Quidway®ME60-8 Main Process Unit（MPUB）
Overview
MPUB is the main process and switching board of ME60-8, implementing such global functions as
route processing, service processing, resource management, state monitor, network management
agent and data switching. The main control board is inserted in the MPU slot of ME60-8 backplane
frame. Redundant configuration can be used to realize hot backup. When two MPUBs and two
switching network boards are used together, the ME60-8 can realize 3+1 redundant configuration of
the switching module.
ME60-8 has 12 slots in total: two main control slots, two switching network board slots and eight
service line card slots. Each ME60-8 needs to be configured with one or two MPUBs. Two MPUBs
are recommended. It can realize redundant backup of main control board and improves the system
reliability.
The outer appearance of MPUB is illustrated in the following.
Specifications
On the MPUB of ME60-8 five external interfaces are provided: CONSOLE port (communication
serial port), AUX port (auxiliary communication serial port), 10/100/1000BASE-TX Ethernet port, CF
card interface and system clock input/output interface.

name Interface Description
CONSOLE
port (RJ45)
It is a communication serial port, using RS-232 level. This Console
port is used to connect the background terminal for debugging,
configuring, maintaining, managing the system and loading the host
software program.
MPUB
AUX port
(RJ45)
It is an auxiliary communication serial port, using RS-232 level. The
AUX port is used to connect the MODEM device. It implements
remote configuration, maintenance and management through
dial-up.

Module
name Interface Description
Ethernet port
(RJ45)
It is a 10/100/1000BASE-TX Ethernet port. It uses RJ45 connector
with ACT and LINK indicators, connecting the background terminal,
for loading and debugging program. Moreover, the system can
connect the devices such as remote network management
workstation through the interface and realize the remote
management of equipment.
CF card
interface
It is used to insert the Compact Flash (CF) card. As the mass
storage device, the CF card is used to store the system
configuration information and alarm log.
System clock
input/output
interface
Each MPUA board has a system clock module. The panel has four
coaxial connectors. Where, two input ports are used to connect the
BITS clock input and two output ports output 2048 KHz or 2048
Kbps clock to the downstream device.
