System Overview
1.1 Description
The Centellis 4100 system is a high availability AdvancedTCA (Advanced Telecom Computing
Architecture) system. The PICMG 3.X AdvancedTCA Specifications define components for high-
performance services solutions. It is an architecture for highly-available and scalable high-
speed interconnect technologies.
A high-availability system consists of software and redundant hardware to ensure five-nines
(99,999%) uptime. This means that a system is unavailable for no more than 5.26 minutes per
year.
The system is always equipped with:
 Dual star backplane with base and fabric interface providing connector interfaces for
power distribution, input/output connectivity between front blades and mechanical
alignment and support
 Subrack providing attachment points for backplane, alignment, support and mechanical
engagement for insertion and extraction of front blades and RTMs
 Two Artesyn Embedded Technologies - Embedded Computing ATCA-M100 shelf
manager boards
Each AdvancedTCA blade and Field Replaceable Unit (FRU) provides connections to the
shelf manager through an Intelligent Platform Management Bus (IPMB).
 Two Artesyn Embedded Technologies - Embedded Computing ATCA-A100 alarm boards
 12 node slots which can be equipped with AdvancedTCA node blades
 Two hub slots which can be equipped with AdvancedTCA hub blades
 14 slots at the system's rear side which can be populated with 14 RTMs
These RTM connections provide user-defined input and output connectivity to the
corresponding front blades.
 Four IPMC enabled intelligent blowers
 Four single entry DC Feed intelligent Power Entry Modules (PEMs) with 50A breaker and
line filter
 Air filter
 Rear ESD wrist strap sockets and grounding studs
