1. Housed in a 19in rack-mountable drawer and ships standard without a keyboard or mouse. See Rack Cabinets and Options section for supported IBM racks.
2. Intel Pentium III processor with advanced transfer L2 cache and 133MHz FSB.
3. Power supply redundancy requires installation of optional 270W Hot-Swap Redundant Power Supply (P/N 37L6880).
4. xSeries 340 includes two available removable media bays that can be converted to three slim-line (SL) hot-swap bays with the addition of optional 3-Pack
Ultra160 Hot-Swap Expansion Kit (P/N 33L5050), doubling internal hard disk drive storage capacity.
5. Assumes installation of optional IBM 3-Pack Ultra160 Hot-Swap Expansion Kit (P/N 33L5050) which converts the two available removable media bays into three
slim-line (SL) hot-swap bays.
6. Variable read rate. Actual playback speed will vary and is often less than the maximum possible.
