hello ccr users
I am a person who operates ccr device in Korea.
I had an embarrassing job on February 2, 2018,
I would like advice from an experienced ccr'man.
1) Overview
I lost 10ea ccr-1009 and 1ea ccr-1016 at the same time on 2018.02.02.
The ccr devices i have been running for a year or two have all been down at the same time with the same phenomenon.
There is no connection to the ccr devices afterwards.
I could not physically initialize my ccr devices but could not connect it.
2) What appears on the screen
When initializing by connecting an RS-232 cable,
The screen contents are as follows.
"
Ethernet link absent ---
trying bootp protocol --------------------------------------------------------
------------------------------------------------------------------------------
----------------------------------------------------------------------- failed
kernel loading failed
RouterBOOT booter 3.33
CCR1009-7G-1C
CPU frequency: 1000 MHz
Memory size: 1024 MiB
NANO size: 128 MiB
Press any key within 2 seconds to enter setup -
loading kernel ... kernel not found or data is corrupted
Please, check ethernet cable ...
"
3) Actions
(1) Device-specific initialization ---> Not accessible
(2) Replace PowerSupply -> No effect
(3) Replace all of them with alternative ccr device and analyze the cause
Look forward to your wise advice
