Working Principle

ZXR10 5900E series products cassette fast Ethernet switches de-
veloped by ZTE. This series switches adopt modular design and
have strong capability in service control and user management so
as to provide networking solutions to convergence of enterprise
network, IP MAN network and residential block. ZXR10 5900E
series products have powerful functions and sound performance.
According to system functions, the product contains the follow-
ing modules: control module, switching module, interface module,
power module and monitoring module.
1. Control module: the module contains main processor and
some other external function chips and is used by system to
process various applications. It provides console port for data
manipulation and maintenance.
2. Switching module: the main part of switching module is packet
processor, used for processing and switching of packets sent
from ports;
3. Interface module: interface module is composed of interface
chip and corresponding peripheral circuits, mainly used for
connection to external users and packet forwarding.
4. Power module: the module adopts 220V AC and supports 1+1
backup and hot-swap to supply needed power to the other
components within the system.
5. Monitoring module: Supporting 3 dry node signal input and 5
dry node signal output.
