A fan on the processor heat sink is not necessary in this chassis. In order to maintain the necessary airflow within the system, the air baffle, CPU/Memory air duct, and the top cover need to be properly installed.

Note: The Server Chassis SC1400UP does not support redundant cooling. Should a fan fail, the system should be brought down as soon as possible to replace the failed fan.

2.1 System Fans

The Intel® Server Chassis SC1400UP system fans consist of four 40x40x56mm dual rotor and one 40x40x28mm single rotor multi-speed fans, which provide the primary airflow for the system. The four dual rotor fans provide the primary cooling for the CPU, GMCH, and memory components on the Intel Server Board SE7221BK1-E. The single rotor fan provides the primary cooling for PCI add-in cards, the ICH6R and PXH chipset components.

Removal and insertion of individual fans is a tool-less operation, and provides for ease of installation and serviceability of the server chassis cooling subsystem. The individual fans are not hot swappable. The server must be turned off and power removed from the system before any of the fans can safely be replaced.

Each dual rotor fan has an 8-pin wire harness which connects to the system fan headers 5,6,7 and 8 on the Intel Server Board SE7221BK1-E. These are shown, from left to right, in the following figure. Each fan harness provides power and tachometer lines allowing the fans to be monitored independently by server management software. The fan distribution board has a 20pin connector which provides the power and communication signal path from the baseboard.

Figure 10. Intel® Server Chassis SC1400UP System Fans 4, 5, 6, 7, 8

Revision 1.0 - 21 -

Intel® Server Chassis SC1400UP / Intel® Server Platform SR1425BK1-E

The following table provides the pin-outs for each dual rotor fan header.

Table 2. Individual Fan Assy Pinout (J6J1, J6J2, J6J3, J6J4)

Pin Signal Name Description

1 FAN_SPEED_CNTL2 Control the fan speed 2 FAN_FAIL FAN_TACH signal 3 GND Power Supply Ground 4 Reserved Reserved 5 GND Power Supply Ground 6 GND Power Supply Ground 7 FAN_FAIL FAN_TACH signal 8 Fan speed control Variable Speed Fan Power

The single rotor fan is a standard 3 pin SSI fan header that connects directly to the baseboard system fan header #4 (JP5J2).

Each fan within the module is capable of supporting multiple speeds. If the internal ambient temperature of the system exceeds the value programmed into the thermal sensor data record (SDR), the Baseboard Management Controller (BMC) firmware will increase the rotational speed for all the fans within fan module.

Note: There is no fan redundancy. Should a fan fail, the system should be shut down as soon as possible to have the fan replaced. The system fans are not hot-swapable.

2.2 Power Supply Fans

The power supply supports two non-redundant 40mm fans. They are responsible for the cooling of the power supply and drive bay 1 (the far left hard drive as viewed from the front of the chassis).

2.3 CPU/Memory Air Duct and Side Air Baffle

The chassis requires the use of a CPU/Memory air duct and power supply / electronics bay isolation air baffle to direct airflow and sustain appropriate air pressure.

An air baffle is used to isolate airflow of the two power supply fans from that of the system fan module. The baffle is mounted into three stand-offs with one end fitting under the back edge of the hard drive bay

The CPU/Memory air duct must be properly installed to direct airflow through the processor heatsink(s) to the low profile PCI and memory area of the system. The CPU air duct is

Revision 1.0 - 22 -

Figure 12. Air Baffle

Intel® Server Chassis SC1400UP / Intel® Server Platform SR1425BK1-E

designed to support either a single or dual processor configuration. For single processor configurations the pre-installed air damn must be left in place in order to maintain necessary air pressure and air flow through the processor heat sink. For dual processor configurations, the air damn must be snapped off of the CPU air duct. The CPU air duct cannot be installed if the air damn is in place and two processors are installed.

Figure 13. CPU/Memory Air Duct

Note: If the CPU/Memory air duct is removed, the system will not meet the thermal cooling

requirements of the processor, which will most likely result in degraded performance as a result of throttling or thermal shutdown of the system.

Note: Once the air damn is removed from the CPU air duct, it cannot be reinstalled.

2.4 Hard Drive Bays

Hard drive bays must be populated in order to maintain system thermals. Hard drive trays, both hot-swap and cabled drive, must ether have a hard drive or drive blank installed in them.

Revision 1.0 - 23 -

3.2 Hard Disk Drive Bays

The server chassis SC1400UP can be configured to support either hot swap SCSI or SATA hard disk drives or fixed SATA drive configurations. For hot swap drive configurations, 3.5” x 1” hard disk drives are mounted to hot swap drive trays for easy insertion to or extraction from the drive bay. For cabled drive configurations, the SATA drives are mounted to a drive tray which is only removable from inside the chassis.

Note: All hard drive bays must be populated to maintain system thermals. Drive trays should either have a hard drive or drive blank inserted.

Revision 1.0 - 27 -

Intel® Server Chassis SC1400UP / Intel® Server Platform SR1425BK1-E

3.2.1 Hot Swap Hard Disk Drive Trays

In a hot swap configuration, each hard drive must be mounted to a hot swap drive tray, making insertion and extraction of the drive from the chassis very simple. Each drive tray has its own dual purpose latching mechanism which is used to both insert/extract drives from the chassis and lock the tray in place. Each drive tray supports a light pipe providing a drive status indicator, located on the backplane, to be viewable from the front of the chassis.

Note: Depending on the controller used, SATA hard disk drives may not report errors using the drive’s status indicator.

3.2.2 Fixed Drive Trays

In a fixed drive configuration, each SATA/SCSI hard drive must be mounted to a non-hot swap drive tray. The tray is designed to slide into the drive bay and lock into place. To remove the drive, the chassis must be opened to disengage the drive tray latch from the bay.

3.2.3 Drive Blanks

Drive blanks must be used when no drive is used in a hard drive bay. Drive blanks simulate the spatial volume of a hard disk which is required to maintain proper air pressure limits necessary to cool the system.

Notes:

1. Blink rate is ~1 Hz with at 50% duty cycle.

2. The amber status takes precedence over the green status. When the amber LED is on or blinking, the green LED is off.

3. Also off when the system is powered off (S4/S5) or in a sleep state (S1).

4. The power LED sleep indication is maintained on standby by the chipset. If the system is powered down without going through BIOS, the LED state in effect at the time of power off will be restored when the system is powered on until the BIOS clears it. If the system is not powered down normally, it is possible that the Power LED will be blinking at the same time that the system status LED is off due to a failure or configuration change that prevents the BIOS from running.

The current limiting resistors for the power LED, the system fault LED, and the NIC LEDs are located on the server board SE7221BK1-E.

configured with an Intel Management Module. Refer to the baseboard technical product specification for details.

Revision 1.0 - 44 -

Intel® Server Chassis SC1400UP / Intel® Server Platform SR1425BK1-E

4.2.2.1 Critical Conditions

A critical condition is any critical or non-recoverable threshold crossing associated with the following events:

• Temperature, voltage, or fan critical threshold crossing.

• Power subsystem failure. The BMC asserts this failure whenever it detects a power

control fault (e.g., the BMC detects that the system power is remaining ON even though the BMC has deserted the signal to turn off power to the system.

• A hot-swap backplane would use the Set Fault Indication command to indicate when one

or more of the drive fault status LEDs are asserted on the hot-swap backplane.

• The system is unable to power up due to incorrectly installed processor(s), or processor

incompatibility.

• Satellite controller sends a critical or non-recoverable state, via the Set Fault Indication

command to the BMC.

• Critical event logging errors, including: System Memory Uncorrectable ECC error, and

fatal / uncorrectable bus errors such as PCI SERR and PERR.

4.2.2.2 Non-Critical Conditions

A non-critical condition is threshold crossing associated with the following events:

• Temperature, voltage, or fan non-critical threshold crossing

• Chassis intrusion

• Satellite controller sends a non-critical state, via the Set Fault Indication command, to

the BMC.

• Set Fault Indication command from system BIOS. The BIOS may use the Set Fault

Indication command to indicate additional ‘non-critical’ status such as a system memory or CPU configuration changes.

4.2.2.3 Degraded Conditions

A degraded condition is associated with the following events:

• Non-redundant power supply operation. This applies only when the BMC is configured

for a redundant power subsystem.

• One or more processors are disabled by Fault Reliant Booting (FRB) or BIOS.

• BIOS has disabled or mapped out some of the system memory.

4.2.3 Drive Activity LED

The drive activity LED on the front panel indicates drive activity from the onboard hard disk controllers. The server board SE7221BK1-E also provides a header giving access to this LED for add-in controllers.

4.2.4 System Identification LED

The blue system identification LED is used to help identify a system for servicing. This is especially useful when the system is installed when in a high density rack or cabinet that is populated with several similar systems. The system ID LED will blink when the System ID button on the control panel is pressed or it can be illuminated remotely through server management software.

If a monitor is connected to the front panel video connector, the rear video port on the server board will be disabled and the front panel video will be enabled. The video source is the same for both connectors and is switched between the two, with the control panel having priority over the rear video. This provides for easy front accessibility to the server.

4.4 Internal Control Panel Assembly Headers

The Control Panel interface board has two internal headers:

A 50-pin header provides control and status information to/from the server board. Using a 50-pin flat cable, the header can either be connected to a matching connector on a hot swap backplane or, in cabled drive configurations, can be connected to a matching connector on the baseboard.

A 10-pin header is used to provide USB support to the control panel. The round 10-pin cable is routed from the control panel assembly to a matching connector on the baseboard.

The following tables provide the pin-outs for both types of connectors.

6.21 Remote Sense

The power supply has remote sense return (ReturnS) to regulate out ground drops for all output voltages; +3.3V, +5V, +12V, -12V, and 5VSB. The power supply uses remote sense (3.3VS) to regulate out drops in the system for the +3.3V output. The +5V, +12V, –12V and 5VSB outputs only use remote sense referenced to the ReturnS signal. The remote sense input impedance to the power supply must be greater than 200Ω on 3.3VS, 5VS. This is the value of the resistor connecting the remote sense to the output voltage internal to the power supply.
