· Couple the racks together in multi-rack installations.

· Load the rack from the bottom to the top, with the heaviest hardware unit at the bottom of the rack.

· Get help to lift and stabilize the server during installation or removal, especially when the server is not fastened to the rails. As a best practice, a minimum of two people are required to safely load or unload a rack. A third person might be required to help align the server if the server is installed higher than check level.

· For rack stability, make sure only one unit is extended at a time. A rack might get unstable if more than one server unit is extended.

· Make sure the rack is stable when you operate a server in the rack.

ESD prevention

Electrostatic charges that build up on people and tools might damage or shorten the lifespan of the system board and electrostatic-sensitive components.

Preventing electrostatic discharge

To prevent electrostatic damage, follow these guidelines:

· Transport or store the server with the components in antistatic bags.

· Keep the electrostatic-sensitive components in the antistatic bags until they arrive at an ESD-protected area.

· Place the components on a grounded surface before removing them from their antistatic bags.

· Avoid touching pins, leads, or circuitry.

· Make sure you are reliably grounded when touching an electrostatic-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

The following are grounding methods that you can use to prevent electrostatic discharge:

· Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

· Take adequate personal grounding measures, including wearing antistatic clothing and static dissipative shoes.

· Use conductive field service tools.

· Use a portable field service kit with a folding static-dissipating work mat.

Cooling performance

Poor cooling performance might result from improper airflow and poor ventilation and might cause damage to the server.

To ensure good ventilation and proper airflow, follow these guidelines:

· Install blanks if the following module slots are empty:

¡ Drive bays.

¡ Fan bays.

¡ PCIe slots.

¡ Power supply slots.

· Do not block the ventilation openings in the server chassis.

· To avoid thermal damage to the server, do not operate the server for long periods in any of the following conditions:

¡ Access panel open or uninstalled.

¡ Air baffles uninstalled.

¡ PCIe slots, drive bays, fan bays, or power supply slots empty.

· To maintain correct airflow and avoid thermal damage to the server, install rack blanks to cover unused rack units.

Battery safety

The server's system board contains a system battery, which is designed with a lifespan of 5 to 10 years.

If the server no longer automatically displays the correct date and time, you might need to replace the battery. When you replace the battery, follow these safety guidelines:

· Do not attempt to recharge the battery.

· Do not expose the battery to a temperature higher than 60°C (140°F).

· Do not disassemble, crush, puncture, short external contacts, or dispose of the battery in fire or water.

· Dispose of the battery at a designated facility. Do not throw the battery away together with other wastes.

Installing storage controllers and power fail safeguard modules

For some storage controllers, you can order a power fail safeguard module to prevent data loss from power outages.

A power fail safeguard module provides a flash card and a supercapacitor. When a system power failure occurs, this supercapacitor can provide power for a minimum of 20 seconds. During this interval, the storage controller transfers data from DDR memory to the flash card, where the data remains indefinitely or until the controller retrieves the data.

Guidelines

The supercapacitor might have a low charge after the power fail safeguard module is installed. If the system displays that the supercapacitor has low charge, no action is required. The system will charge the supercapacitor automatically. You can view the state of the supercapacitor from the BIOS.

Each supercapacitor has a short supercapacitor cable attached to it and requires an extension cable for storage controller connection. The required extension cable varies by supercapacitor model and storage controller model. Use Table 6-1 to determine the extension cable to use.

Table 6-1 Supercapacitor extension cable selection

The server provides seven fan bays. When you configure fans, use the following guidelines:

· You must install functioning fans in all fan bays if any of the following components are installed:

¡ NVMe drives.

¡ Rear drives.

¡ GPU module.

· If none of the components listed above are used, you can leave some of the fan bays empty depending on the number of processors, as follows:

¡ If only one processor is present, you can leave fan bays 1, 2 and 4 empty, with fan bays 3, 5, 6, and 7 populated with fans.

¡ If two processors are present, you can leave fan bay 4 empty, with all the remaining fan bays populated with fans.

· If a fan bay is empty, make sure a fan blank is installed. For the locations of fans in the server, see "Fans."

The server will be powered off gracefully if any of its sensors detects that the temperature has reached the critical threshold. If the temperature of a critical component, such as a processor, exceeds the overtemperature threshold, the server is powered off immediately. You can view the detected temperatures and thresholds from the HDM Web interface.

Verifying the installation

Installing DIMMs

The server supports DCPMMs and DRAM DIMMs (both LRDIMM and RDIMM supported). Compared with DRAM DIMMs, DCPMMs provide larger capacity and can protect data from getting lost in case of unexpected system failures.

Both DCPMMs and DRAM DIMMs are referred to as DIMMs in this document, unless otherwise stated.

Guidelines

WARNING!

The DIMMs are not hot swappable.

You can install a maximum of eight DIMMs for each processor, four DIMMs per memory controller. For more information, see "DIMM slots."

For a DIMM to operate at 2933 MHz, make sure the following conditions are met:

· Use Cascade Lake processors that support 2933 MHz data rate.

· Use DIMMs with a maximum of 2933 MHz data rate.

· Install a maximum of one DIMM per channel.

The supported DIMMs vary by processor model, as shown in Table 6-3.

Table 6-3 Supported DIMMs of a processor

Processor	Supported DIMMs
Skylake	Only DRAM DIMMs.
Cascade Lake	· Only DRAM DIMMs. · Mixture of DCPMM and DRAM DIMMs.
Jintide-C series	Only DRAM DIMMs.

Guidelines for installing only DRAM DIMMs

When you install only DRAM DIMMs, follow these restrictions and guidelines:

· Make sure all DRAM DIMMs installed on the server have the same specifications.

· Make sure the corresponding processor is present before powering on the server.

· For the memory mode setting to operate correctly, make sure the following installation requirements are met when you install DRAM DIMMs for a processor:

Memory mode	DIMM slot population rules
Independent	· If only one processor is present, see Figure 6-60. · If two processors are present, see Figure 6-61.
Mirror Partial Mirror	· A minimum of two DIMMs for a processor. · This mode does not support DIMM population schemes that are not recommended in Figure 6-60 and Figure 6-61. · DIMM installation scheme: ¡ If only processor 1 is present, see Figure 6-60. ¡ If two processors are present, see Figure 6-61.
Memory Rank Sparing	· A minimum of 2 ranks per channel. · DIMM installation scheme: ¡ If only one processor is present, see Figure 6-60. ¡ If two processors are present, see Figure 6-61.

NOTE:

If the DIMM configuration does not meet the requirements for the configured memory mode, the system uses the default memory mode (Independent mode). For more information about memory modes, see the BIOS user guide for the server.

Figure 6-60 DIMM population schemes (one processor present)

Figure 6-61 DIMM population schemes (two processors present)

Guidelines for mixture installation of DCPMMs and DRAM DIMMs

When you install DRAM DIMMs and DCPMMs on the server, follow these restrictions and guidelines:

· Make sure the corresponding processors are present before powering on the server.

· Make sure all DRAM DIMMs have the same product code and all DCPMMs have the same product code.

· As a best practice to increase memory bandwidth, install DRAM and DCPMM DIMMs in different channels.

· A channel supports a maximum of one DCPMM.

· As a best practice, install DCPMMs symmetrically across the two memory processing units for a processor.

· To install both DRAM DIMM and DCPMM in a channel, install the DRAM DIMM in the white slot and the DCPMM in the black slot. To install only one DIMM in a channel, install the DIMM in the white slot if the DIMM is DCPMM.

Installing and setting up a TCM or TPM

Installation and setup flowchart

Figure 6-64 TCM/TPM installation and setup flowchart

Installing a TCM or TPM

Guidelines

· Do not remove an installed TCM or TPM. Once installed, the module becomes a permanent part of the system board.

· When installing or replacing hardware, H3C service providers cannot enable the TCM or TPM or the encryption technology. For security reasons, only the customer can enable these features.

· When replacing the system board, do not remove the TCM or TPM from the system board. H3C will provide a TCM or TPM with the spare system board for system board or module replacement.

· Any attempt to remove an installed TCM or TPM from the system board breaks or disfigures the TCM or TPM security rivet. Upon locating a broken or disfigured rivet on an installed TCP or TPM, administrators should consider the system compromised and take appropriate measures to ensure the integrity of the system data.

· H3C is not liable for blocked data access caused by improper use of the TCM or TPM. For more information, see the encryption technology feature documentation provided by the operating system.

PCIe modules

Typically, the PCIe modules are available in the following standard form factors:

· LP—Low profile.

· FHHL—Full height and half length.

· FHFL—Full height and full length.

· HHHL—Half height and half length.

· HHFL—Half height and full length.

Some PCIe modules, such as mezzanine storage controllers, are in non-standard form factors.

Storage controllers

The server supports the following types of storage controllers depending on their form factors:

· Embedded RAID controller —Embedded in the server and does not require installation.

· Mezzanine storage controller—Installed on the mezzanine storage controller connector of the system board and does not require a riser card for installation.

· Standard storage controller—Comes in a standard PCIe form factor and typically requires a riser card for installation.

For some storage controllers, you can order a power fail safeguard module to prevent data loss from power outages. This module provides a flash card and a supercapacitor. When a system power failure occurs, the supercapacitor provides power for a minimum of 20 seconds. During this interval, the storage controller can transfer data from DDR memory to the flash card, where the data remains indefinitely or until the controller retrieves the data. If the storage controller contains a built-in flash card, you can order only a supercapacitor.
