Quidway® S8500 LSBM1SRP
Main Control Board Series
Overview
The LSBM1SRP main control board series is the switching route processing board of
Quidway®S8500. It can make configuration management and status monitor for entire
system and has the clock processing function. The board provides data switch and route
protocol processing function between Line Processing Unit (LPU) boards, implements the
across-board forwarding of service data and implements the centralized switching of
system. Each S8500 device should be configured with one main control board at least.
Two main control boards are recommended for redundancy protection. At present,
LSBM1SRP main control board provides five types: LSBM1SRP1N0, LSBM1SRP1N1,
LSBM1SRP1N2, LSBM1SRP1N3 and LSBM1SRP1M0.
As the core of S8500 route switch, LSBM1SRP switching route processing board provides
the following functions:
1. Implement such functions as switching, route protocol processing, equipment
management control and monitor, and clock processing.
2. Use 1+1 backup and 1:1 load sharing design, realize auto protection switchover and
ensure the uninterrupted system running.
3. Monitor the environment and state, including the state of temperature, fan and power,
and controls the rotation speed of each fan.
4. Provide a standard IDE interface, which can be inserted into CF card (Compact
Flash Card) to provide data storage capability for system (the capacity of CF card is
256 Mbytes by default, which can be expanded as required).
5. Back up the CF card and FAT table through NVRAM to save the configuration data of
user.
6. Provide the running indicator for Line Processing Units (LPUs) for the front panel,
which provides the running information of system vividly for user.
7. Provide multiple management interfaces such as 10/100M Ethernet port and RS232
serial port, have an independent management channel for each LPU board and
provide uniform management and maintenance for system.

8. Provide level 3 clock function and external clock interface through the clock pinch
board, provide level 3 clock reference for LPUs in the system and lock the interface
extraction clock provided by LPU.
Specifications
The LSBM1SRP main control board series provides the following interface externally:
AUX interface
The AUX interface uses an RJ-45 connector. The interface can serve as a backup
interface for the Console port to connect a background terminal, or directly connect a
Modem device, for remote system debugging, configuration, maintenance and
management. It can also connect the background terminal computer.
Attributes Description
Connector RJ-45
Standard Asynchronous EIA/TIA-232
Service Connects a serial port of a PC (through a Modem pair for a
remote PC) and runs terminal emulation on the PC.
Console interface
This Console interface uses RJ45 connector, which can be used to connect the
background terminal for debugging, configuring, maintaining, managing the system and
loading the host software program.
