Note 1: The OCP 3.0 card is hot-pluggable. Under Red Hat Enterprise Linux 8.x, the OCP 3.0 card hot-plug LED is lit orange for several seconds after the card is hot plugged into its slot. This does not affect the normal use of the card. It is caused by the conflict between the OCP NIC 3.0 design specification and the PCIe hot-plug specification. 29 White Paper for KAYTUS KR2280V2 Series Servers_Powered by Intel Processors

NOTE
• Warning error: Errors that result in redundancy degradation or loss, and other errors that have a minor impact on the system running and that require attention. • Critical error: Errors that result in system crash/restart or part failure, and other errors that have a major impact on the system running and that require immediate attention. 5.4 Port Description Table 5-2 Port Description
Port Description
VGA Port Enables you to connect a display terminal to the system.
USB 3.0 Port Enables you to connect a USB 3.0/2.0 device to the system.
USB 2.0/LCD Port Enables you to connect a USB 2.0 device or an LCD module to the system.
USB Type-C Port Enables you to connect a USB storage device to the system for automatic log copying to the USB device and automatic configuration importing to the BMC. Note: The BMC provides USB management interfaces, for searching and configuring functions of the BMC management network port. It provides the function to enable/disable the USB management function (enabled by default), and displays the USB device access status of being connected or disconnected. Also, the BMC records operations on the USB device in the audit logs after the device is connected to the system.
System/BMC Serial Port • System serial port: enables you to capture system logs. • BMC serial port: enables you to capture BMC logs and debug the BMC.
BMC Management Network Port Enables you to manage the server. Note: It is a Gigabit Ethernet port that supports 100 Mbps and 1,000 Mbps auto-negotiation.
PSU Socket Connected through a power cord. You can select the PSUs as needed.

Compatibility Refer to the following rules to select the DDR5 DIMMs. IMPORTANT • A server must use DDR5 DIMMs with the same part number (P/N code). All DDR5 DIMMs operate at the same speed, which is the lowest of: - Memory speed supported by a specific CPU. - Maximum operating speed of a specific memory configuration. • Mixing DDR5 DIMMs of different specifications (capacity, bit width, rank, height, etc.) is not supported. • For specific memory options, consult your local sales representative or refer to 7.2 Hardware Compatibility. • DDR5 DIMMs can be used with the 4th/5th Gen Intel Xeon Scalable processors (Sapphire Rapids/Emerald Rapids). The maximum memory capacity supported is identical for different CPU models. • The maximum number of DIMMs supported varies by the CPU type, DIMM type and rank quantity. NOTE Maximum number of DIMMs supported per channel ≤ Maximum number of ranks supported per channel ÷ Number of ranks per DIMM. Table 5-4 DDR5 DIMM (4,800 MT/s) Specifications

4. Population Rules General population rules for DDR5 DIMMs: • Install DIMMs only when the corresponding processor is installed. • Install dummies in the empty DIMM slots. 35 White Paper for KAYTUS KR2280V2 Series Servers_Powered by Intel Processors Population rules for DDR5 DIMMs in specific modes: • Memory sparing mode - Follow the general population rules. - Each channel must have a valid online spare configuration. - Each channel can have a different online spare configuration. - Each channel with a DIMM installed must have a spare rank. • Memory mirroring mode - Follow the general population rules. - Each processor supports 4 integrated memory controllers (iMCs). Each iMC has 2 channels to be populated with DIMMs. Installed DIMMs must be of the same capacity and organization. - In a multi-processor configuration, each processor must have a valid memory mirroring configuration. 5. DIMM Slot Layout Up to 32 DDR5 DIMMs can be installed in a server, and a balanced DIMM configuration is recommended for optimal memory performance. DIMM configuration must be compliant with the DIMM population rules. Figure 5-14 DIMM Slot Layout

5.11 Fan Modules • The server supports 6 fan modules. Users can select 6038 or 6056 fans based on the configuration. - The 6056 fans support N+1 redundancy, which means that the server can continue working properly when a single fan fails. - The 6038 fans does not support redundancy. • The fan modules are hot-swappable. • The server supports intelligent fan speed control. • The server must use fan modules with the same part number (P/N code). 63 White Paper for KAYTUS KR2280V2 Series Servers_Powered by Intel Processors Figure 5-50 Fan Module Locations

5.12 LCD Module 5.12.1 Function The LCD module reads server-related information from the BMC, such as the operating status of processors and memories, network status, logs, and alerts, and transmits the information to client mobile terminals via Bluetooth. The LCD module synchronizes information with the BMC through I2C and can display information on an LCD screen or in the app. The server's basic information, system status and alert diagnosis can be displayed in the app via Bluetooth, facilitating the operation and maintenance. 5.12.2 Mobile Management Software ISMM As mobile management software, ISMM reads server-related information from the BMC via the LCD module, including the operating status of processors and memories, network status, logs, and alerts, and transmits the information to client mobile terminals via Bluetooth. ISMM facilitates the O&M personnel to inspect and maintain the server and delivers more comprehensive server management capabilities. 64 White Paper for KAYTUS KR2280V2 Series Servers_Powered by Intel Processors Table 5-22 Basic Features of ISMM

Notes: 1. Not all configurations support an operating temperature range of 5°C to 45°C (41°F to 113°F). The GPU configuration supports an operating temperature range of 10°C to 30°C (50°F to 86°F). 2. Standard operating temperature: - 10°C to 35°C (50°F to 95°F) is the standard operating temperature range at sea level. At an altitude of 0 to 3,050 m (0 to 10,007 ft), derate the maximum allowable temperature by 1°C per 305 m (1°F per 556 ft). No direct sustained sunlight is permitted. The maximum 81 White Paper for KAYTUS KR2280V2 Series Servers_Powered by Intel Processors temperature gradient is 20°C/h (36°F/h). Both the altitude and the maximum temperature gradient vary by server configuration. - Any fan failure or operations above 30°C (86°F) may lead to system performance degradation. 3. Expanded operating temperature: - For some configurations, the supported system inlet ambient temperature can be expanded to 5°C to 10°C (41°F to 50°F) and 35°C to 45°C (95°F to 113°F) at sea level. At an altitude of 0 to 950 m (0 to 3,117 ft), derate the maximum allowable operating temperature by 1°C per 305 m (1°F per 556 ft).

The GPU configuration supports an operating temperature range of 10°C to 30°C (50°F to 86°F). 2. Standard operating temperature: - 10°C to 35°C (50°F to 95°F) is the standard operating temperature range at sea level. At an altitude of 0 to 3,050 m (0 to 10,007 ft), derate the maximum allowable temperature by 1°C per 305 m (1°F per 556 ft). No direct sustained sunlight is permitted. The maximum temperature gradient is 20°C/h (36°F/h). Both the altitude and the maximum temperature gradient vary by server configuration. - Any fan failure or operations above 30°C (86°F) may lead to system performance degradation. 3. Expanded operating temperature: - For some configurations, the supported system inlet ambient temperature can be expanded to 5°C to 10°C (41°F to 50°F) and 35°C to 45°C (95°F to 113°F) at sea level.
