IBM XSERIES 220 Reliability, availability, and serviceability, Server controls and indicators

•System-management capabilities

System-management software is included with the server to manage the functions of the server locally and remotely. Refer to the documentation that comes with the system-management software for more information.

•Integrated network environment support

The 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 environments. The controller provides full-duplex (FDX) capability, which allows simultaneous transmission and reception of data on the Ethernet local area network (LAN).

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

Reliability, availability, and serviceability

Three of the most important considerations in server design are reliability, availability, and serviceability (RAS). The RAS factors help to ensure the integrity of the data that is stored on the server, the availability of the server when it is needed; and the ease with which problems can be diagnosed and repaired.

The following is an abbreviated list of the RAS features that e server supports:

•Automatic restart after a power failure

•Cyclic redundancy check (CRC) checking on the small computer system interface (SCSI) buses

•Diagnostic light-emitting diodes (LEDs)

•Error checking and correcting (ECC) memory

•Error codes and messages

•Menu-driven setup, system configuration, redundant array of independent disks (RAID) configuration (optional), and diagnostic programs

•Optional system-management adapter subsystem to provide control for remote system management

•Optional Wake on LAN® (WOL) function through network-interface card (NIC adapter)

•Power and temperature monitoring

•Power-on self-test (POST)

•Processor serial number access

•System error logging (POST)

•Upgradeable basic input/output system (BIOS) and diagnostics

•Vital product data (VPD) on memory, system board, and hot-swap drive backplane
