The installation has to be neet...no big loops of cable hanging >down from the ceeling...etc. We use thin Ethernet to connect about 275 workstations to their respective file servers (about 15 nodes per Ethernet). We've had few problems daisy chaining workstations. This includes installations within individual offices, and in the student labs. In the offices, we use plastic over the wall conduit to hide the coax, and in the labs, we encase it in Panduit. In an office, the incoming and outgoing coax ends just below the end of the conduit (and has BNC connectors). When you install a computer, you'll need to add extensions. When an office does not need a workstation, then you use a barrel connector to patch the incoming, and outgoing coax together. Depending on the nature of your users, this may not work. If your users like to connect and disconnect cables at will, and get into their hardware, you might appreciate the isolation that the multiport repeaters provide. (We also prefer Cabletron MR9000c's). If you do decide to daisy chain thin wire, you might want to consider investing in a GOOD time domain reflectometer. When you do have a problem, you will want to find it very fast because it will take several people down. Also, you'll want to be extremely picky about the quality of the cables you use. Dont even consider solderless connectors, or any cable other than RG58 A/U. (NOT RG58 /U !!!) -=- ______________________________________________________________________________ Dan Butzer - The Ohio State University, Dept of Computer & Information Science Net: butzer@cis.ohio-state.edu Voice: (614)292-7350 Snail: 2036 Neil Ave Mall, Room 245, Columbus, Ohio, 43210
