N2000BMS shows the alarms with an early hour because the NE does not have configured the right time zone

Issue Description

The alarms displayed in the N2000BMS are displayed with an early hour.
The alarm is reported in the OLT MA5600V800R007
Example:
the next alarm is reported in Huawei MA5600T at 01:39:49-05:00, but, in the N2000BMS appear the same alarm at 02:39:49. The time in the N2000BMS is the real time.

Handling Process

Because of the BMS had the correct time, so, it was supposed that the DST was not configured in the NEs.
It was analyzed the time settings and the time zone  in Huawei OLT.

Ceylan(config)#display time                                                  
{ <cr>|dst<K>|time-stamp<K> }:                                                 

  Command:                                                                   
          display time                                                       
  2011-11-02 10:10:03-05:00                                                                                                                                 
Ceylan(config)#display timezone                                              
The current time zone:  GMT-05:00
it was found that the timezone is not the correct. So it was requested change the timezone to make a test.

After modify the time zone to the correct one, the alarms was reported in the N2000BMS with the correct time.
However, to avoid changing the timezone every period of time, it was suggested to enable the DST.

Ceylan(config)#display time dst                                              
  Failure: DST has not been configured  
  

Suggestions

Verify the timezone of the country to set the correct one in the NE or in the Server. Also, consider use the DST feature.

Huawei MA5800- X17 Appearance and Structure

Huawei MA5800-X17 service subrack provides 22 slots,while Huawei MA5600T has 16 service solt and has a fan tray at the top. The subrack is installed in the cabinet through the mounting brackets.

ESD Jack
The ESD jack of Huawei MA5800-X17 subrack is on the left of the fan tray, which is used to
connect the ESD wrist strap to prevent device damage caused by electrostatic discharge.

Connect the ground cables properly to guarantee protection against lightening and
interference for the MA5800-X17 subrack. When a Huawei cabinet is installed, the service
subrack is grounded through mounting ears and therefore no separate ground cables are
required. When a third-party cabinet is installed, the separate ground cable needs to be
connected to the service subrack and ground point on the cabinet.

the bottom of the right mounting ear of the subrack.
The power input end of the MA5800-X17 subrack has a noise filter. The center ground of the
noise filter connects to the subrack, called the subrack ground, that is, the protection ground.

Ground the subrack securely so that the influence electricity, leakage electricity can flow to
the ground, improving the protection against electromagnetic interference.
Use a ground cable to connect the ground point of the subrack to the ground bar of the
telecommunications room or to the ground directly. It is recommended that the grounding
resistance of the telecommunications room should be less than 10 ohms. Refer to the local
standards to ground the subrack.

Dimensions and Weight:
Dimensions (H x W x D, including mounting ears):486 mm x 535 mm x 287 mm
Dimensions (H x W x D, excluding mounting ears):486 mm x 493 mm x 287 mm

Why can not log in BMS system after V200R011C01B037 BMS newly added the northbound interface components?

Issue Description

When manage Huawei MA5600T, can not log in BMS system after V200R011C01B037 BMS newly added the northbound interface components, why?

BMS version: iManager N2000 BMS V200R011C01B037
Because we didn't choose the northbound interface components at the first installation, the northbound process can't be started and the function can't be usefully. But the northbound function is necessary to the customer, so we have to newly add the northbound interface components. After installed the components, we can't log in the BMS system and the error is "The license file has been overdue".

Alarm Information

Try to log in the BMS system, the error is "The license file has been overdue".

Handling Process

The process is as follows:
1. The BMS is only installed for three days and the probationary period is 90 days;
2. Before the installation of northbound interface components, the system can be logged in successfully. The installation aroused the problem;
3. The installation of new BMS components will update the old license in the system. The error  indicated the new BMS license isn't working, so we think the update has some problems;
4. We checked the updated license file and find it's much bigger than normal license file;
5. Copy other normal license to overlay the error license;
6. Re-start the BMS system, we can log in successfully.

Root Cause

The installation of new BMS components will update the old license in the system. The error information indicated the new BMS license isn't working, so we think the update has some problems.
The BMS version iManager N2000 BMS V200R011C01B037 has the problem. If the problem appeared, we have to copy other normal license to overlay the error license to solve the problem.
