1-10 System Overview

Peripheral Controller

The advanced integrated peripheral controller supports two serial ports, two universal serial ports, one parallel port, one diskette drive, PS/2-compatible keyboard and mouse, and integrated Real Time Clock (RTC). The system provides the connector interface for each port.

Serial Ports

Both serial ports are relocatable. Each serial port can be set to one of four different addresses and can be enabled separately. When disabled, serial port interrupts are available to add-in boards.

External Device Connectors

The rear panel external I/O connectors provide support for a PS/2 compatible mouse and a keyboard, for a SVGA monitor, serial port COM 1 connector, two LAN connectors, two USB connectors and an external SCSI wide connector. Serial port COM2 connector is located on the front panel of your server.

System Board Management Controller (BMC)

Server management is concentrated in the System Board Management Controller (BMC). The BMC and associated circuitry are powered from a 5Vdc standby voltage, which remains active when system power is switched off, but the ac power source is still on and connected.

The BMC supports the Management Workstation Application (MWA), which allows remote server management via a modem or direct connection to a manager system. Events monitored by the manager system include over-temperature and over-voltage conditions, fan failure, or chassis intrusion.

Information on MWA may be found on the ExpressBuilder CDROM included with your server.

One major function of the BMC is to autonomously monitor system management events, and log their occurrence in the nonvolatile System Event Log (SEL). The events being monitored include overtemperature and overvoltage conditions, fan failure, or chassis intrusion. To enable accurate monitoring, the BMC maintains the nonvolatile Sensor Data Record (SDR), from which sensor information can be retrieved. The BMC provides an ISA host interface to SDR sensor information, so that software running on the server can poll and retrieve the server's current status.

System Overview 1-11

ACPI

The BMC performs the following:

Monitors server board temperature and voltage

Monitors processor presence and controls Fault Resilient Boot (FRB)

Detects and indicates baseboard fan failure

Manages the SEL interface

Manages the SDR Repository interface

Monitors the SDR/SEL timestamp clock

Monitors the system management watchdog timer

Monitors the periodic SMI timer

Monitors the event receiver

Controls secure mode, including video blanking, diskette write-protect

monitoring, and front panel lock/unlock initiation Controls Wake On LAN via Magic Packet support.

The Advanced Configuration and Power Interface (ACPI) aware operating system can place the system into a state where the hard drives spin down, the system fans stop, and all processing is halted. However, in this state the power supply is still on and the processors are still dissipating some power such that the power supply fan and processor fans are still running.

Note: ACPI requires an operating system that supports its

feature.

CAUTION

Only when the AC power is disconnected is the system completely off.

Your server’s system BIOS supports sleep states s0, s1, s4, and s5. The sleep states are defined as follows:

s0: Normal running state.

s1: Processor sleep state.

No context will be lost in this state and the processor caches will maintain coherency.

s4: Hibernate or Sav e to Disk.

The memory and machine state are saved to disk. Pressing the power button or other wakeup event restores the system state from the disk and resumes normal operation. This assumes that no hardware changes have been made to the system while it was off.

1-12 System Overview

s5:Softoff.

Only the RTC section of the chipset and the BMC are running in this state.

AC Link Mode

The AC link mode allows the system to monitor its AC input power so that when the AC input power is lost and then restored the system will return itself to one of three preselected settings, listed as follows:

Power On

Last State (Factory Default Setting)

Stay Off.

The AC link mode settings can be changed by running the BIOS Setup Utility (F2). Refer to Chapter 3 "Configuring Your System."

Remote Power-On (Wake ON LAN) Function

The remote power-on function turns on the system power by way of a network or modem. If the system power is set to OFF, it can be turned on remotely by sending a specific packet from the main computer to the remote system. This feature can be enabled or disabled using the BIOS Setup Utility. See Chapter 3.

Note: This feature must be supported by your operating system.

System Security

To help prevent unauthorized entry or use of the system, the system i ncludes a full lockable front bezel and Server Management software that monitors the front bezel intrusion switch.

Security with Mechanical Locks and Monitoring

The front bezel contains a mechanical lock to prevent access to the computer chassis.

The BIOS Setup Utility provides a number of security features to prevent unauthorized or accidental access to the system. Once the security measures are enabled, access to the system is allowed only after the user enters the correct password(s). For example:

Enable the keyboard lockout timer so that the server requires a password to

reactivate the keyboard and mouse after a specified time-out period1to 120minutes.

Set and enable an administrative password.

Set and enable a user password

Set secure mode to prevent keyboard or mouse input and to prevent use of the

front panel reset and power switches. Disable writing to the diskette drive when secure mode is set.

Overview

This chapter describes how to select a site, unpack the server, install your rackmount server, make cable connections, and power your server.

Selecting a Site

The system operates reliably in a typical office environment. Choose a site that is:

Near grounded, three-pronged power outlets.

Note

: For the United States and Canada, this means a

NEMA 5-15R outlets for 100-120 VAC or NEMA 6-15R outlets for 200-240 VAC. For other international sites, this means three-pronged power outlets applicable for the electrical code of the region.

Be sure the power service connection is through a properly grounded outlet.

WARNING

CAUTION

When two power supplies are installed in the system the power plug from each of the power supplies must be plugged into the same common ground power outlets.

Clean, dust-free, and well ventilated. Front and rear ventilating openings

kept free of obstructions. Away from sources of heat, vibration or physical shock.

Isolated from strong electromagnetic fields and electrical noise produced

by electrical devices (such as air conditioners, large fans, large electric motors, radio and TV transmitters, and high-frequency security devices)

Easily accessible for system maintenance and installation of system

upgrades.
