How to configure the MA5683T GPON&EPON start instructions part2

EPON:
Huawei OLT
1、Configure Upstream
vlan 100 smart   \\Add network management vlan
vlan 1001 smart   \\Add PoC vlan
Add the corresponding vlan to the uplink：
port vlan 100 0/6 0
port vlan 1001 0/6 0
Configuration management address：
interface vlanif 100
 ip address 192.168.10.100 255.255.255.0
2、Configuration DBA template
dba－profile add profile-id 10 type2 assure 20480
3、Configure line template
ont-lineprofile epon profile-id 10 profile-name HG8240
llid dba-profile-id 10
commit
4、Configure PoC template
ont-srvprofile epon profile-id 11 profile-name HG8240
ont-port eth 4 pots 2
Note: Must be based on the ONT actual number of port configuration，if you don't know it，you can enter the Epon veneer mode using the command "disp ont capability" view.
port vlan eth 1 100
commit
5、Add ONT equipment
intface epon 0/0
port 1 ont-auto-find enable
disp ont autofind 1
ont add 1 0 mac-auth 0000-0000-0001 oam ont-lineprofile-id 10 ont-srvprofile-id 11
Designate ONT port default vlan
ont port native－vlan 1 0 eth 1 vlan 1001
6、Configure PoC virtual port
service-port vlan 1001 epon 0/0/1 ont 0 multi-service user-vlan 1001

If in the fttb networking，Olt side only need to configure the line template, do not need to configure PoC template，add onu use snmp protocol。

Huawei ONU
1、Configure Upstream
vlan 1001 smart
port vlan 1001 0/0 1
2、Configure PoC port
service-port vlan 1001 adsl 0/0/30 vpi 0 vci 35 rx-cttr 6 tx-cttr

Some Abnormal OLT GPON CLASS B Part2

Method 2

Use the SMARTKIT inspector to query all optical modules. Manually collect information about vendor PN, transmit optical power, and enclosure temperature in the query results, as shown in Figure 2.

Characteristics of the involved optical module: The temperature is higher than 60 degrees, the transmit optical power is not in the range from 1.5 dBm to 5 dBm, the vendor PN is SPS4348HHPCDE, and the vendor is SOURCE PHOTONICS.

Information collection in the query results

Select the two check items as shown in the Figure 3.

Inspection template configuration

[Root Cause]

Some optical modules may rarely become faulty after long-term working at high temperature, resulting in unstable transmit optical power.

[Impact and Risk]

When the problem occurs, corresponding ONUs are offline. According to the vendor, 0.143% of the optical modules may become faulty at high temperature.

[Measures and Solutions]

Recovery measures:

Perform the following steps to cool the enclosure of the involved optical module.

Tune down the temperature in the equipment room.

If dust on fans or subracks results in weak heat dissipation capacity, urge customers to clear the dust. For details, customers can refer to corresponding product documentation, such as the MA5600T&MA5603T V800R011C00 Product Documentation 03.

Manually accelerate the rotating speed of fans. (Long-term high-speed rotation shortens the useful life of a fan, so this solution is just a temporary solution.) Setting examples are as follows:

For V800R005/V800R006/V800R007/V800R008:

MA5600T(config)#interface emu 0 

MA5600T(config-if-fan-0)#fan speed mode manual 

MA5600T(config-if-fan-0)#fan speed adjust 5

For V800R009/V800R010/V800R011/V800R012:

MA5600T(config)#diagnose 

MA5600T(diagnose)%%fan speed mode manual 6

The digit in red in the command indicates the rotating speed level of the fan (the highest levels for V800R008 and V800R011 are 5 and 6 respectively), the higher the digit, the faster the rotating speed. It is recommended to tune up the rotating speed to the maximum, and then gradually tune it down. Long-term high-speed rotation shortens the useful life of a fan. Therefore, exercise caution when adopting this solution.

Preventive measures:

Use the preventive maintenance inspection tool to check the enclosure temperature of optical modules on the live network. For the site where the enclosure temperature of optical modules is higher than 60 degrees, urge customers to improve equipment room environment. The recommended temperature is about 23 (±1) degrees.

Solution:

When the problem occurs, perform the recovery measures to cool involved optical modules, and then perform the following steps based on actual situations:

If the problem is solved, the optical module can be used but not used at high temperature.

If the problem persists (the hardware of the optical module is faulty), use a spare part to replace it. A small number of faulty optical modules can be directly sent to Huawei for repair based on the specified procedure. A large number of faulty optical modules are handled by corresponding regional service contact personnel.

[Warning Conditions]

The warning does not take effect when the trigger conditions are not met.
