Specifications

-Physical access to the BSC's serial console port.
-A nine pin null-modem serial cable.
-A laptop running a terminal emulation application such as Microsoft HyperTerminal.
Components Used
The information in this document is based on these hardware and software versions:
-BSC-600/1200 running any software image.
-A laptop running a terminal emulation application such as Microsoft HyperTerminal.
In summary we will access the BSC via the serial console port. Using a laptop running a terminal
emulation application such as Microsoft HyperTerminal we will attempt to interrupt the boot
process to get to a CFE> prompt where we can manually switch partitions. If we can successfully
boot to the alternate partition we can then perform an upgrade. The upgrade is applied to the
alternate partition so it will repair the original partition. For further info on upgrades see BSC
software upgrade documentation.
1. Start with the BSC powered off. Connect a laptop with a nine-pin null-modem serial cable to
the BSC's serial console port. Use a terminal emulation program such as Microsoft
HyperTerminal (9600,8,none,1,none).
2. Power on the BSC. Immediately begin to press control-c repeatedly until the interrupt in the
boot process stops at a CFE> prompt. There is only a 2-3 second time frame for the interrupt
from the time BSC is powered on.
3. Assuming the current runtime is "A" perform the following to switch to the "B" partition:
-At the CFE> boot prompt type setenv -p BSYS B then enter (setenv -p BSYS A to boot from
the A partition)
-Then type reset -sysreset -yes then enter
-This will boot to the "B" partition. If your current runtime is B, replace B with an A in the
setenv command.
4. If you can successfully boot to the alternate partition you can then perform an upgrade. The
upgrade is applied to the alternate partition so it will repair the original partition. For further info
on upgrades see BSC software upgrade documentation.
My Certificate Authority requires a 2048 bit Certificate Signing Request (CSR). How can I
generate a 2048 bit CSR on the BSC?
