    66== Serial Console physical setup ==

    8 In the MF/PL Telehouse rack, we have installed two [http://www.lavalink.com/index.php?id=232 Octopus 550's] in `sylvia`, a domU that is installed on `octavia`. An Octopus 550 is a pci card that has 8 serial lines coming out of it. `octavia` already has two built-in serial lines. `octavia`'s first built-in serial line is outputting the console for `octavia` itself. The second built-in serial line is reserved (it will probably be used to control a power system). The remaining 16 serial lines are connected to other servers in our rack.
     8In the MF/PL Telehouse rack, we have two 8 port USB to serial adapters using the pl2303 chipset `robideau`.
