Below we propose a design for fiber connections between the Rack Room and the Hall, and network switch and terminal server placement.

Notes
- Based on 10**8 photons/sec, 200 kHz trigger rate, existing L1 rejection algorithm, block=1 mode, no compression.
- Ethernet port counts from Fernando's rack layouts and information from Dave Butler concerning other controls requirements.
- We own about 15 24-port managed switches with 10 GBit/s fiber uplinks.
- 8-port managed switches with 1 GBit/s fiber uplinks exist.
- Only managed switches (no hubs!) allowed in hall.
- Fibers come in bundles of 12 or 24, 2 fibers needed for one uplink.
- Standard JLab practice is to terminate all fibers in patch panel when bundles installed.
- DAQ crates require two Ethernet connections each, one for the ROC and one for the fan tray.
- ROC's each need an RS232 connection to a terminal server, terminal servers require an Ethernet connection.
- Each terminal server has xxx ports.
- other stuff...
