1.4 Chassis Security

A variety of chassis security options are provided at the system level:

 A removable padlock loop at the rear of the system access cover can be used to prevent access to the microprocessors, memory, and add-in cards. A variety of lock sizes can be accommodated by the 0.270-inch diameter loop.

 A Kensington* cable lock mounting hole is provided on the rear chassis I/O panel.

 A chassis intrusion switch is provided, allowing server management software to detect unauthorized access to the system side cover.

 In hot-swap hard drives configuration, a door lock is provided on the front bezel assembly with the door to prevent access to the hot-swap hard drives and the interior of the chassis.

Note: See the Technical Product Specification appropriate to the server board for a description of BIOS and management security features for each specific supported platform.

Technical product specifications can be found at http://www.intel.com/support .

1.5 I/O Panel

All input/output (I/O) connectors are accessible from the rear of the chassis. The SSI E-bay

3.61-compliant chassis provides an ATX 2.2-compatible cutout for I/O shield installation.

Boxed Intel ® server boards provide the required I/O shield for installation in the cutout. The

I/O cutout dimensions are shown in the following figure for reference.

A. Security Lock

Figure 5. Front Closed Chassis View for Hot-swap Hard Drives Configuration

Both pedestal front bezels are constructed of molded plastic and attach to the front of the chassis with three clips on the right side and two snaps on the left. The snaps at the left attach behind the access cover, thereby preventing accidental removal of the bezel. The bezel can only be removed by first removing the server access cover. This provides additional security to the hard drive and peripheral bay area.

For the front bezel assembly for fixed hard drives configuration, removing the bezel, there is an EMI shield covering the fixed hard drives bay area.

5


For the front bezel assembly for hot-swap hard drives configuration, the bezel includes a key-locking door that covers the drive cage area and allows access to hot-swap drives when a hot-swap drive cage is installed.

Note: The chassis P4304XXMUXX is configured for fixed hard drive support by default, and supports hot-swap drive bay(s) as upgrade options.

2.1.3.2 AC Inlet Connector

The AC input connector is an IEC 320 C-14 power inlet.

This inlet is rated for 10A/250VAC.

2.1.3.3 AC Input Voltage Specification

The power supply operates within all specified limits over the following input voltage range.

Harmonic distortion of up to 10% of the rated line voltage does not cause the power supply to go out of specified limits. Application of an input voltage below 85VAC does not cause damage to the power supply, including a blown fuse.

Notes:

1. Maximum input current at low input voltage range shall be measured at 90VAC, at max load.

2. Maximum input current at high input voltage range shall be measured at 180VAC, at max load.

3. This requirement is not to be used for determining agency input current markings.

2.1.3.4 AC Line Dropout/Holdup

An AC line dropout is defined to be when the AC input drops to 0VAC at any phase of the AC line for any length of time. During an AC dropout the power supply meets dynamic voltage regulation requirements. An AC line dropout of any duration does not cause tripping of control signals or protection circuits. If the AC dropout lasts longer than the holdup time the power supply recovers and meets all turn on requirements. The power supply meets the AC dropout requirement over rated AC voltages and frequencies. A dropout of the AC line for any duration does not cause damage to the power supply.

Table 12. AC Line Holdup Time

Loading Holdup Time

75% 12msec

2.1.3.5 AC Line Fuse

The power supply has one line fused in the single line fuse on the line (Hot) wire of the AC input. The line fusing is acceptable for all safety agency requirements. The input fuse is a slow blow type. AC inrush current does not cause the AC line fuse to blow under any conditions. All protection circuits in the power supply do not cause the AC fuse to blow unless a component in the power supply has failed. This includes DC output load short conditions

2.1.3.6 AC Line Leakage Current

The maximum leakage current to ground for each power supply is 3.5mA when tested at

240VAC.

2.1.3.7 AC Line Transient Specification

AC line transient conditions are defined as “sag” and “surge” conditions. “Sag” conditions are also commonly referred to as “brownout”, these conditions is defined as the AC line voltage dropping below nominal voltage conditions. “Surge” is defined to refer to conditions when the

AC line voltage rises above nominal voltage.

The power supply meets the requirements under the following AC line sag and surge conditions.

2.1.5.7 Grounding

The output ground of the pins of the power supply provides the output power return path.

The output connector ground pins are connected to the safety ground (power supply enclosure). This grounding is well designed to ensure passing the max allowed Common Mode

Noise levels.

The power supply is provided with a reliable protective earth ground. All secondary circuits are connected to protective earth ground. Resistance of the ground returns to chassis does not exceed 1.0 m. This path may be used to carry DC current.

2.1.5.8 Residual Voltage Immunity in Standby Mode

The power supply is immune to any residual voltage placed on its outputs (Typically a leakage voltage through the system from standby output) up to 500mV. There is neither additional heat generated, nor stressing of any internal components with this voltage applied to any individual or all outputs simultaneously. It also does not trip the protection circuits during turn on.

The residual voltage at the power supply outputs for no load condition does not exceed

100mV when AC voltage is applied and the PSON# signal is de-asserted.

2.1.5.9 Common Mode Noise

The Common Mode noise on any output does not exceed 350mV pk-pk over the frequency band of 10Hz to 20MHz.

The measurement is made across a 100Ω resistor between each of DC outputs, including ground at the DC power connector and chassis ground (power subsystem enclosure).

The test setup shall use a FET probe such as Tektronix model P6046 or equivalent.

2.1.5.10 Ripple/Noise

The maximum allowed ripple/noise output of the power supply is defined in below table 20.

This is measured over a bandwidth of 10Hz to 20MHz at the power supply output connectors.

A 10F tantalum capacitor in parallel with a 0.1F ceramic capacitor is placed at the point of measurement.

2.1.5.11 Timing Requirements

These are the timing requirements for the power supply operation. The output voltages rise from 10% to within regulation limits (T vout_rise

) within 2 to 50ms, except for 5VSB - it is allowed to rise from 1 to 25ms. The +3.3V, +5V and +12V1, +12V2, +12V3 output voltages start to rise approximately at the same time. All outputs rise monotonically. Each output voltage reach regulation within 50ms (T vout_on

) of each other during turn on the power supply. Each output voltage fall out of regulation within 400ms (T vout_off

) of each other during turn off. Table 22 shows the timing requirements for the power supply being turned on and off by the AC input, with PSON held low and the PSON signal, with the AC input applied. All timing requirements are met for the cross loading condition in Table 17.

2.2.2.3 AC Input Voltage Specification

The power supply operates within all specified limits over the following input voltage range.

Harmonic distortion of up to 10% of the rated line voltage does not cause the power supply to go out of specified limits. Application of an input voltage below 85VAC does not cause damage to the power supply, including a blown fuse.

Notes:





An AC line dropout is defined to be when the AC input drops to 0VAC at any phase of the AC line for any length of time. During an AC dropout the power supply meets dynamic voltage regulation requirements. An AC line dropout of any duration does not cause tripping of control signals or protection circuits. If the AC dropout lasts longer than the holdup time the power supply recovers and meets all turn on requirements. The power supply meets the AC dropout requirement over rated AC voltages and frequencies. A dropout of the AC line for any duration does not cause damage to the power supply.

The 12VSB output voltage stays in regulation under its full load (static or dynamic) during an

AC dropout of 70ms min (=12VSB holdup time) whether the power supply is in ON or OFF state (PSON asserted or de-asserted).


The power supply has one line fused in the single line fuse on the line (Hot) wire of the AC input. The line fusing is acceptable for all safety agency requirements. The input is a slow blow type. AC inrush current does not cause the AC line fuse to blow under any conditions. All protection circuits in the power supply does not cause the AC fuse to blow unless a component in the power supply has failed. This includes DC output load short conditions.


AC line transient conditions are defined as “sag” and “surge” conditions. “Sag” conditions are also commonly referred to as “brownout”, these conditions is defined as the AC line voltage dropping below nominal voltage conditions. “Surge” is defined to refer to conditions when the

AC line voltage rises above nominal voltage.

The output connector ground pins are connected to the safety ground (power supply enclosure). This grounding is well designed to ensure passing the max allowed Common Mode

Noise levels.

The power supply is provided with a reliable protective earth ground. All secondary circuits is connected to protective earth ground. Resistance of the ground returns to chassis does not exceed 1.0 m. This path may be used to carry DC current.


The power supply is immune to any residual voltage placed on its outputs (Typically a leakage voltage through the system from standby output) up to 500mV. There is neither additional

32

Intel® Server Chassis P4304XXMFEN2 / P4304XXMUXX TPS Chassis Power Subsystem heat generated, nor stressing of any internal components with this voltage applied to any individual or all outputs simultaneously. It also does not trip the protection circuits during turn on.

The residual voltage at the power supply outputs for no load condition does not exceed

100mV when AC voltage is applied and the PSON# signal is de-asserted.


The Common Mode noise on any output does not exceed 350mV pk-pk over the frequency band of 10Hz to 20MHz.

The measurement is made across a 100Ω resistor between each of DC outputs, including ground at the DC power connector and chassis ground (power subsystem enclosure).


2.2.4.9 Hot Swap Requirements

Hot swapping a power supply is the process of inserting and extracting a power supply from an operating power system. During this process the output voltages remains within the limits with the capacitive load specified. The hot swap test is conducted when the system is operating under static, dynamic, and zero loading conditions. The power supply uses a latching mechanism to prevent insertion and extraction of the power supply when the AC power cord is inserted into the power supply.

2.2.4.10 Forced Load Sharing

The +12V output will have active load sharing. The output will share within 10% at full load.

The failure of a power supply does not affect the load sharing or output voltages of the other supplies still operating. The supplies are able to load share in parallel and operate in a hotswap/redundant 1+1 configurations. The 12VSB output is not required to actively share current between power supplies (passive sharing). The 12VSB output of the power supplies are connected together in the system so that a failure or hot swap of a redundant power supply does not cause these outputs to go out of regulation in the system.


The maximum allowed ripple/noise output of the power supply is defined in below table. This is measured over a bandwidth of 10Hz to 20MHz at the power supply output connectors. A

10F tantalum capacitor in parallel with a 0.1F ceramic capacitor is placed at the point of measurement.

These are the timing requirements for the power supply operation. The output voltages must rise from 10% to within regulation limits (T vout_rise

The power supply over voltage protection is locally sensed. The power supply shuts down and latches off after an over voltage condition occurs. This latch is cleared by toggling the PSON # signal or by an AC power interruption. The values are measured at the output of the power supply’s connectors. The voltage does not exceed the maximum levels when measured at the power connectors of the power supply connector during any single point of fail. The voltage doesn’t trip any lower than the minimum levels when measured at the power connector.

2.2.5.3 Over Temperature Protection (OTP)

The power supply will be protected against over temperature conditions caused by loss of fan cooling or excessive ambient temperature. In an OTP condition the PSU will shut down. When the power supply temperature drops to within specified limits, the power supply shall restore power automatically, while the 12VSB remains always on. The OTP circuit must have built in margin such that the power supply will not oscillate on and off due to temperature recovering condition. The OTP trip level shall have a minimum of 4C of ambient temperature margin.



Signals that can be defined as low true use the following convention: Signal# = low true.


The PSON # signal is required to remotely turn on/off the power supply. PSON # is an active low signal that turns on the +12V power rail. When this signal is not pulled low by the system, or left open, the outputs (except the +12VSB) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply. Refer to Figure 21 for the timing diagram.

2.3.3.8 Closed Loop Stability

The power supply shall be unconditionally stable under all line/load/transient load conditions including capacitive load ranges specified in Section 2.3.3.5. A minimum of: 45 degrees phase

margin and -10dB-gain margin is required. The power supply manufacturer shall provide proof of the unit’s closed-loop stability with local sensing through the submission of Bode

There shall be no additional heat generated, nor stressing of any internal components with this voltage applied to any individual or all outputs simultaneously. It also should not trip the protection circuits during turn on.

The residual voltage at the power supply outputs for no load condition shall not exceed

100mV when AC voltage is applied and the PSON# signal is de-asserted.


The Common Mode noise on any output shall not exceed 350mVp-p over the frequency band of 10Hz to 20MHz.



The measurement shall be made across a 100Ω resistor between each of DC outputs, including ground at the DC power connector and chassis ground (power subsystem enclosure).


2.3.3.11 Soft Starting

The Power Supply shall contain control circuit which provides monotonic soft start for its outputs without overstress of the AC line or any power supply components at any specified

AC line or load conditions.

2.3.3.12 Zero Load Stability Requirement

When the power subsystem operates in a no load condition, it does not need to meet the output regulation specification, but it must operate without any tripping of over-voltage or other fault circuitry. When the power subsystem is subsequently loaded, it must begin to regulate and source current without fault.

2.3.3.13 Hot Swap Requirement

Hot swapping a power supply is the process of inserting and extracting a power supply from an operating power system. During this process the output voltages shall remain within the limits with the capacitive load specified. The hot swap test must be conducted when the system is operating under static, dynamic, and zero loading conditions. The power supply shall use a latching mechanism to prevent insertion and extraction of the power supply when the AC power cord is inserted into the power supply.

2.3.3.14 Forced Load Sharing

The +12V output will have active load sharing. The output will share within 10% at full load.

The failure of a power supply should not affect the load sharing or output voltages of the

49

Chassis Power Subsystem Intel® Server Chassis P4304XXMFEN2 / P4304XXMUXX TPS other supplies still operating. The supplies must be able to load share in parallel and operate in a hot-swap/redundant 1+1 configurations. The 12VSBoutput is not required to actively share current between power supplies (passive sharing). The 12VSBoutput of the power supplies are connected together in the system so that a failure or hot swap of a redundant power supply does not cause these outputs to go out of regulation in the system.

2.3.3.15 Timing Requirement

These are the timing requirements for the power supply operation. The output voltages must rise from 10% to within regulation limits (T vout_rise

) within 5 to 70ms. For 12VSB, it is allowed to rise from 1.0 to 25ms. All outputs must rise monotonically. Table below shows the timing requirements for the power supply being turned on and off through the AC input, with PSON held low and the PSON signal, with the AC input applied.

2.3.4 Power Supply Cold Redundancy Support

Power supplies that support cold redundancy can be enabled to go into a low-power state

(that is, cold redundant state) in order to provide increased power usage efficiency when system loads are such that both power supplies are not needed. When the power subsystem is in Cold Redundant mode, only the needed power supply to support the best power delivery efficiency is ON. Any additional power supplies; including the redundant power supply, is in

Cold Standby state.

Each power supply has an additional signal that is dedicated to supporting Cold Redundancy;

CR_BUS. This signal is a common bus between all power supplies in the system. CR_BUS is asserted when there is a fault in any power supply OR the power supplies output voltage falls below the Vfault threshold. Asserting the CR_BUS signal causes all power supplies in Cold

Standby state to power ON.

Enabling power supplies to maintain best efficiency is achieved by looking at the Load Share bus voltage and comparing it to a programmed voltage level through a PMBus command.

Whenever there is no active power supply on the Cold Redundancy bus driving a HIGH level on the bus all power supplies are ON no matter their defined Cold Redundant roll (active or

Cold Standby). This guarantees that incorrect programming of the Cold Redundancy states of the power supply will never cause the power subsystem to shut down or become over loaded.

The default state of the power subsystem is all power supplies ON. There needs to be at least

51

Chassis Power Subsystem Intel® Server Chassis P4304XXMFEN2 / P4304XXMUXX TPS one power supply in Cold Redundant Active state or Standard Redundant state to allow the

Cold Standby state power supplies to go into Cold Standby state.

Caution: Installing two Power Supply Units with different wattage ratings on a system is not supported. This will not provide Power Supply Redundancy and causes the system to log multiple errors.

2.3.4.1 1600W CRPS Cold Redundancy

If the output power is less than 640W (40%). the Cold redundant function will be enable. Thus you will see one PSU working normal. The second PSU will be CR mode. The Power Supply

LED is green blinking.

Signals that can be defined as low true use the following convention: Signal# = low true.


The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the +12V power rail. When this signal is not pulled low by the system, or left open, the outputs (except the +12VSB) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply. Refer to Figure 25 for the timing diagram.

2.3.5.2 PWOK (power good) Output Signal

PWOK is a power OK signal and will be pulled HIGH by the power supply to indicate that all the outputs are within the regulation limits of the power supply. When any output voltage falls below regulation limits or when AC power has been removed for a time sufficiently long so that power supply operation is no longer guaranteed, PWOK will be de-asserted to a LOW state. See the table below for a representation of the timing characteristics of PWOK. The start of the PWOK delay time shall inhibited as long as any power supply output is in current limit.

The power supply shall have current limit to prevent the outputs from exceeding the values shown in table below. If the current limits are exceeded the power supply shall shutdown and latch off. The latch will be cleared by toggling the PSON# signal or by an AC power interruption.

2.4.2.12 DC/DC Converters Closed Loop stability

Each DC/DC converter is unconditionally stable under all line/load/transient load conditions including capacitive load ranges specified in Section 2.4.2.11. A minimum of: 45 degrees

phase margin and -10dB-gain margin is required. The PDB provides proof of the unit’s closed-loop stability with local sensing through the submission of Bode plots. Closed-loop stability must be ensured at the maximum and minimum loads as applicable.


The Common Mode noise on any output does not exceed 350mV pk-pk over the frequency band of 10Hz to 20MHz.

 The measurement shall be made across a 100Ω resistor between each of DC outputs, including ground, at the DC power connector and chassis ground (power subsystem enclosure).

 The test setup shall use a FET probe such as Tektronix model P6046 or equivalent.


The maximum allowed ripple/noise output of each DC/DC Converter is defined in below Table

132. This is measured over a bandwidth of 0Hz to 20MHz at the PDB output connectors. A

10F tantalum capacitor in parallel with a 0.1F ceramic capacitor are placed at the point of measurement.

Each DC/DC converter is immune to any residual voltage placed on its respective output

(typically a leakage voltage through the system from standby output) up to 500mV. This residual voltage does not have any adverse effect on each DC/DC converter, such as: no additional power dissipation or over-stressing/over-heating any internal components or adversely affecting the turn-on performance (no protection circuits tripping during turn on).

65


While in Stand-by mode, at no load condition, the residual voltage on each DC/DC converter output does not exceed 100mV.


The PDB shall shut down all the DC/DC converters on the PDB and the power supply (from

PSON) if there is a fault condition on the PDB (OVP or OCP). If the PDB DC/DC converter latches off due to a protection circuit tripping, an AC cycle OFF for 15sec min or a PSON# cycle HIGH for 1sec shall be able to reset the power supply and the PDB.

2.4.3.1 Over-Current Protection (OCP) / 240VA Protection

Each DC/DC converter output on PDB has individual OCP protection circuits. The PS+PDB combo shall shutdown and latch off after an over current condition occurs. This latch shall be cleared by toggling the PSON # signal or by an AC power interruption. The values are measured at the PDB harness connectors. The DC/DC converters shall not be damaged from repeated power cycling in this condition. Also, the +12V output from the power supply is divided on the

PDB into 3 channels and +12V3 is limited to 240VA of power. There are current sensors and limit circuits to shut down the entire PS+PDB combo if the limit is exceeded. The limits are listed in below table. -12V and 5VSB is protected under over current or shorted conditions so that no damage can occur to the power supply. Auto-recovery feature is a requirement on

5VSB rail.

Each DC/DC converter output on PDB have individual OVP protection circuits built in and it shall be locally sensed. The PS+PDB combo shall shutdown and latch off after an over voltage condition occurs. This latch shall be cleared by toggling the PSON # signal or by an AC power interruption. Table 135 contains the over voltage limits. The values are measured at the PDB harness connectors. The voltage shall never exceed the maximum levels when measured at the power pins of the output harness connector during any single point of fail. The voltage shall never trip any lower than the minimum levels when measured at the power pins of the

Chassis Cooling Intel® Server Chassis P4304XXMFEN2 / P4304XXMUXX TPS

3. Chassis Cooling

The Intel ® Server Chassis P4304XXMFEN2 provides a base cooling solution which includes two

120 x 38mm fixed fans to provide sufficient system cooling. The Intel ® Server Chassis

P4304XXMUXX provides a redundant cooling solution which is designed for maximum up time by providing five 80 x 38 mm replaceable hot-swap fans. The fans can maintain proper system cooling, even with a single failed fan. Corresponding air ducts are needed in both configurations for supported boards.

3.1 Non-Redundant Cooling Solution on P4304XXMFEN2

Two 120 x 38 mm fans provide cooling for the processors, memory, hard drives and add-in cards. The two fans draw air through the rear of each hard drive bay to provide drive, processors, and memory cooling. All system fans provide a signal for RPM detection the server board can make available for server management functions.

In addition, the power supply fan provides cooling for the power supply.

Figure 29. Fixed Fans in Intel ® Server Chassis P4304XXMFEN2

3.2 Redundant Cooling Solution on P4304XXMUXX

Five hot-swap 80x38mm fans provide cooling for the processors, hard drives, and add-in cards. When any single fan fails, the remaining fans increase in speed and maintain cooling until the failed unit is replaced. All system fans provide a signal for RPM detection that the server board can make available for server management functions.

In addition, the power supply fan provides cooling for the power supply.

68

Intel® Server Chassis P4304XXMFEN2 / P4304XXMUXX TPS Chassis Cooling

Figure 30. Hot-swap Fans in Intel ® Server Chassis P4304XXMUXX

3.3 Fan Control

The fans provided in the Intel ® Server Chassis P4304XXMFEN2 / P4304XXMUXX contain a tachometer signal that can be monitored by the server management subsystem of the Intel

Server Boards for RPM (Revolutions per Minute) detection.

®

The server board monitors several temperature sensors and adjusts the PWM (Pulse Width

Modulated) signal to drive the fan at the appropriate speed.

The front panel of the chassis has a digital temperature sensor connected to the server board through the front panel’s bus. The server board firmware adjusts the fan speed based on the front panel intake temperature and processor temperatures.

Refer to the baseboard documentation for additional details on how fan control is implemented.

3.4 Fan Header Connector Descriptions

All system fan headers support pulse width modulated (PWM) fans for cooling the processors in the chassis. PWM fans have an improved RPM range (20% to 100% rated fan speed) when compared to voltage controlled fans.

Fixed chassis fans are in a 4-wire/4-pin style designed to plug into 4-pin or 6-pin SSI Fan headers. When plugged into a 6-pin header, only the first four signals are used (Pwr, Gnd,

Tach, and PWM).

Hot-swap chassis fans are in a 6-wire/6-pin style designed to plug into 6-pin headers. The extra signals provide for fan redundancy and failure indications (Pwr, Gnd, Tach, PWM,

Presence, and Failure).

4.3 Front Control Panel LED/Button Functionality

ID Button with integrated ID LED – Toggles the integrated ID LED and the Blue server board

ID LED on and off. The ID LED is used to identify the system for maintenance when installed in a rack of similar server systems. The ID LED can also be toggled on and off remotely using the

IPMI Chassis Identify command which will cause the LED to blink for 15 seconds.

NMI Button – When the NMI button is pressed, it puts the server in a halt state and issues a non-maskable interrupt (NMI). This can be useful when performing diagnostics for a given issue where a memory download is necessary to help determine the cause of the problem. To prevent an inadvertent system halt, the actual NMI button is located behind the Front Control

Panel faceplate where it is only accessible with the use of a small tipped tool like a pin or paper clip.

Network Activity LEDs (NIC LED) – The Front Control Panel includes an activity LED indicator for each on-board Network Interface Controller (NIC). When a network link is detected, the

LED will turn on solid. The LED will blink once network activity occurs at a rate that is consistent with the amount of network activity that is occurring.

System Reset Button – When pressed, this button will reboot and re-initialize the system.

System Status LED – The System Status LED is a bi-color (Green/Amber) indicator that shows the current health of the server system. The system provides two locations for this feature; one is located on the Front Control Panel, the other is located on the back edge of the server board, viewable from the back of the system. Both LEDs are tied together and will show the same state. The System Status LED states are driven by the on-board platform management subsystem.

System Power Button with power LED – Toggles the system power on and off. This button also functions as a sleep button if enabled by an ACPI compliant operating system. Pressing this button will send a signal to the Integrated BMC, which will either power on or power off the system. The integrated LED is a single color (Green) and is capable of supporting different indicator states as defined in the following table.

Hot-Swap Backplane (Optional) Intel® Server Chassis P4304XXMFEN2 / P4304XXMUXX TPS

5. Hot-Swap Backplane (Optional)

The Intel ® Server Chassis P4304XXMUXX supports hot-swap front bezel door. The fixed storage drive trays can be upgraded with hot-swap drive cages including 4x3.5” hot-swap backplane, 8x2.5” hot-swap backplane, and 8x2.5” SAS/PCIe SSD (NVMe) combo backplane.

5.1 4x3.5” Hot-swap Backplane

The product family supports up to two 4x3.5” backplanes capable of supporting 12 Gb/sec

SAS and 6 Gb/sec SAS / SATA or slower drives. Both hard disks and Solid State Devices (SSDs) can be supported within a common backplane. Each backplane can support either SATA or

SAS devices. However, mixing of SATA and SAS devices within a common hot-swap backplane is not supported. Systems with multiple hot-swap backplanes can support different drive type configurations as long as the drives attached to a common backplane are the same and the installed controller attached to the given backplane can support the drive type.

2. Processor throttling may occur which may impact system performance while can meet excursion spec based on CPU statistical analysis.

3. When identifying memory in the table, only Rank and Width are required. Capacity is not required.

Results may be impacted by final power direction.

4. Able to provide sufficient cooling for any PCI/e card that satisfies the 55C-200LFM boundary condition requirement.

5. Supercap uses 45C thermal spec at normal mode and 55C at fan fail mode. Excursions over spec may result in reliability impact. BBU need to meeting 45C thermal spec in both normal / fan fail mode.

6. Add-In-Card form factor PCIe SSD requires 300LFM for cooling. Performance mode in BIOS is required to be enabled.

Notes:

1. The 27°C configuration alone is limited to elevations of 900m or less. Altitude higher than 900m needs to be de-rated same as ASHRAE Class2.

2. In fan redundancy mode, 2 PSUs are required to keep the sufficient cooling. System fans and PSUs cannot fail at the same time.

3. System with 1600W PSU has higher acoustic at operation mode due to PSU own FW, it can meet Intel

Blue book.

4. Processor throttling may occur which may impact system performance while can meet excursion spec based on CPU statistical analysis.

5. When identifying memory in the table, only Rank and Width are required. Capacity is not required.

Results may be impacted by final power direction.

6. Able to provide sufficient cooling for any PCI/e card that satisfies the 55C-200LFM boundary condition requirement.

7. Supercap uses 45C thermal spec at normal mode and 55C at fan fail mode. Excursions over spec may result in reliability impact. BBU need to meeting 45C thermal spec in both normal / fan fail mode.

8. For Add-In-Card form factor PCIe SSD requires 300LFM for cooling, need to be placed in PCI slot3/4/5/6, at same time, performance mode in BIOS is required to be enabled.

9. Intel ® Xeon Phi ™ or non-Intel GPGPU cards may have performance impact during ambient excursions.

10. The backplane used in Config #2/#3 can be either SAS only hot-swap backplane or SAS/PCIe SSD

(NVMe) Combo backplane.

A power supply, after detecting a fault condition, shuts itself off. Even if the fault condition disappears, the supply does not restart unless manual or electronic intervention occurs.

Manual intervention commonly includes briefly removing and then reconnecting the supply, or using a switch. Electronic intervention can be completed by electronic signals in the Server

System.
