Description
ACT
(green)
If the indicator is on, it indicates that the SFU is working normally; if the
green indicator is off, it indicates that the SFU is faulty.
OFFLINE
(red)
When the SFU is working normally, the OFL indicator is off. After the OFL
button is pressed to power off the SFU, the OFL indicator is on.
The CR5DSFUI407B can be used only on the NE40E-X16.
The 40G switch fabric unit cannot be used together with 200G switch fabric unit for long-term
working, and can be used together only for short-term operation during upgrade.
2.5 Control Plane
This chapter describes the control plane of the NE40E-X16.
2.5.1 Introduction to the Control Plane
This section describes the functions of the control plane.
The control plane of the NE40E-X16 is separated from the data plane and the monitoring
plane.
The MPU on the NE40E-X16 is responsible for system control and management, including
route calculation, device management and maintenance, and device monitoring.
System Control and Management Unit
As the system control and management unit, the MPU provides the following functions on the
system control panel:

Route calculation: All routing protocol packets are sent by the forwarding engine to the
MPU for processing. In addition, the MPU broadcasts and filters packets, and downloads
routing policies from the policy server.

Outband communication between boards: The LAN switch modules integrated on the
MPU provide outband communications between boards. In this manner, messages can be
controlled, maintained, and exchanged between SFUs and LPUs.

Device management and maintenance: Devices can be managed and maintained through
the management interfaces (serial interfaces) provided by the MPU.

Data configuration: The MPU stores configuration data, startup files, charging
information, upgrade software, and system logs.

Data storage: The MPU provides two interfaces for CF cards, which serve as mass
storage devices to store data files.
System Clock Unit
As the system clock unit, the MPU provides accurate and reliable SDH clock signals for
LPUs. The MPU can provide three-channel 2.048-MHz synchronous clock signals for the
downstream devices, or receive 2.048-MHz or 2.048-Mbit/s external reference clock signals.
