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 Xeon processor with integrated full-speed ECC L2 cache and 100 MHz access to memory and I/O buses.
3. xSeries 370 includes a systems management adapter equivalent to the one shipped with option 01K7209 (Netfinity Advanced System Management PCI
Adapter).
4. Variable read rate. Actual playback speed will vary and is often less than the maximum possible.

1. xSeries 370 architecture optimizes memory and bus performance using a 100MHz, five-port crossbar core chipset. Up to eight Pentium III Xeon processors are supported on two
100MHz P-6 CPU buses. The recommended order of processor installation is: Sockets A1, A3, A2, A4, B1, B3, B2, B4.
2. Up to seven additional processors may be installed, providing a maximum of eight. All processors must be identical in type, speed, and cache size. The fifth through eighth
processors require a Netfinity Mezzanine Expansion Kit (P/N 10K2337).
3. Requires removal of the standard processor(s). A maximum of eight processors may be installed. Installation of greater than four processors requires the addition of a mezzanine
board and two cache coherency filters. Required options which provide the board and filters vary by model. For more information refer to “Processor Upgrade Requirements.” All
processors must be identical in type, speed and cache size. Upgrades may require a BIOS update. To obtain the latest Flash BIOS, access www.pc.ibm.com/support and enter
machine “Type-Model” in Quick Path. Select “Downloadable files” and then “BIOS.”
4. The fifth through eigth processors require this option. See “Processor Upgrade Requirements” for more information on when this option is required.

1. This table does not address the processor part numbers required. It does address the optional Enablement Kit, Filters, and Mezzanine Board part numbers required. 900MHz
processors can be substituted for 700MHz processors in this table.
2. All processors must be identical in type, speed, and cache size. Upgrades may require a BIOS update. To obtain the latest Flash BIOS, access www.pc.ibm.com/support and
enter machine “Type-Model” in Quick Path. Select “Downloadable files” then “BIOS.”
3. Remove the standard processor mezzanine board.
4. Remove all optional Enablement Kit components.
5. Remove Enablement Kit mezzanine board. The Enablement Kit 4X cache coherency filters are supported for use with Netfinity Mezzanine Expansion Kit (P/N 10K2337).
