[cisco-nas] 7206 PPPoE NAS crashed

[Souphonh Phounsavath]

Dear All,

 

I am using 7206, which has specs as describe below:

 

System image file is "disk0:c7200-js-mz.124-3.bin"

 

Cisco 7206 (NPE225) processor (revision A) with 245760K/16384K bytes of
memory.

Processor board ID 10860270

R527x CPU at 262MHz, Implementation 40, Rev 10.0, 2048KB L2 Cache

6 slot midplane, Version 1.3

 

4 Ethernet interfaces

2 FastEthernet interfaces

2 Serial interfaces

125K bytes of NVRAM.

 

62976K bytes of ATA PCMCIA card at slot 0 (Sector size 512 bytes).

4096K bytes of Flash internal SIMM (Sector size 256K).

Configuration register is 0x2102

 

I am using it as PPPoE NAS. It operated only for about 27 days, and then
crashed. The power is still on, but I cannot access to the box via console
or FastEthernet port. However, when I switch off the power and switch on
again, the box can operate normally. I am not sure what the source of the
problem is. Anyone has ideas about it? The following is router's
configuration:
