Power supply requirements
These models contain one 920-watt power supply, which is a hot-swap capable
supply. When not using redundancy, one hot-swap supply has enough power to
supply a fully loaded box. If redundancy is required, you should install additional
power supplies to ensure sufficient power will be available. A fault light illuminates
when a power supplies fails.
Optional rack installations
These models are optionally installable as rack units and are designed so they can
be installed in an industry-standard 19-inch rack cabinet such as the NetBAY42
or NetBAY25. The x3500 M3 server system requires a rack mount kit for rack
installation. 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 standards
for mounting flanges and hole clearances with front to rear mounting of 70 - 73
cm (27.5 - 28.5 in). The rack must provide sufficient room in front of the forward
EIA 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 requires
approximately 16.6 cm (6.5 in) in this space.
The rack should include perforated front and rear doors and must not prevent the
flow of cool air into or out of the rack. The weight handling capacity of the rack is
22.7 kg (50 lb). Finally, the rack must provide proper stabilization so that the rack
does not become unstable when servers are pulled out of service.
Cable orders
Dual Broadcom 5709C 10/100/1000 Mbps, full-duplex Ethernet PCI controllers,
standard with the x3500 M3 server, are connected directly to two independent RJ-45
connectors. The RJ-45 connectors provide a 10BaseT, 100Base-TX, or 1000Base-TX
interface for connecting twisted-pair cable to the Ethernet network. Cabling is not
included 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.
