1: Detailed Chassis Description Table 1-2 (continued) Chassis Feature Summary Feature Description E. Electronics Bay (E-Bay) The E-Bay contains the baseboard.
Peripherals Table 1-2 (continued) Chassis Feature Summary Feature Description E5. Baseboard Form-factor, 16 (13 inches, ATX-style backpanel I/O) The baseboard is mounted horizontally in a subassembly called the E-Bay. The E-Bay is mounted towards the rear of the chassis. The baseboard contains connectors for installing up to four Pentium III Xeon processors in single-edge contact (SEC) cartridges. E6.
1: Detailed Chassis Description Hard Drive Bay The chassis contains one hard drive bay. The hard drive bay accommodates up to five 3.5-inch by 1.0-inch hot-swap Ultra 160 SCSI SCA hard drives You can access the hard drives by opening the front bezel door. As part of the hot-swap implementation, each hard drive requires a hard drive carrier. When you remove a hard drive from the system, you remove both the carrier and the hard drive. The drive is attached to the carrier by four screws.
Power Subsystem An LED above each hard drive displays the status of that hard drive. Table 1-3 shows the hard drive LED status. Table 1-3 Hard Drive LED State Status LED State Status Solid green The hard drive is present and powered on. Flashing green The hard drive is active. Solid yellow There is an asserted fault status on the hard drive. Flashing yellow A rebuild of the hard drive is in progress. Off The hard drive is not powered on.
1: Detailed Chassis Description A Figure 1-6 Power Subsystem Warning: The total power requirement for the SGI 1450 server exceeds the 240 VA energy hazard limit that defines an operator-accessible area. Only qualified service technicians should access the processor, memory, power subsystem, and non-hot-plug areas of the baseboard. The power subsystem consists of a power subsystem bay, with up to three power supply modules. The power supply modules are noted by “A” in Figure 1-6.
Power Subsystem The SGI 1450 server uses a redundant (2+1) power subsystem. To form a (2+1) redundant power subsystem, the subsystem parallels the DC output of one power supply module with one or two other modules. If one module ceases to function normally, the remaining modules provide power to the server system and the system continues to function properly. Two power supply modules are required to provide power to a fully configured SGI 1450 server. The third module provides redundancy.
1: Detailed Chassis Description DC power is sourced through 20-pin and 24-pin power cables to the baseboard. Remote sensing signals are provided through one 14-pin auxiliary power cable to the baseboard. The AC power status of each power supply module is indicated by an LED. The LED is located on the power supply module. Table 1-4 shows the AC power LED status. Table 1-4 AC Power LED State Status LED State Status Solid green AC power is applied to the power subsystem and standby voltage is available.
System Cooling A Figure 1-7 Fan Board Assembly The cooling system supports either a non-redundant configuration or a redundant configuration. A non-redundant configuration includes just three fans. If any one of these three fans ceases to function normally, environmental conditions within the chassis may exceed the environmental regulations in this guide and the chassis may not function normally. Three fans support any system configuration but without fan redundancy.
1: Detailed Chassis Description An LED above each cooling fan displays the status of that fan. The LEDs for two fans are noted by “A” in Figure 1-8. The LED on the left indicates the status of the fan pointed to by the left arrow. The LED on the right indicates the status of the fan pointed to by the right arrow. A Figure 1-8 Fan LEDs Table 1-5 shows the fan LED state status.
E-Bay patterns are disrupted within the system. To maintain correct airflow patterns within the chassis and to ensure that all components remain within specification under all system environmental conditions, fan hot-swap operations should not exceed two minutes in duration. E-Bay The E-Bay contains the baseboard with the following components: • Up to four Intel Pentium III Xeon processors. The baseboard has four SC330.1 connectors; each supports a processor.

A: Technical Reference provides a mechanism for chassis power control. As an option, you can configure a server with an ICMB adapter board to provide two SEMCONN 6-pin connectors for daisy-chained cabling. Table A-29 shows the cable pinout assignments for the ICMB connector.
Baseboard Connectors The baseboard only supports monitoring a total of eight tachometer fan inputs. The front panel connector provides connections to all eight tachometer fan inputs. The tachometer signals from these four processor fan connectors are connected to the same tachometer fan signals FAN_TACH(4), FAN_TACH(5), FAN_TACH(6), and FAN_TACH(7) provided on the front panel connector J9E3. Therefore, make sure that only one connection is used at any given time.

We recommend that you do all procedures in this chapter only at an ESD-protected workstation.
A: Technical Reference There are two methods to restore the default values. Method 1 1. Hold down the system's reset button down for five seconds. 2. While continuing to hold down the system's reset button, press the power button. 3. Release both the reset and power buttons at the same time. Method 2 1. Observe the safety and ESD precautions at the beginning of this section. 2. Turn off all connected peripherals, turn off system power, and disconnect all AC power cords. 3.
Changing Jumper Settings 13. If the baseboard is installed in a system, reinstall the access covers, connect the power cords, and turn on the system for the change to take effect. 14. Run BIOS Setup or the SSU to verify the correct settings. See Chapter 3 in the SGI 1450 Server User’s Guide. Password Clear Jumper The jumper at pins 5, 6, and 7 controls whether a stored password is retained or cleared during a system reset. Follow these steps to clear the current password and then enter a new one: 1.
A: Technical Reference Recovery Boot Jumper The jumper at pins 9, 10, and 11 controls whether the system attempts to boot using the BIOS programmed in flash memory. Follow these steps to disable recovery booting: 1. Observe the safety and ESD precautions at the beginning of this section. 2. Turn off all connected peripherals, turn off system power, and disconnect all AC power cords. 3. If the baseboard is installed in a system, remove access covers so that you have access to the baseboard. 4.
Interrupts 9. Wait for POST to complete and for the message Press F1 to resume, Press F2 to Setup to be displayed. 10. Turn off the system, and disconnect all AC power cords from the system. 11. Move the jumper from pins 6 and 7 back to pins 5 and 6. 12. If the baseboard is installed in a system, reinstall the access covers, connect the power cords, and turn on the system for the change to take effect. 13. After running the special recovery mode, run the SSU to specify a new password.
