Abstract: In MxU V800R306C01, V800R307C00, and V800R307C01, the MxU control board fails after the following operations are performed: Product Line: Access […]
During a lab test for the SmartAX MA5616 V800R307C02, a service interruption has occurred due to an exception of the logic. The root cause, however, is not yet identified after more than three months of efforts to reproduce the issue in the lab. This prewarning notice describes how to identify this issue and restore the service. Product Line: Access network Product Model: MA5616 Problem Description Trigger conditions Use a SmartAX MA5616 V800R307C02 that is in full configuration of service boards in the test. Create a service port on each VDSL port, set up a point-to-point over Ethernet (PPPoE) connection on each service port, and send the packets. Import the configuration file to the device and activate the file multiple times, and then reset the system. Enable and disable the security function multiple times and then perform dynamic host configuration protocol (DHCP) dialup and PPPoE dialup multiple times. Symptom […]
Summary: In MA5616 V800R310C00SPC100 through V800R310C00SPH109, if the MA5616 uses an H.248 interface registered using a domain name, the MA5616 resource overload occurs after the MA5616 runs for a long period of time. Product Line: Access network Product Family: MxU Product Model: MA5616 Keywords: MA5616 resource overload Problem Description Trigger Conditions This issue occurs if the following conditions are met: The H.248 service has been configured on the MA5616. A softswitch domain name has been configured on an H.248 interface. The softswitch domain name is only used for checking an H.248 message head. The following figure shows an example.
Summary: When replacing the AC power board PAIA/PAIB on the MA5610/MA5616, if the operator removes the power board without powering off it beforehand (removing the 220 V AC power connector on the panel), there are potential safety hazards. Product Line: Access Network Product Model: MA5616 Keywords: MA5610/MA5616 PAIA PAIB AC power board security specifications Problem Description Trigger conditions When replacing of the AC power board PAIA/PAIB on the MA5610/MA5616, the operator removes the AC power board without powering off the board beforehand (disconnecting the 220 V AC power plug from the panel). Symptom Removing the power board before disconnecting the 220 V power plug from the board panel causes potential safety hazards. Identification method The MA5610s/MA5616s installed with the PAIA or PAIB power boards that are delivered to sites before September 1, 2009 […]
