First of all, let's introduce the function module components of Metro1000 V3 equipment. Let you first have a certain understanding of the various functional modules of Huawei SDH equipmentMetro1000V3 equipment.The SCB system control module of OptiX 155/622H Metro1000V3 equipment integrates the functions of line, branch, crossover, clock, time, master control, and public affairs, etc. The following is an introduction to the functions of the SCB board in different modules.

Line Module: It provides 2 optical interfaces of STM-1 or STM-4 or STM-16; the STM-1 optical interface is called OI2D, the STM-4 optical interface is called OI4D, and the STM-16 optical interface is called OI16D. The STM-1 optical interface provides the optical interfaces of S-1.1, L-1.1, and L-1.2 types, and it uses the SC/LC type connector; the STM-4 optical interface provides S-4.1, L-4.1, and L-4.2 types, and it uses the SC/LC type connector. 4 optical interface provides S-4.1, L-4.1, L-4.2 type optical interface using SC/LC type connector. STM-16 optical interface provides S-16.1 type optical interface using LC type connector. Provides two synchronized clock sources for the clock unit. With ALS (Automatic Laser Shutdown) function.
Spur Module: Spur Module: Provides access to 16-channel E1 signals. Supports the E1 asynchronous mapping method defined in ITU-T G.703, mapping E1 asynchronously into the VC-12 virtual container. Provide two types of interfaces, 75Ω unbalanced and 120Ω balanced, with interface characteristics that meet the requirements of the indicators in ITU-T G.703 recommendations. Handles VC-12 channel overhead, configures, alarms and monitors the performance of each service channel, and communicates with the master control unit. Provides internal/external loopback function, which can test the quality of E1 service or find the fault point for easy maintenance. Provides a synchronized clock source for the clock unit.

Crossing Module: Supports VC-4/VC-3/VC-12 level cross connection, which can realize service scheduling between line to line, line to branch, and branch to branch. The supported high-order cross-capacity is 21.25G, and the low-order cross-capacity is 5G.

Public Affairs Module: Provides one way public affairs telephone, supports conference call and broadcast function. Provides four RJ-45 type RS-232 serial data interfaces to support point-to-multipoint device connection and transparent transmission of user data. Provide 4 input and 2 output switching interfaces. The input switching quantity is mainly used for monitoring the status of external devices, and the output switching quantity is mainly used for outputting alarm instructions and controlling external devices.

Problem Description

The NO_BD_SOFT alarm does not normally occur during normal operation of Metro1000V3 devices, and it basically occurs after the device host is upgraded.

Alarm Information

NO_BD_SOFT is a single board without software alarm (Software file corrupted or missing). This alarm indicates that there is no software required by the single board, or the name of the single board software is wrong.

Alarm Parameters:

When browsing alarms in the network management, select the alarm, and the related parameters of the alarm will be displayed in the "Alarm Details". The format of alarm parameter is "Alarm Parameter (hexadecimal): Parameter 1 Parameter 2...Parameter n", such as: Alarm Parameter (hexadecimal): 0x01 0x08.... See the following table for a description of the meaning of each parameter:

Parameter 1 Fixed to 0x01, meaningless.

Parameter 2 and parameter 3 represent the type of file missing from the software of the single board, and the value range is different for each single board.

Parameter 4 and 5 are reserved.

Impact on the system:

If the veneer software does not exist on the veneer or the veneer software name is wrong, reset the veneer and the veneer will not start. Generally two sets of host software will be switched to run under the normally running host software.

Processing

First, focus on the third parameter to confirm which specific file of the host can not pass the test.

Para [3] indicates the location of the missing file

0x11 indicates that the file /ofs1/hwx/nesoft.hwx is missing.

0x12 Indicates that the file /ofs1/hwx/ne.ini is missing.

0x13 means /ofs1/fpga/eow.pga file is missing.

0x14 Indicates /ofs1/fpga/xc_stg.pga file is missing.

0x15 Indicates /ofs1/fpga/xc_ts.pga file is missing.

0x17 means /ofs1/hwx/extbios.hwx file is missing.

0x21 means /ofs2/hwx/nesoft.hwx file is missing.

0x22 means /ofs2/hwx/ne.ini file is missing.

0x23 means /ofs2/fpga/eow.pga file is missing.

0x24 Indicates /ofs2/fpga/xc_stg.pga file is missing.

0x25 Indicates missing /ofs2/fpga/xc_ts.pga file.

Second, delete the missing or incomplete files by ::sftm-delete-file command.

For example::sftm-delete-file:11,"/ofs1/fpga/eow.pga";

Third: Copy another complete software package over with the :sftm-copy-file command.

:sftm-copy-file:11,"/ofs1/hwx/ne.ini", 11,"/ofs2/hwx/ne.ini";

Fourth, reset the host via the Reset command.

Five, if after the above operation or NO_BD_SOFT, that itself host FLASH chip storage of the host software in the region of physical failure, can only be solved by replacing the SCB.

Sixth, the process of upgrading, to be two sets of host software, extended BIOS, FPGA all six files loaded after the proposed use of :sftm-show-dir command to check the two sets of ofs/hwx (fpga) directory of the file size is the same.

Root Cause

Since the host will periodically check the integrity of the host software, extended BIOS, and FPGA of the two sets, if any of the files in the two sets are found to be incomplete and cannot pass the verification, the NO_BD_SOFT alarm will be reported.
