File Servers and Download Process
The download process from the file servers is as follows:
1 The username required to connect to the FTP/SFTP enabled servers is provided in the instruction file.
The password required to connect to the servers is same as the username.
2 The required files mentioned in the instruction file are downloaded from the primary FTP/SFTP file
server.
3 If the configuration, debug and script file names are specified in the instruction file, then they are
downloaded to the /flash/working directory of the switch.
4 The Remote Configuration Manager now compares the current firmware version on the switch to the
one mentioned in the instruction file. If the firmware version is different, then firmware upgrade is
performed.
5 The new firmware or image files are downloaded to the working directory of the switch.
6 All the required files are downloaded.
7 Now, the DHCP client configured on the related VLAN is removed.
8 The script file is downloaded and the commands in the script file are run. All the commands in the
script file are implemented on the switch in the order specified.
For other detailed steps that are part of the automatic remote configuration download process, see
“Automatic Remote Configuration Download Process” on page 13-10
LED Status
The LED status during different stages of the Automatic Remote Configuration download process is as
follows:
• DHCP phase: OK1 LED is flashing green
• DHCP lease obtained: OK1 LED is solid green
• DHCP phase stopped by console login: OK1 LED is solid green.
• Automatic Remote Configuration in process: OK1 LED is flashing amber.
Note. If the primary server is down or if there is any failure in downloading the files from the primary file
server, then a connection is established with the secondary file server. The secondary file server is used for
file download.
Note. If a specific filename (for firmware and configuration/debug/script files) is not found, an error is
logged. The download process continues with the next available file. File transfer is tried three times and if
file transfer still fails, an error is logged, and download process is stopped. In such instances, the working
folder of the switch will contain an incomplete set of image files, configuration, debug, or script files. For
details on troubleshooting under such instances, see “Nearest-Edge Mode Operation” on page 13-17.
