SBC 5000 Series Customer Replaceable Units

Ribbon provides replacement units to the customer, who then performs the installation for these replacement units. For CRU information and replacement instructions, refer to SBC 5000 Series CRUs. 

SBC 5110 and 5210 CRUs

Equipment Requirement	Description
Fan Assembly	Three cooling fan assemblies located behind the front bezel.
Solid State Drive	Solid State Disk (SSD) storage located behind the front bezel.
Air Filter	Located within the front bezel assembly, filters the cooling air.
SFP	Single or Multi mode fiber transceivers and Copper SFPs (which functions like a plug) used for Gigabit Ethernet connections to Media ports and HA ports. Connect to LC-connector on the SFP side and SX-module on the other end of the connection to L3 switch.
Bezel	Secures replaceable air filter to front of chassis and identifies LED status indicators.
DSP20	Signal Processing Cards (plug-in module with a low capacity DSP card).
DSP25	DSP25 Signal Processing Cards (plug-in module with a high capacity DSP card).
Power Supply	Up to two DC or two AC power supply modules accessible from the rear of the chassis. Caution Switching to a different power supply voltage type (AC to DC, or DC to AC) requires that the system be powered down first.

DSP2x Signal Processing Cards for SBC 5110/5210

This is the second generation Signal Processing Server (SPS) for SBC 5000 series and provides increased signal processing capabilities over the earlier SPS100 card by incorporating the latest DSP technology. It is an add-on module that can connect to SBS100 motherboard through a 150-pin connector.

The DSP2x cards contain the actual DSP processing resources. There are two DSP2x module variants supported: DSP20 and DSP25. SBC 5110 has four slots which provides maximum capacity. The cards are hot swappable and installable/replaceable in the field. The DSP20 has 1/5 the density of the DSP25. While inserting DSP25 cards, fill the slots in order - slot 1, 2, 3, 4.

For more information on DSP2x module, refer CRU documents SBC 5x10 DSP20 Module and SBC 5x10 DSP25 Module. For more information on DSP Channel densities for each SBC 5x10 series, refer to SBC 5x10 DSP Densities.

FPGA Reprogramming for DSP2x Module

The DSP2x module includes a Field-Programmable Gate Array (FPGA) that may occasionally require reprogramming. The reprogramming is fully autonomous and occurs during system reboot process. The only noticeable effect to the system is a slight increase to the duration of the system reboot. For each DSP2x installed, expect an additional 1-2 minutes added to the length of a normal reboot process.

Log messages pertaining to FPGA reprogramming are stored in the following files:

• sbx_start.log_(timestamp) file is located in /var/log/sonus/sbx/openclovis directory. This file contains all logs related to system startup as well as a log of other scripts that call this FPGA reprogramming utility.
• /var/log/messages file.
