Application Module cabling
Two types of cables interconnect Application Module components. These
include
¥ power harness cables
¥ I/O cables
!
CAUTION
Risk of system interruption
Be careful when running cables in the AEM. Ensure that
cables are not looped or kinked. Try to route cables
parallel to each other as much as possible. By doing so,
you can avoid consequent hardware failures.
Power cables
Power to the AEM is fed to the MPDU. Power harnesses conduct power
from the MPDU to the power supply in the Application Module. To cable
an Application Module to the proper circuit breaker on the MPDU, connect
the input power harness (NT7D55AC or NT7D55AD) as follows:
¥ If the Application Module is on the left-hand side of the AEM (next to
the MPDU), connect the power harness to connector P3 on the back of
the MPDU.
¥ If the Application Module is on the right-hand side of the AEM,
connect the power harness to connector P4 on the back of the MPDU.
If the Application Module is installed in the AEM before it is shipped, the
power harness to the MPDU is already connected. Check to make sure the
connection has remained firmly mated during shipping and installation.
Table 76 lists Application Module power harnesses and their applications.
Figure 57 is a power harness wiring diagram for the Application Module.
