SBC 7000 Series Hardware Platform Specifications

 

This section provides information on the Ribbon 

hardware platform specifications.

SBC 7000 Series Hardware Platform

The

 chassis consists of the mechanical enclosure, internal backplanes, fan modules and power supply modules that provide the infrastructure required to implement the  hardware platform. The 5U mechanical enclosure provides six rear facing slots used to install the platforms components.

The bottom two slots have dedicated functions: the System Controller Card (SCC7000) module and Core Server Card (CSC7000) module. The SCC slot (bottom slot) contains the SCC module used for chassis management and Processing (also known as BMC Baseboard Management Controller). The slot 0 (above SCC slot) contains the CSC module used for Control and Data plane processing. The top 4 slots (1-4) are used for optional specialized hardware modules, the first released module being the DSP-LC high capacity transcoding resource module. The CSC7000 and SCC7000 cards, monitor and control the chassis environment and operation.

Chassis

The Ribbon

 is contained in the 5U rack-mounted chassis. It can be front or center mounted in a standard 2 or 4 post 19” or 23" wide rack.

The

 chassis is made up of five major functional blocks:

• SBC 7000 5U Chassis
• CSC7000 Core Server Card
• SCC7000 System Control Card
• Fan Controller Modules
• Power Subsystem

Front Panel

The

 front panel consists of following modules:

• A front Bezel on which the various ports and LEDs are located
• ESD Strap Connector
• Two Solid State Disk bays
• Fan Assembly

The figure below shows the front panel LEDs with and without Bezel mounted on the front panel of the 

.

 

The table below lists the

 Front Chassis LEDs. Each LED is controlled by GPIOs on the SCC7000s AST2400 processor. The default state of all LEDs are during a reset.

The next table below lists the

 Chassis Switches. The status of switch is monitored via GPIOs on the SCC7000s AST2400 processor.

Fan Control Module

The

 chassis provides connections for 4 independent fan controller modules. Each consists of a pair of fans controlled by a Maxim MAX6616 dual fan controller and AT24C64 FRU EEPROM. In addition, the fans are powered directly by -48V using a -48V to +12V isolated DC to DC power converter. The MAX6616 and FRU EEPROM are controlled by the SCC7000 via a dedicated I2C bus and are powered by the chassis +3.3 volt standby supply.

Rear Panel

The

 rear panel consists of following modules:

• Two Earth Ground Terminals
• ESD Strap Connector
• Dual Power Supplies - two options
  • Dual 180-240 V AC
  • Dual -48 V DC
• System Controller Card (SCC7000) or BMC
• Core Server Card (CSC7000)
• Unable to show "metadata-from": No such page "_space_variables"
   DSP-LC (Large Capacity)

 

Power Sub-System Module

The main source of power for the

 chassis originates from redundant AC or DC power feeds. In the AC case, the chassis will be powered by 2 independent external 220 VAC power sources via 2 Hi-Line compatible AC inlet filter/connectors. The SCC7000 will route each AC power feed to a dedicated power supply which will then generate -48 V DC. Each supply will be capable of powering the maximum chassis configuration. When two supplies are installed, their outputs will be wire-ORed, allowing them to load share.

BMC System Control Card (SCC7000)

The SCC7000 card provides both the Baseboard Management Control (BMC) functionality as well as the Lights Out Management (LOM) functionality for the

 system.

The SCC7000 card is responsible for the low level hardware management of the

 system. The functionality supported by the SCC7000 card are:

• System fan management and power
• BIOS/Firmware upgrades
• System power management
• Front Panel LED management

The SCC7000 can be accessed via a dedicated Ethernet interface and a dedicated RS-232 interface.

 

The following tables describe each component of the SCC7000 panel.

Core Server Card (CSC7000)

The Core Server Card (CSC7000) provides the control and data plane processing resources required by the Ribbon Session Border Control application. The control plane processing functional block is responsible all activities related to session management. This includes calls/sessions setup/tear down, media interface management, encryption services, etc. The data plane functional block is responsible for providing data switching functionality for the traffic packets received and sent through the CSC7000 card.

The CSC7000 cards contains a total of 8 x Small Form Factor Interfaces (SFP/SFP+):

• 2 x Management Ports: Two GigE Ethernet ports (RJ-45, SFP-LC-MM, SFP-LC-SM)
• 4 x Media Ports: Four 10Gbps Ethernet fiber (SFP-LC-MM, SFP-LC-SM)
• 2 x High Availability Ports: Two 10Gbps Ethernet fiber (SFP-LC-MM, SFP-LC-SM)
