GGSN Startup Sequence
� 1. The SRU board startup first.
� 2. The SPU/LPU startup
� 3. The DMPU (Daughter Mutil-purpose Process Unit )
startup after the related SPU startup.

Version Software Package Usage� The *.cc file is a compressed file and is stored in the hard disk of SRU.
� The *.cc file contains software packets of all boards. When a board starts up, it
downloads its software packets from SRU board to its memory.

Configuration Recovery
� After the SRU starts up, the configuration management
module reads configuration commands from the
configuration files and then recover the configuration
one after one.
Copyright © 2010 Huawei Technologies Co., Ltd. All rights reserved. Page26
� In the configuration files, the commands related to
interfaces cannot run immediately. The commands are
stored and start to run after the corresponding interface
board successfully registers.

can use the BootRom menu to check or change the SRU IP.
Configure the FTP Server
� A. Copy the software to FTP server
� The host software files are saved in the directory D:\GGSN9811 of
the FTP server (LMT). If you store the software in other directory,
you should set that directory as the working directory of FTP user.
� The *.XML files are description files for the host software version.
When you upload the host software, these three files must be
