Appendix B  Component specifications

For components compatible with the server and detailed component information, use the component compatibility lookup tool at http://www.h3c.com/en/home/qr/default.htm?id=66.

About component model names

The model name of a hardware option in this document might differ slightly from its model name label.

A model name label might add a prefix or suffix to the hardware-coded model name for purposes such as identifying the matching server brand or applicable region. For example, the DDR5-4800-32G-1Rx4 memory model represents memory module labels including UN-DDR5-4800-32G-1Rx4-R, UN-DDR5-4800-32G-1Rx4-F, and UN-DDR5-4800-32G-1Rx4-S, which have different prefixes and suffixes.

DIMMs

The server provides eight DIMM channels per processor and each channel has two DIMM slots. If the server has one processor, the total number of DIMM slots is 16. If the server has two processors, the total number of DIMM slots is 32. For the physical layout of DIMM slots, see "DIMM slots."

DRAM DIMM rank classification label

A DIMM rank is a set of memory chips that the system accesses while writing or reading from the memory. On a multi-rank DIMM, only one rank is accessible at a time.

To determine the rank classification of a DIMM, use the label attached to the DIMM, as shown in Figure 18.

Riser cards

To expand the server with PCIe modules, install riser cards on the PCIe riser connectors.

Riser card guidelines

Each PCIe slot in a riser card can supply a maximum of 75 W of power to the PCIe module. You must connect a separate power cord to the PCIe module if it requires more than 75 W of power.

If a processor is faulty or absent, the PCIe slots connected to it are unavailable.

The slot number of a PCIe slot varies by the PCIe riser connector that holds the riser card. For example, slot 1/4 represents PCIe slot 1 if the riser card is installed on connector 1 and represents PCIe slot 4 if the riser card is installed on connector 2. For information about PCIe riser connector locations, see "Rear panel view."

Appendix C  Managed removal of OCP network adapters

Before you begin

Before you perform a managed removal of an OCP network adapter, perform the following tasks:

·     Use the OS compatibility query tool at http://www.h3c.com/en/home/qr/default.htm?id=66 to obtain operating systems that support managed removal of OCP network adapters.

·     Make sure the BIOS version is 6.30.17 or higher, the HDM2 version is 1.21 or higher, and the CPLD version is V007 or higher.

Performing a hot removal

This section uses an OCP network adapter in slot 16 as an example.

To perform a hot removal:

1.     Access the operating system.

2.     Execute the dmidecode -t 9 command to search for the bus address of the OCP network adapter. As shown in Figure 60, the bus address of the OCP network adapter in slot 16 is 0000:31:00.0.

Figure 60 Searching for the bus address of an OCP network adapter by slot number

 

3.     Power off the OCP network adapter by executing the echo 0 > /sys/bus/pci/slots/slot number/power command, where slot number represents the number of the slot where the OCP network adapter resides.

Figure 61 Executing the echo 0 > /sys/bus/pci/slots/slot number/power command

 

4.     Identify whether the OCP network adapter has been disconnected:

¡     Observe the OCP network adapter LED. If the LED is off, the OCP network adapter has been disconnected.

¡     Execute the lspci vvv s 0000:31:00.0 command. If no output is displayed, the OCP network adapter has been disconnected.

Figure 62 Identifying OCP network adapter status

 

5.     Re-insert the OCP network adapter.

6.     Power on the OCP network adapter by executing the echo 1 > /sys/bus/pci/slots/slot number/power command, where slot number represents the number of the slot where the OCP network adapter resides.

7.     Identify whether the OCP network adapter has been connected:

¡     Observe the OCP network adapter LED. If the LED is on, the OCP network adapter has been connected.

¡     Execute the lspci vvv s 0000:31:00.0 command. If an output is displayed, the OCP network adapter has been connected.

8.     Identify whether any exception exists. If any exception occurred, contact H3C Support.


Appendix D  Environment requirements

About environment requirements

The operating temperature requirements for the server vary depending on the server model and hardware configuration. When the general and component-based requirements conflict, use the component-based requirement.

Be aware that the actual maximum operating temperature of the server might be lower than what is stated because of poor site cooling performance. In a real data center, the server cooling performance might decrease because of adverse external factors, including poor cabinet cooling performance, high power density inside the cabinet, or insufficient spacing between devices.

Operating temperature requirements

The cooling capability of the server depends on the power density of devices within the cabinet, the cooling capability of the cabinet, and the spacing between the server and other devices. When the server is stacked with other devices, the ventilation of the top vent holes of the server might be affected, which can potentially decrease the maximum operating temperature of the server.

Operating temperature requirements without liquid-cooled module

If the other devices are positioned above or below the server inside the cabinet, the maximum operating temperature might be reduced depending on the cooling conditions of the server, power density inside the cabinet, and cabinet cooling capability.

When a single FAN-8038-2U-G6 fan module fails or a single rotor in the FAN-8056-2U-G6 fan module fails, the following might occur:

·     The maximum server operating temperature decreases by 5°C (41°F).

·     The GPU performance might decrease.

·     The performance of processors with a TDP of more than 165 W might decrease.
