H801SCUN is a control board for the MA5600T and uses the BCM56820 LAN switch chip. After the hardware of the BCM56820 LAN switch chip is upgraded (that is, the BCM56820 LAN switch chip of a new hardware version is used), the software of the H801SCUN board needs to be changed accordingly. It is learnt that from Mar. 2010, the H801SCUN board to be delivered will use the LAN switch chip of Ver.B. In this case, if the software version of the H801SCUN board is earlier than V800R006C02SPC110, the H801SCUN board will fail to start. Sub-product line: Access Product: MA5600T Problem Description Trigger condition: In terms of the H801SCUN board (the LAN switch chip used is of Ver.B) to be delivered from Mar. 2010, 1. If you downgrade the H801SCUN board to a version earlier than V800R006C02SPC110, the H801SCUN board will fail to start. 2. If you delete the patch of V800R006C02SPC110, the H801SCUN board fails to start. Problem phenomena: When the H801SCUN board fails to start, the following information is displayed: Transferring control to the loaded program…OK! Starting system application init……successfully! […]
Digest: The H805ADPD, H805VDMF, H805VDRD, and H80ASHLM boards of MA5600T product need to be upgraded because their DDR1 memories are changed. Such a change is for customers using these boards. Sub-product line: Access network Product: MA5600T Problem Description 1.Product Engineering Code Change 2.Change Strategy 1) Change Scope: The sites with H805ADPD,H805VDMF,H805VDRD,H80ASHLM boards 2) Change relation : The new boards are produced with new DDR1 memories, all the function and performance are the same ,the BOM is the same too. The boards current used in sites won’t be effected. 3) Change finish date : H805ADPD:2010-12-31.Huawei will use old DDR1 memories to product board to deliver before 2010-12-31, and please push the related office to upgrade the corresponding IO board package files and software patches as soon as possible .We will deliver the new board after 2010-12-31, and won’t be permitted to deliver the boards if the office didn’t upgrade the corresponding patches. H805VDMF, H805VDRD, H80ASHLM:2010-9-30, please push the related office to upgrade the corresponding IO board package files and software patches as soon as possible. 3. Spare part Strategy The new board as spare part […]
The Issue that the MA5600T H802GPBD Board Resets Repeatedly Summary: In MA5600T V8R6 and V8R7, during the management message (OMCI and PLOAM messages) interaction when the H802GPBD board is connected ONUs, there is a possible that the CPLD logic bug is triggered. As a result, the board resets. Product Model: MA5600T Product Family: Optical access [Issue Description] Trigger conditions: ONUs are in the auto-discovery stage and the management message interaction increases. ONUs repeatedly go online and offline, and the management message interaction increases. ONUs are repeatedly powered on and powered off, and the management message interaction increases. The possibility of board reset increases with the normal management message interaction. Fault symptom: The H802GPBD board resets at random when it is connected to ONTs. Identification method: a. Query the CPLD version of the H802GPBD board. MA5600T(config)#display version 0/12 Send message for inquiring board version successfully, board executing… Main Board: H802GPBD […]
Summary: A running MA5600T may reset after the ping -v command is executed. Sub-Product Line: Access network Product Family: Optical access [Problem Description] Trigger conditions: The gateway returns an ICMP Destination Unreachable message after the ping -v IP address command is executed on an MA5600T. Fault symptom: The program instruction is abnormal and the MA5600T resets. See the following example: MA5600T(config)#ping -v 10.10.10.1 PING 10.10.10.1: 56 data bytes, press CTRL_C to break ======================== Exception Info Begin ======================== Exception Time : 2011-02-10 16:26:51 Exception VosTick : 10636031 Exception CpuTick : 0x00000674 8b463a54 Exception Type : PROGRAM EXCEPTION Exception Vector Num : 0x700 Exception Task : Co0 (ID = 98, OsalID = 0x783c020) Exception PID : -1 […]
Abstract: Some OLT GPON CLASS B+ optical modules provided by SOURCE PHOTONICS may rarely become faulty after long-term working at high temperature, resulting in unstable transmit optical power, and ONUs being offline. Product Line: Access network Product Family: OLT Product Model: MA5600T, MA5603T, MA5680T, and MA5683T [Problem Description] Trigger conditions: Optical modules have been working at the temperature higher than 60 degrees for a long term. Optical modules are OLT GPON CLASS B+ optical modules of the SPS4348HHPCDE model provided by SOURCE PHOTONICS. When the above conditions are met, 0.143% of the optical modules may have unstable transmit optical power, resulting in offline ONUs. Symptoms: Optical modules have unstable transmit optical power, resulting in offline ONUs. Identification methods: Method 1 If the ONU that connects to the PON port on a GPBD board is offline, perform the following steps to check whether the cause is the involved optical module in the warning. Check whether the optical module is working at high temperature and belongs to the […]
