IBM ServerGuide™ CDs

The ServerGuide CDs that are included with your server provide programs to help you set up your 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 your server.

For more information about the ServerGuide CDs, see “Chapter 4. Using the ServerGuide CDs,” on page 21.

Reliability, availability, and serviceability features

Three of the most important considerations in server design are reliability, availability, and serviceability (RAS). The RAS features help to ensure the integrity of the data that is stored on your server, the availability of the server when you need it, and the ease with which you can diagnose and repair problems.

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

Automatic restart after a power failure

Customer support center 24 hours a day, 7 days a week1

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, optional redundant array of independent disks (RAID) configuration, 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

1. Service availability will vary by country. Response time will vary depending on the number and nature of incoming calls.
