IBM® xSeries 360: User’s Reference
The fans in the server can operate at variable speeds so that if one fan fails, the
remaining fans increase in speed to enable continued operation until the failing
fan is replaced. You can replace a failing fan without turning off the server.
The server supports up to three 370-watt power supplies. Multiple hot-swap 370-
watt power supplies ensure redundancy and hot-swap capability for a typical
configuration.
• Large system memory
The memory bus in the server supports up to 8 GB of system memory. The
memory controller provides error correcting code (ECC) support for up to eight
industry-standard, 2.5 V, 168-pin, 16-byte, PC1600 registered DDR SDRAM dual
inline memory modules (DIMMs). The memory controller also provides Chipkill
Memory protection. Chipkill Memory protection is a technology that protects the
server from a single chip failure on a DIMM.
• Light Path Diagnostics
Light Path Diagnostics provide LEDs to assist in isolating problems with the
server. An LED on the operator information panel is lit if an unusual condition or a
problem occurs. If this happens, you can look at the LEDs visible through a
special cutout in the cover and isolate the cause. Under some circumstances,
you may need to remove the cover and view LEDs on the system board to
pinpoint the source of a problem.
• Systems-management capabilities
The server comes with a Remote Supervisor Adapter installed. This adapter, in
conjunction with the systems-management software provided with the server,
enables you to manage the functions of the server both locally and remotely. The
Remote Supervisor Adapter also provides system monitoring, event recording,
and dial-out alert capability.
• Integrated network environment support
The server comes with an Ethernet controller integrated into the system board.
This Ethernet controller has an interface for connecting to 10-Mbps or 100-Mbps
networks. The server automatically selects between 10BASE-T and 100BASE-
TX. The controller provides full-duplex (FDX) capability, which enables
simultaneous transmission and reception of data on the Ethernet local area
network (LAN).
• Remote expansion enclosure
The addition of an optional, IBM RXE-100 Remote Expansion Enclosure provides
up to twelve additional hot-plug PCI/PCI-X slots for PCI or PCI-X adapters. The
enclosure can be managed through the Remote Supervisor Adapter, enabling
remote operation over a network or a modem.
• Redundant network adapter
The addition of an optional, redundant network adapter provides a failover
capability to a secondary Ethernet connection. If a problem occurs with the
primary Ethernet connection, all Ethernet traffic associated with this primary
connection is automatically switched to the redundant network adapter. If the
appropriate device drivers are installed, this switching occurs without data loss
and without user intervention.
• IBM ServerGuide™ CDs
The ServerGuide CDs that are included with the server provide programs to help
you set up the server and install the network operating system (NOS). The
ServerGuide program detects the installed hardware options and provides the
correct configuration programs and device drivers. In addition, the ServerGuide
CDs include a variety of application programs for the server.
