IBM Asia Pacific Hardware Announcement AG11-0009 IBM is a registered trademark of International Business Machines Corporation 22Supported memory optionsThe following memory options are supported:• 2GB (2Gb, 1Rx8, 1.35V) PC3L-10600R ECC LP RDIMM (49Y1405)• 4GB (2Gb, 1Rx4, 1.35V) PC3L-10600R ECC LP RDIMM (49Y1406)• 4GB (2Gb, 2Rx8, 1.35V) PC3L-10600R ECC LP RDIMM (49Y1407)• 8GB 2Rx4 2Gbit PC3L-10600R LP RDIMM 1.35V Capable (49Y1397)• 8GB 2Rx4 2Gbit PC3L-8500R LP RDIMM 1.35V Capable (49Y1398)• 16GB (2Gb, 4Rx4, 1.35V) PC3L-8500R LP RDIMM (49Y1400)• 2GB (1x2GB, 2Rx8, 1.35V) PC3L-10600 CL9 ECC DDR3 1333MHz LP (49Y1392)RDIMM• 2GB (1x2GB, 1Rx4, 1.35V) PC3L-10600 CL9 ECC DDR3 1333MHz LP (49Y1393)RDIMM• 4GB (1x4GB, 2Rx4, 1.35V) PC3L-10600 CL9 ECC DDR3 1333MHz LP (49Y1394)RDIMMPower supply requirementsThese models contain one 920-watt power supply, which is a hot-swap capablesupply. When not using redundancy, one hot-swap supply has enough power tosupply a fully loaded box. If redundancy is required, you should install additionalpower supplies to ensure sufficient power will be available. A fault light illuminateswhen a power supplies fails.Optional rack installationsThese models are optionally installable as rack units and are designed so they canbe installed in an industry-standard 19-inch rack cabinet such as the NetBAY42or NetBAY25. The x3500 M3 server system requires a rack mount kit for rackinstallation. In addition, it can also be installed in the deeper NetBAY42 ER.If you choose not to use an IBM rack, the cabinet must meet EIA-310-D standardsfor mounting flanges and hole clearances with front to rear mounting of 70 - 73cm (27.5 - 28.5 in). The rack must provide sufficient room in front of the forwardEIA flange to allow for bezel attachment. The standard for 310-D suggests 49 mm(1.9 in) clearance. It must also provide adequate room at the rear of the rack,behind the rear flange for cable management; the System x3500 M3 server requiresapproximately 16.6 cm (6.5 in) in this space.The rack should include perforated front and rear doors and must not prevent theflow of cool air into or out of the rack. The weight handling capacity of the rack is22.7 kg (50 lb). Finally, the rack must provide proper stabilization so that the rackdoes not become unstable when servers are pulled out of service.Cable ordersDual Broadcom 5709C 10/100/1000 Mbps, full-duplex Ethernet PCI controllers,standard with the x3500 M3 server, are connected directly to two independent RJ-45connectors. The RJ-45 connectors provide a 10BaseT, 100Base-TX, or 1000Base-TXinterface for connecting twisted-pair cable to the Ethernet network. Cabling is notincluded with the server. To connect the Ethernet controller to a repeater or switch,use a UTP cable with RJ-45 connectors at both ends. For 100/1000 Mbps operation,Category 5 cabling must be used. For 10 Mbps operation, Category 3, or better,cabling must be used.There are no additional cabling requirements, other than for system power,keyboard, mouse, and monitor connections.
