provides a full 500 watts of power. If the average load
on your server is less than 250 watts and a problem
occurs with one of the power supplies, the other power
supply can handle the load (redundant power). If the
average load on your server is greater than 250 watts,
and you have installed a second power supply, you can
install a third, optional power supply to provide
redundancy.
The OVERCURRENT light emitting diode (LED) on the
system board is lit when the power load is 250 watts or
greater with two power supplies, or when the power load
is 500 watts or greater with three power supplies.
v Large system memory
The memory bus in your server supports up to 4 GB of
system memory. The memory controller provides error
correcting code (ECC) support for up to four industry
standard PC133, 3.3 V, 168-pin, 8-byte, registered,
synchronous-dynamic-random access memory (SDRAM)
DIMMs (Intel PC-Registered SDIMM Specifications,
Revision 1.0 or later), synchronous, dual inline memory
modules.
v System-management capabilities
Your server comes with a Netfinity Advanced System
Management Processor on the system board. This
processor, in conjunction with the Netfinity Manager
™
provided on your ServerGuide CDs, allows you to
manage the functions of the server locally and remotely.
The Netfinity Advanced System Management Processor
also provides system monitoring, event recording, and
dial-out alert capability.
Note: The Netfinity Advanced System Management
Processor is sometimes referred to as the service
processor.
Refer to the Advanced System Management section for
more information.
v Integrated network environment support
Your server comes with an Ethernet controller on 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 allows simultaneous transmission and
reception of data on the Ethernet local area network
(LAN).
v Redundant network-interface card
The addition of an optional, redundant network interface
card (NIC) provides a failover capability to a redundant
Ethernet connection. If a problem occurs with the
primary Ethernet connection, all Ethernet traffic
