I upgraded the GC to new firmware version using MON2020. After successfully upgrading, GC rebooted automatically and could't completely start and is unable to communicate with PC after that.
LED's on the front panel are all OFF.
While LED's on backpane are all green.
LED's on CPU and I/O board are blinking green
Can anyone explain? and how much time it takes to be normal after this reboot.
