in the server enables continued operation if one of the fans fails. The server
comes with one 550-watt or 750-watt hot-swap power supply and four fans.
You must install the fourth and sixth fans when you install the second
microprocessor in the server. You can order the second optional power supply for
power redundancy.
Note: You cannot mix 550-watt and 750-watt power supplies in the server.
v ServeRAID support
The ServeRAID adapter provides hardware redundant array of independent disks
(RAID) support to create configurations. The standard RAID adapter provides
RAID levels 0, 1, and 10. An optional RAID adapter is available for purchase.
v Systems-management capabilities
The server comes with an integrated management module II (IMM2). When the
IMM2 is used with the systems-management software that comes with the server,
you can manage the functions of the server locally and remotely. The IMM2 also
provides system monitoring, event recording, and network alert capability. The
system-management connector on the rear of the server is dedicated to the
IMM2. The dedicated system-management connector provides additional security
by physically separating the management network traffic from the production
network. You can use the Setup utility to configure the server to use a dedicated
systems-management network or a shared network.
Reliability, availability, and serviceability
Three important computer design features are reliability, availability, and
serviceability (RAS). The RAS features help to ensure the integrity of the data that
is stored in the server, the availability of the server when you need it, and the ease
with which you can diagnose and correct problems.
Your server has the following RAS features:
v
3-year parts and 3-year labor limited warranty for machine type 7914
v Automatic error retry and recovery
v Automatic restart on nonmaskable interrupt (NMI)
v Automatic restart after a power failure
v Backup basic input/output system switching under the control of the Integrated
Management Module II (IMM2)
v Built-in monitoring for fan, power, temperature, voltage, and power-supply
redundancy
v Cable-presence detection on most connectors
v Chipkill memory protection
v
Diagnostic support for ServeRAID and Ethernet adapters
v
Error codes and messages
v
Error correcting code (ECC) L2 cache and system memory
v
Hot-swap cooling fans with speed-sensing capability
v
Hot-swap hard disk drives
v
Information and light path diagnostics LED panels
v
Integrated Management Module II (IMM2)
v
Menu-driven setup, system configuration, and redundant array of independent
disks (RAID) configuration programs
v
Microprocessor built-in self-test (BIST), internal error signal monitoring,
configuration checking, and microprocessor and voltage regulator module failure
identification through light path diagnostics
v
Memory mirrored channel support (memory mirrored channel are mutually
exclusive of each other)
