Introduction
The Advantech MicroTCA™ Carrier Hub UTCA-5503 combines into a single AdvancedMC Module that controls and manages infrastructure and the interconnect fabric resources
necessary to support up to twelve AdvancedMCs in a MicroTCA shelf:
. A Primary Gigabit Ethernet fabric on Common Options Fabric A
. MicroTCA Carrier Management Controller (MCMC) functions to configure and control the elements
Where redundancy is required, two MCHs permit the creation of highly reliable systems.

design offers flexibility for clock, I/O and alarm panel requirements.
When redundant MCHs are installed, failures in the management circuitry on one MCH
can be handled by a failover to the other MCH. The MCMC LAN interface is available for
optional remote management via the front panel RJ-45 connector or for optional routing
An additional PCB2 module can be added to the MCH for enhanced clock distribution and

external clock connectivity depending on customer specific requirements. Flexibility has
been built into the Front PCB2 module design in order to meet a wide range of current
and future Clock, I/O and Alarm panel requirements.
E-Keying
Electronic keying (E-Keying) is the responsibility of the Carrier Manager and ensures that
all AdvancedMCs and MCHs installed in a Shelf are compatible before they are permitted
to power-up and enable their fabric links.
Basic Interconnect Fabric
In its basic configuration, the MCH acts as the Gigabit Ethernet hub of a star network,
providing centralized switching and high-speed connectivity to each AdvancedMC. The
Gigabit Ethernet Switch on the MCH provides an unmanaged layer 2, non-blocking,
low-latency Gigabit Ethernet Switch.
Two MCHs can be used to implement a dual-star topology required for reliability. This
is further enhanced by a Gigabit Ethernet Update Channel Port between the two MCHs.
A front panel RJ-45 or SFP provides further network expandability with Gigabit Ethernet
uplink ports for external interconnects.
This basic configuration provides a solid solution to the most cost sensitive application
requirements.
