Quidway® MA5200G-2 System Management Unit (SMUC)
Overview
The SMUC is the System Management Unit board of MA5200G-2. It is the simplified board of the
SMU, only applicable to MA5200G-2. The SMUC board integrates three major functional modules,
main control module, data switch module and stratum-3 clock module. It mainly implements such
global functions as access user management, authentication charging, route processing, resource
management, state monitor and network management agent. It provides system stratum-3 clocks.
MA5200G-2 has three slots. Only has one slot for SMUC card. Because A5200G-2 is a compact
high rate of cost performance product, no redundant backup of system management card is
provided.
The outer appearance of the SMUC is shown in the following.
Specifications
On the MA5200G-2 SMUC four external interfaces are provided: CONSOLE port (communication
serial port), AUX port (auxiliary communication serial port), 10/100/1000BASE-TX Ethernet port
and four stratum-3 clock coaxial ports.

Interface Type 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.
SMUC
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.

Interface Type Description
Ethernet port(RJ45)
It is a 10/100/BASE-TX Ethernet port. It uses RJ45 connector,
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 device.
Stratum-3 clock coaxial port
Each SMU board has a system clock module. The panel has
four coaxial connectors. Where, two input ports are used to
connect the BITS clock and two output ports output 2048 KHz
or 2048 Kbps clock to the downstream device.
