Service processing capabilities

• 
  
• The MSPB0 adopts one multi-core processor, which is designed in the multi-core, multi-line structure.
• The MSPB0 uses two 4 GB DIMMs, with a total memory capacity of up to 8 GB.
  

• Interfaces

  • Two Base interfaces (10/100/1000M BASE-T Ethernet interfaces)
  • Two Fabric interfaces (1000M BASE-B Ethernet interfaces)
  • One Update interface (2.5 Gbit/s SerDes x 4 Ethernet interface)
  • One debugging interface
  • Six SerDes interfaces are provided for connecting to the RPUA back board.
  
  

• Management functions

  The MSPB0 provides a BMC module with independent power supply. The BMC module connects to the SMM through the IPMB bus with redundancy configuration.

  The BMC module performs the following functions:

  • Managing the information about the Field Replaceable Unit (FRU), Sensor Data Record (SDR), and System Event Log (SEL)
  • Monitoring the temperature, voltage, and reporting alarms
  • Controlling the hot-swap, power-on, power-off, and reset of the board
  • Supporting online software loading
  • Supporting Serial Over LAN (SOL)
  
  

• Integration capabilities

  • Dual-channel gigabit Ethernet controller
  • Intelligent Platform Management Interface (IPMI)
  
  
• Supporting hot swapping

7. HEALTHY indicator	8. OOS indicator	9. Ejector lever

An ejector lever is located on the upper side of the front
panel and on the lower side of the front panel. You can use the ejector
levers to insert, remove, power on, and power off the MSPB0 board.

Table 1 describes
the instructions for using the ejector levers to insert and remove the board.

Table 1 Inserting and removing the board using the ejector levers

Operation	Description
Inserting the board	When inserting the board, pay attention to the following: Before you lower the ejector levers, the HOTSWAP indicator is on, indicating that the board is not powered on. After you lower the ejector levers, the HOTSWAP indicator blinks at long intervals, indicating that the board is being activated. After the board is successfully powered on, the HOTSWAP indicator turns off.
Removing the board	When removing the board, pay attention to the following: When you raise the ejector levers, the HOTSWAP indicator blinks at short intervals, indicating that the board is being deactivated. The board is ready for power-off after successful deactivation. When the HOTSWAP indicator turns on, indicating that the board is powered off, you can remove the board.

Table 2 describes the instructions for using the ejector levers to power on and power off the board.

Table 2 Powering on and powering off the board using the ejector levers

Operation	Description
Powering on the board	When you lower one or both ejector levers, the board is powered on and starts operating.
Powering off the board	When you raise both the ejector levers simultaneously, the board is powered off.

documentation very useful for my job

Really very sound doc please share more like this..........

Yes you are right MSPB0 uses two 4 GB DIMMs, with a total memory capacity of up to 8 GB. Thanks

Very useful........
