Packetshaper 12000 requires 8.6.3 or above to boot. If the PacketShaper is unable to boot successfully due to an improper image version, you must revert to the backup image of PacketWise, which is the image previously installed on the unit before you loaded the recent image.
The recovery procedure must be performed from a console connection:
- Using a null-modem cable, attach a workstation or PC to the unit’s port labeled CONSOLE. This cable offers both 9 pin and 25 pin connectors on each end.
- Start your terminal emulation program (such as HyperTerminal).
- Verify that you have configured the program with the following values to communicate with the unit’s console serial port:
• 9600 bps, 8 data bits
• 1 stop bit
• no parity
• hardware flow control
Note: If you are using a modem connected to the serial port, the modem must be set to: 9600 bps, 8 data bits, 1 stop bit, no parity, auto-answer (usually ATH1 in the standard Hayes command set), and DTR always on (usually a DIP switch setting). Check the modem manual for details.
- Power cycle the PacketShaper.
- As the unit is attempting to boot, (the message Loading... appears in your terminal emulation program), press Ctrl+B. This forces the PacketShaper to reboot using its backup image.
