UTCA-5503 User Manual 10
The MCH is a key element of the uTCA architecture (see Figure 2.1). It is used in
uTCA systems and applications to provide
! Carrier / shelf system management
!
Switching capabilities for the basic fabric interface (“common options”)
! Clock distribution
! Fat pipes fabric switching capabilities
For details of the uTCA architecture, refer to PICMG® MicroTCA.0 R1.0, Micro Tele-
communications Computing Architecture specification.

2.1 Mechanical Basics
The MCH consists of a stack of 4 PCB layers, labeled as PCB1 to PCB4 as shown in
Figure 2.2.
Figure 2.2 MCH PCB Naming Conventions
UTCA-5503, implemented on PCB1 of Advantech’s MCH, contains the basic features
that every MCH must support as well as interface connections to PCB2 to PCB4.
!
the management controller called the MCMC
! the common options switch fabric
All other PCBs except for PCB1 are optional for an MCH.
