BIOS, embedded Linux and BSP The computer domain’s embedded software contains BIOS for main CPU processors (such as in CPU blade), boot and reset logic, as well as an embedded Linux operating system as part of the board support software package (BSP) in all hardware units with unit computers. This software resides in the local flash memory of each unit.

Network interface SW Network interface software controls the external traffic flowing through blades and AMC modules with network interfaces. Synchronization SW (optional, included if the network element uses synchronization) Synchronization software consists of software in a system manager (on CPU blade or CPU AMC) and synchronization software in a hub blade or in a clock generator module. It is used for controlling the way in which synchronized clock signals are distributed to the rest of the units. DSP SW (optional, included if the network element does signal processing) The signal processing software on the DSP blade runs on an OSE operating system, while the unit computer runs embedded Linux. HW management SW Hardware management software consists of software related to shelf and system management, including hardware management controller firmware, shelf manager software, communication over IPMB-0 and IPMB-L, management communication over the base interface using RMCP (remote management control Protocol) and RPC (remote procedure call protocol), and remote access to blades and AMCs (serial over LAN). The HW management domain includes also FRU information storages in all hardware products that have a hardware management controller. Software management (not illustrated) Software management software handles all embedded software updates.

Benefits of ATCA The main strength of ATCA is in its versatility, its ability to support larger volumes, and its capacity to harmonise different platforms. In the long run, ATCA will allow faster time to market and lower costs in terms of both equipment and development, as it will be possible to employ a wide variety of building blocks with minimal modifications. •

Modularity and configurability ATCA allows diverse applications to be created in one platform using multiple modules with various interfaces, including CPUs, DSPs, and storage media from different manufacturers. Redundancy ATCA features many levels of redundancy throughout the system, achieving 99.999% availability (five-nines or carrier grade availability). The option to allow less demanding applications to utilise non-redundant configurations for lower cost is also possible. Support for Ethernet switching fabric ATCA specifications support various serial-type switching fabrics, such as Ethernet and PCI Express. The Nokia Siemens Networks ATCA HW platform currently uses 10 Gigabit and 40 Gigabit Ethernet technology. Scalable capacity Scalability in ATCA is enabled by a centralized switching hub, interconnected to all shelf slots in a star configuration. This allows handling of full-duplex data rates up to 560Gbit/s per 16-slot shelf when using a 40 Gbit/s switching fabric. With the 16-slot shelf, capacity can be scaled upwards by adding the necessary amount of blades, RTMs and AMC modules. On the cabinet level, more shelves or even cabinets can be added.

Hardware architecture

Open MGW/Open BGW Hardware Description

3 Hardware architecture The network element consists of a set of basic ATCA hardware building blocks: cabinet, PDUs, shelf, blades, AdvancedMCs (AMCs) and rear transition modules (RTMs) • • • • • •

Cabinet: provides enclosure for shelves Cabinets can be interconnected to achieve more scalability. PDU: power feed from site power feed to shelf-level power modules Shelf: provides enclosure, cooling, power and HW management to blades and RTMs Blades (front boards): blades plug into the front side of the shelf. AMCs: advanced mezzanine cards plug into the AMC bay of a blade. RTMs (rear boards): rear transition modules plug into the rear of the shelf. RTMs are extension modules for blades.

Each blade and AMC in the network element works as a specific type of hardware node, with specific functionality and interfaces. Some nodes also include an RTM. The following diagram shows the different nodes as well as their main interfaces: ... AMC Carrier

Redundancy principles All switching, signalling and interface nodes use a 2N redundancy principle, where each active node is protected by a standby node which takes over if the active node fails. The TCU nodes have N:1 redundancy within a shelf. This means that each shelf has a single standby TCU node which takes over the processing tasks of any failing active TCU nodes. Node type

Overview of AHUB3-A The ATCA hub blade AHUB3-A is the main switch used for internal traffic between nodes in a network element and, by employing its Layer 3 capability, it can also be used for routing traffic to/from external networks. The hub blade provides connections for two types of networks: • •

Base interface (BI) switch for the network element’s internal traffic (for communication between computer nodes) Fabric interface (FI) switch for communicating with external networks as well as for the network element’s internal user data communication (for example, user data transmitted through AMC modules).

In addition, AHUB3-A provides management interfaces towards shelf manager through the base switch, and the hub can also be used for distributing a reference clock signal to other ATCA units (the signal can be either received from an external source or it can be generated locally).

Figure 23

AHUB3-A

The hub blade is a single-slot wide blade equipped in the two hub slots (slots 8-9) in the 16-slot ATCA shelf. Two hub blades are always required in one shelf for redundancy.

System manager The system manager is the central management application in the ATCA system, providing a user interface for accessing hardware-related information, such as configuration data and various logs and measurements. The system manager consists of software running on, for example, a redundant pair of CPU blades. The tasks of the system manager include: • • •

handling FRU state transitions, such as hot swaps and resets storing centralized information on events and alarms in the system storing FRU information

The system manager and the shelf manager are connected through the base interface, and communicate via IPMI commands. The system manager communicates with the shelf manager via IPMI commands encapsulated as remote management control protocol (RMCP) packets. As shelf manager is implemented with hardware platform interface (HPI) that is an abstract layer over RMCP and provides a platform-independent set of programmatic interfaces, the system manager can also communicate with the shelf manager via the commands developed by software platform. The communication between the system manager and the shelf manager can be based on: • •

remote management control protocol (RMCP) in case of OpenHPI daemon running on the system manager and RMCP server running on the shelf manager remote procedure call (RPC) protocol in case of IntegralHPI enabled on the shelf manager

If the simple network management protocol (SNMP) traps are enabled, the shelf manager sends events to the system manager. Otherwise, the system manager is not able to receive any event from the shelf manager directly. System manager is not part of the ATCA hardware platform. ATCA hardware platform offers only the hardware, the software platforms offer the software functionality.

Shelf manager The shelf manager controls all blades and other field replaceable units (FRUs) in the shelf through the intelligent platform management interface (IPMI). Each blade in the shelf has an IPM controller (IPMC) connected to the shelf manager’s shelf management controllers (ShMC) through a redundant intelligent platform management bus (IPMB0). AMC modules and rear transition modules contain a module management controller (MMC), which interfaces with the IPMC in the controlling blade. The ShMCs, IPMCs and MMCs together form the intelligent platform management (IPM) subsystem. Fan modules and power entry modules are connected to the shelf manager through a master-only I2C bus.

Blade management IPMC subsystem overview Each blade contains an Intelligent Platform Management Controller (IPMC) subsystem which provides the ability to monitor, query, and log system management events on the blade. The functions of the IPMC subsystem include controlling the blade state, power supplies, and LEDs, monitoring voltages and temperatures, logging events, and maintaining information on the blade. The IPMC subsystem consists of the following components: • • • • •

IPM Controller EEPROM Local voltage and temperature sensors Serial interfaces Power load control

The IPMC subsystem communicates with the shelf manager through the Intelligent Platform Management Bus (IPMB). It also stores a Local System Event Log (SEL) and Sensor Data Records (SDR) which can be used for troubleshooting purposes. In addition, the EEPROM contains a Field Replaceable Unit (FRU) information storage. The user can access the information stored in the IPMC subsystem through the system manager.

Sensor data records (SDR) The IPMC subsystem contains sensors for monitoring the payload power, voltages, or the general health of the field replaceable unit. The power sensors monitor all voltages of the IPMC power supplies. An alarm is raised if one of the values exceeds the allowed range. The temperature sensors monitor the temperature of the board and components, as well as the ambient temperature at the blade's backplane. Sensor data record may also contain information about the state of the FRU hot swap or software upgrade. The user can access the sensor data record through the system manager.

System event log (SEL) The system event log (SEL) stores all IPMI events, such as hot swaps and resets. This information can be used for troubleshooting. The SEL is stored in an EEPROM managed by the IPM controller. The SEL can log 447 entries. When it fills up, the oldest events are deleted. The SEL information is periodically sent to the system manager. The user can read the local SEL through the system manager.

RTM management A rear transition module (RTM) is managed through its front blade. The RTM and the blade are connected by the RTM's zone 3 connector. The front blade’s IPM controller (IPMC) connects to the RTM’s Module Management Controller (MMC) to handle the RTM operation, such as hot swap, LEDs, and sensors. The RTM contains an EEPROM for storing its own FRU information. The RTM also receives its power from the front blade.

FRU information repository All field replaceable units (FRUs) that contain a hardware management controller contain an EEPROM for storing information about the unit itself. This information storage is commonly referred to as a FRU information repository. The repository contains information on the firmware versions, addressing, connectivity, and configuration of the unit. This information can be viewed through the system manager or with shelf manager clia commands. For the shelf alarm display, shelf alarm panel and shelf data module of the 16-slot shelf, only identification information is available, and it is included in the shelf FRU information. Cabinets, PDUs, and cables do not have electronically stored FRU information.

Timing and synchronization in the 16-slot shelf

12 Timing and synchronization in the 16-slot shelf 12.1

Overview of timing and synchronization Synchronized clock signals are distributed to units within and across shelves by means of the timing and synchronization domain. The master frequency for a clock signal can be derived from various sources: • • •

SDH/Sonet line input External reference (SETS/BITS) Master clock generator (MCG) internal oscillator

Re-generating and distributing the clock signal within a network element is based on using master clock generators (MCG) in each shelf. Master clock generator (MCG) A 16-slot shelf always contains two master clock generators, one per hub blade. The master clock generators share signalling via the update channel in the shelf backplane to determine which is the primary (MCG1) and spare (MCG2) unit within the shelf at any given time. A master clock generator supports three clock modes: synchronized, holdover and freerun (internal). •

•

•

During normal operation, the MCG is locked to one of the references and operates in synchronized mode. In the synchronized mode, an automatic reference switchover is made upon reference failure. Recovery can be either revertive or nonrevertive. If all references become unavailable, the system clock enters holdover mode. This means that the frequency is kept very precisely at the best known frequency, based on previous frequency history. During start-up, or if information about past frequencies is not yet available, the system clock uses a factory-set frequency and is in free-run mode.

Shelf-level synchronization Within a shelf, the MCG1/MGW2 either receives a master clock signal from a BITS/SSU source or line interface, or uses its own oscillator to generate a clock signal. It then distributes the clock signal at 19.44 MHz and 8 kHz frequencies towards the rest of the units in the shelf via the backplane synchronization clock interfaces CLK1 and CLK2.

Shelf-level timing and synchronization interfaces

Cabinet-level synchronization A master clock signal arrives in the network element through a BITS/SSU cable port in a hub blade RTM in shelf 1, and is received by the MCG1/MGW2 in a hub blade. The re-generated signal is distributed towards other shelves through another BITS/SSU cable port in the hub blade RTM. The figure below presents a chain of synchronization signals: shelf 1 - shelf 2 - shelf 3. Another configuration option is a cable between shelf 1 and shelf 2, plus a cable between shelf 1 and shelf 3. Shelf 1 hub blade RTM can be provided more than one reference input for redundancy if considered necessary.The hub blade RTM can also be used as synchronization reference to external equipment. A single cable port includes one input and one output.
