3 Software Downloading Failure Fault

3.1 Description of Fault

I. FTP client login failure
OMC sends a command to an OMU (a base station operation & maintenance unit
running on BCKM) to start downloading files from BAM. The OMU receives the
command, but cannot log on to the FTP server of BAM. In this case, OMC
background receives the abnormal halt message of OMU and FTP client login fails.
II. Abnormal halt of file loading by the board
When some board software is downloaded and activated by means of OMC, it is
found that the whole stage from the starting of downloading and activating to the
waiting for the activation report is normal. Then, OMC receives the abnormal halt
message of OMU and file loading is abnormally halted by the board.

3.2 Fault Analysis and Location

I. FTP client login failure
1)
Check whether the FTP server on BAM is in Stop status or correctly set.
First view whether the FTP server is in Stop status. If it runs normally, then check
whether the FTP server is set correctly. FTP server settings include the following four:
user name, user password, user accessible path and access authority. Any setting
error will lead to failed login or failed board software loading.
When a base station loads software, the above four items are set as follows:
User name:
Password:
Access path:
Access authority:
2)
Check whether OMU BOOTP is normal
OMU obtains the IP address of a base station by means of BOOTP request. If this
process fails, OMU will not be able to obtain the IP address of the base station and
naturally cannot log on to the FTP server of BAM. Usually, a disconnected link, wrong
route or configuration data error may lead to the failed BOOTP process. These should
be eliminated one by one. For details, please refer to "5.1 OML Signaling Fault".
II. Abnormal halt of file loading by the board
All load files must have the file headers in stipulated format, in which the file ID and
file version must be consistent with the corresponding field in the activation command
sent by OMC. Otherwise, the board will consider the software actually downloaded as
inconsistent with that to be loaded and reports abnormality error.
