However, rooms with humidity over 70%, and dusty or dirty areas are not appropriate. In addition, do not expose the system to any temperatures over +35° C or under +10° C. Make sure that the cables connecting the system to peripheral devices are not tight. Make sure that all power and connection cables are positioned so that they are not trip hazards. When you save data to your system`s hard disks or to a floppy disk, they are stored as magnetic information on the media. Make sure that they are not damaged by magnetic or electromagnetic fields. Because the electronics in your computer can be damaged by jarring, no mechanical devices should be placed on the same surface as the system. This is especially important for impact printers whose vibrations could damage the hard disk. ATTENTION In order to fully separate the system from current, the power cord must be removed from the wall outlet MAXDATA PLATINUM 510 Server 7 Connecting the system Rear Connectors Figure 1.

Serial Ports The mainboard provides one DB9 connector on the back panel for serial port A. Serial port A is compatible with 16550A and 16450 modes. The port can be set to one of four different COM ports and each can be enabled separately. When enabled, each port can be programmed to generate edgeor level-sensitive interrupts. When disabled, serial port interrupts are available to add-in cards. An additional serial header is available on the board for an optional serial port B. Parallel Port The mainboard provides a 25-pin parallel port back panel connector. The super I/O provides an IEEE 1284­compliant 25-pin bidirectional parallel port. BIOS programming of the super I/O registers enables the parallel port and determines the port address and interrupt. When disabled, the interrupt is available to add-in cards. Floppy Disk Connector The floppy disk connector on the server board provides the interface to the floppy disk drive from the floppy disk controller. Keyboard and Mouse Connectors The separate keyboard and mouse connectors, found on the back panel of the server board, are PS/2 compatible and are interchangeable. Setup does not include an option to disable the keyboard or mouse. Instead, they are automatically detected and tested at system startup. The system can be booted with either or both disconnected. USB The mainboard supports up to four high-speed USB 2.0 ports through the ICH4. Three ports are routed to the rear panel and one is routed to an internal 9-pin connector on the baseboard that can be cabled to an external connector located on the front or rear of a chassis. All four ports function identically and with the same bandwidth. MAXDATA PLATINUM 510 Server 17 Storage Serial ATA Controller The mainboard provides embedded dual Serial ATA channels using the Silicon Image 3112A PCI-toSerial ATA Controller. The 3112A SATA controller is a PCI-to-SATA controller of individual drives or a RAID configuration. The controller supports the following: · · · · · · · · Two SATA hard disk drives 150 MB/s data transfer RAID 0 (striping): adjustable stripe size. RAID 0 is used for high-performance applications RAID 1 (mirroring): RAID 1 is used for data protection Online mirror rebuilding Multiple sizes of hard disk drives Automatic selection of the highest available transfer speed for all ATA and ATAPI drives Booting from an individual drive or RAID set of drives The SATA drives can be enabled or disabled as a RAID set by running a utility to turn RAID mode on or off and loading the appropriate operating system driver. To use the RAID option, two SATA hard disk drives are required. When RAID is disabled, the drives are treated as individual ATA drives. NOTE Some operating systems will not support RAID mode. IDE Controller The ICH4 acts as a PCI-based Ultra DMA 100 IDE controller that supports programmed I/O transfers and bus master IDE transfers. The ICH4 supports two IDE channels, supporting two drives each for a maximum of four devices. Network Interface Controllers (NICs) The mainboard includes two integrated on-board Ethernet connections: · · One 10/100/1000Base-TX network controller based on the Intel® 82540EM Gigabit Ethernet Controller. One 10Base-T/100Base-TX network controller based on the Intel® 82550PM Fast Ethernet Multifunction PCI/CardBus Controller. As a PCI bus master, the 82550PM can burst data at up to 132 MB/s. Status LEDs are included on the external NIC connectors. You can disable the embedded NICs in BIOS Setup Utility. When disabled they are not visible to the operating system. NIC Connector and Status LEDs The mainboard supports two RJ-45 connectors, 10/100 Mbps Fast Ethernet controller (NIC1) and one for the one for the gigabit ethernet controller (NIC2). As you look at the rear I/O panel of the board, the NICs are in the following locations: · · NIC1 (10/100 megabit): The left connector, looking at the system from the back. NIC2 (1 gigabit): The right connector, looking at the system from the back. The NICs each drive two LEDs on their RJ-45 connectors: one to indicate a link on the Local Area Network (LAN) and the other to indicate the speed of operation. Table 3 describes the functionality of the LEDs. 18 Features Table 3. NIC1 and NIC2 Rear Panel LED Description NIC NIC1 (10/100 Mbit) LED Color Left LED LED State Off Solid Green On Blinking Green Off Left LED Solid Amber Blinking Amber Off Right LED Solid Amber Solid Green Description 10 Mbps 100 Mbps On Transmit/receive activity No network connection Network connection in place Transmit/receive activity 10 Mbps connection 100 Mbps connection 1000 Mbps connection Right LED NIC2 (Gigabit) Power Management The Advance 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. In this state, the power supply is still on and the processors still dissipate some power, so the power supply fan and processor fans are still running. NOTE ACPI requires an operating system that supports this feature. The mainboard supports sleep states S0, S1, S4, and S5. When the server board is operating in ACPI mode, the operating system retains control of the system and the operating system policy determines the entry methods and wake-up sources for each sleep state. Sleep entry and wake-up event capabilities are provided by the hardware but are enabled by the operating system. Following is a summary of the supported sleep states: · · · 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 Save to Disk. The memory and machine state are saved to disk. Pressing the power button or another wake-up event restores the system state from the disk and resumes normal operation. This state assumes that no hardware changes were made to the system while it was off. S5: Soft off. Only the RTC section of the chipset is running in this state. · CAUTION The system is off only when the AC power is disconnected. MAXDATA PLATINUM 510 Server 19 Front Panel Buttons The power button on the front panel behaves differently depending on whether the operating system supports ACPI. If the operating system supports ACPI, the power button can be configured as a sleep button. The OS causes the system to transition to the appropriate system state depending on the user settings. The front panel provides the following power control buttons at the front of the system: · · Power Button (Legacy): In legacy mode, the power button powers the system on or off. When the power is off, the power button turns the system on. Power Button (ACPI): If an ACPI operating system is loaded, the operating system retains control of the system and determines which sleep state (if any) the system transitions to. If the system is asleep, the power button wakes the system up. Reset Button: The reset button generates a hard reset to the system. When this button is pressed, the system acts as if it was powered off and then back on. · AC Link Mode The AC link mode allows the system to monitor its AC input power so that if AC input power is lost and then restored, the system returns to one of the following preselected settings: · · · Power On Last State (Factory Default Setting) Stay Off The AC link mode settings can be changed by running the BIOS Setup Utility. Wake on LAN Wake on LAN allows system power to be activated through the network when this option is enabled in Setup. If the system is in the S1 or S4 state, it can be turned on remotely by sending a specific packet to the system. Wake on RTC Wake on RTC alarm allows system power to be activated through a real-time clock alarm when this system is enabled in Setup. If the system is in the S1 or S4 state, it can be turned on by an RTC trigger event. Security The mainboard BIOS provides the ability to secure itself. Table 4 summarizes the password options available in the mainboard BIOS. Table 4. Security Operation Summary Mode User Password on boot (AT style) Entry Method/ Event Power On/ Reset Entry Criteria User Password set and password on boot enabled Behavior System halts for User Password before booting. The system is not in secure mode. Except for the password, no mouse or keyboard input is accepted. Exit Criteria User Password followed by [Enter] After Exit Power and Reset switches are enabled. Keyboard and mouse inputs are accepted. The system boots normally. Boot sequence is determined by setup options. 20 Features
