FRUs are replaceable units typically replaced by authorized service personnel.
The following table lists the SBC 5200 and SBC 5100 Field Replaceable Units (FRUs).
Equipment Requirement | Description |

Sonus provides replacement units to the Customer, and the Customer performs the installation for these replacement units. For CRU information and replacement instructions, refer SBC 5000 Series CRUs.

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.
Only one DSP20 is allowed in SBC 5x10 chassis, and it must reside in slot 1.
Mixing DSP20 and DSP25 cards (both within a chassis and between Active/Standby servers) is not supported. For example, if SBCa contains DSP25 in slots 1-3, SBCb should have a DSP25 in slots 1-3. As another example, if SBCa has a DSP20 in slot 1, SBCb should not have anything other than a DSP20 in slot1.
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:
