H3C AR 46 Series Routers  Installation Manual 

Chapter 7  Troubleshooting

 

Terminal emulation: VT100  

Reconfigure the parameters if their values are different. 

7.3  Troubleshooting Application Image Upgrade 

Symptom 1: 

Start the router and upgrade Comware software using TFTP. The console screen 

displays:  

DownLoad Program To Flash Through Net Port  

boot device          : ErrDev  

unit number          : 0  

processor number     : 0  

file name            : AR46.bin  

inet on ethernet (e) : 1.1.1.1  

host inet (h)        : 1.1.1.2  

user (u)             : user  

ftp password (pw)    : password  

flags (f)            : 0x80  

 

Loading... Loading Failed 

Solution:

 

Fault occurs because an incorrect boot device ErrDev is selected.  

Change ErrDev to the application upgrade device of the AR 46 series: wancom if an 

RPU is used or eth0 if an ERPU or ERPU(H) is used. 

Symptom 2: 

Start the router and upgrade the application image using TFTP. The console screen 

displays: 

DownLoad Program To Flash Through Net Port  

boot device          : wancom  

unit number          : 0  

processor number     : 0  

file name            : AR46.bin

host inet (h)        : 1.1.1.2  

user (u)             : user 

ftp password (pw)    : password  

flags (f)            : 0x80  

 

Attached TCP/IP interface to wancom0.
