Our libraries have one fiber cable per tape drive, and two lan cables. The lan cables are for the specialist web interface. One lan cable plugs into the lan port in the first frame. The other plugs into the lan port of a node card in one of the other frames that has drives. You can assign IP numbers to these lan ports via the front panel. > > As for internally, how does the library talk to the drives/canisters?

It has a internal bus connects to the drives with the controllers. This allows you to power cycle a drive, load microcode, etc. >My understanding is there is a fibre patch-panel in each D-frame to > which you connect 2m cables to the drives and then I guess to connect the > fibre cables from the SAN switch to this same patch-panel? Exactly. Each drive has two fibre ports. Both ports have cables to a patch panel at the bottom of a frame. You connect from the patch panel to your switch. I really wish I > had the "maintenance manual" for the 3584! If you haven't already, download these manuals: TS3500 Introduction and Planning Guide. (lots of gory details) Redbook: IBM TotalStorage Tape Libraries Guide for Open Systems The full maintenance manual comes with the library. IBm has it stashed in the back of one of the frames. So it's probably in the boxes from IBM . . . go hunting! ----------------------------------------- The information contained in this message is intended only for the personal and confidential use of the recipient(s) named above.
