Figure 1-10 illustrates the working principles of the MA5616 chassis.
Figure 1-10 Working principles of the MA5616 chassis
The working principles of the MA5616 chassis are as follows:
l The control board transmits services upstream and subtends device through subboards andmanages service boards.
l The power board outputs DC power to the backplane and then the backplane transmits thepower to the fan tray, service boards, and control board.
l The broadband or narrowband service board is connected to a user-side device by using asubscriber cable, and then the control board puts the user-side device through to the IPnetwork. In this way, broadband or narrowband access service is provisioned to the user-side device.
l The fan monitoring board monitors the fan tray and transmits the monitoring signal to thecontrol board through the backplane.
1.7 Heat DissipationThe MA5616 chassis provides a fan tray that houses a fan monitoring board and fans for heatdissipation.
Function
The fan tray of the MA5616 chassis provides the following functions:
l Heat dissipation: The fan tray is located in the left part of the MA5616 chassis and blowsair to dissipate heat for the chassis. The cool air flows into the chassis from the left andthen flows out from the right of the chassis after passing the boards.
l Monitoring: A fan monitoring board is configured in the fan tray. The fan monitoring boardchecks whether the fans are functioning properly, provides a port for communicating withthe control board, and periodically transmits the monitoring information to the controlboard.

l Speed adjustment: The fan tray automatically adjusts fan speed according to thetemperatures detected by temperature sensors on all boards and the traffic volume on thevoice service boards.
Ventilation
The fan tray, which is in the left part of the MA5616 chassis, houses fans to blow air for heatdissipation.
The ventilation of the MA5616 chassis is as follows: Cool air enters the chassis from the leftside, and then flows towards the right side, and finally exits from the right side.
Figure 1-11 illustrates the ventilation of the MA5616 chassis.
Figure 1-11 Ventilation of the MA5616 chassis
Appearance
The fan tray used by the MA5616 chassis houses two fans. Figure 1-12 shows the appearanceof the fan tray.

Silk Screen Description
FAN Steady green The fan tray functions properly.
Steady red The fan tray is abnormal.
Fan Speed Adjustment Mode
Fans in the fan tray of the MA5616 chassis have the following modes:
l Self-check mode: Fans start running at full speed when the device is powered on for thefirst time or is reset. After fans start up, the duty ratio of fans is initialized.
l Troubleshooting mode: Fans run at full speed and related alarms are reported when faultsoccur.
l Board-based fan speed adjustment mode: According to the temperatures detected bytemperature sensors on all boards and the traffic volume on the voice service boards, fansautomatically adjust their speed.
Figure 1-13 shows the status transfer of the fans after the fan tray starts up.

The H835CALE board can be divided into two parts: the broadband part and the narrowbandpart. The basic working principle of the board is as follows:
l The protection module protects and isolates the board from lightning strikes.l Broadband service processing:
– The broadband interface module converts the ADSL2+ line signals into cell flows.– The logic processing module implements functions such as encoding/decoding, analog-
to-digital conversion, and line driving for ADSL2+ services. It also provides anupstream port connecting to the UTOPIA bus of the backplane.

l Narrowband service processing:– The narrowband interface module provides access to 32-channel narrowband services.– The narrowband service control module controls and manages narrowband services.– The codec module encodes and decodes voice signals and converts analog signals into
digital signals. It also provides an upstream port connecting to the HW bus of thebackplane.
l The splitter module couples broadband and narrowband subscriber lines and separatesPOTS signals from ADSL2+ signals.

4.1 EPS30-4815AF Power SystemThe AC-powered cabinet uses the EPS30-4815AF power system to convert the AC input intothe DC power for power distribution.
FunctionThe EPS30-4815AF power system converts one AC input into two DC outputs to implementthe DC power distribution. It can be connected to one set of batteries and use its monitoringmodule to manage the batteries.
The EPS30-4815AF power system can also use the external sensor transfer box to collect andreport the status of sensors and standby detected parameters.
NOTE
The rectifier modules of the EPS30-4815AF power system work in the load balancing and mutual hotbackup mode.
