Reliability, availability, and serviceability features

Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These factors help to ensure the integrity of the data stored on
the server; that the server is available when you want to use it; and that should a
failure occur, you can easily diagnose and repair the failure with minimal
inconvenience.
The following is an abbreviated list of the RAS features that the server supports.
v Menu-driven setup, system configuration, RAID configuration, and diagnostic
v Power-on self-test (POST)
v ROM resident diagnostics
v Integrated System Management Processor
v Predictive failure alerts
v Microprocessor built-in self-test (BIST), internal error signal monitoring,
v Diagnostic support of ServeRAID
v Cable detection
v Hot-swap drive bays
v System error logging
v Upgradable BIOS, diagnostics, and system management code
v Automatic restart after a power failure
v Parity checking on the SCSI and PCI buses
v Error checking and correcting (ECC) memory
v Redundant hot-swap power supply option
v Redundant hot-swap cooling
v Redundant Ethernet capabilities (with optional adapter)
v Vital Product Data (VPD) on processor complex, system board, power backplane,
v Operator information panel and group of diagnostic LEDs on the system board
v Remind button to temporarily turn off LEDs for nonvital alerts

Hardware Maintenance Manual: xSeries 342 Type 8669
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 associated with this primary
connection is automatically switched to the redundant NIC. This switching occurs
without data loss and without user intervention.
The addition of an optional digital linear tape drive (DLT) allows quick backup of
large amounts of data.

CDs
The ServerGuide CDs 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 hardware options installed, and provides the correct
configuration programs and device drivers. In addition, the ServerGuide CDs
include a variety of application programs for the server.
