing peripheral boards (Figure 4-88)

Assignment Route 16 TW to the MDFU or MDFU-E via SU Xx8 and 8 TW via SU Xx9,
with using a standard cable (with 16 TW) for each connection. Connect both ca-

or
SLA24N

Note: If replacing an old system, for example, you can use existing standard
CABLUs with splitting strips for 16 TW. If an SLMO24 board is used, you
must lay an additional CABLU (SU Xx9) to the MDFU or MDFU-E.
Assignment S
with A direct connection is set up to the NT or networked system via the back-
TMS2 plane connector SU Xx9 and a special cable (see Section 3.3.42, "TMS2
