To protect the server from unstable power or power outage, use uninterrupted power supplies (UPSs) to provide power for the server.

Installation safety recommendations

To avoid bodily injury or damage to the server, read the following information carefully before you operate the server.

General operating safety

To avoid bodily injury or damage to the server, follow these guidelines when you operate the server:

· Only H3C authorized or professional server engineers are allowed to install, service, repair, operate, or upgrade the server.

· Place the server on a clean, stable table or floor for servicing.

· Make sure all cables are correctly connected before you power on the server.

· To avoid being burnt, allow the server and its internal modules to cool before touching them.

If you put the server in standby mode (system power LED in amber) with the power on/standby button on the front panel, the power supplies continue to supply power to some circuits in the server. To remove all power for servicing safety, you must first press the button, wait for the system to enter standby mode, and then remove all power cords from the server.

To avoid bodily injury or damage to the server, follow these guidelines:

· Always use the power cords that came with the server.

· Do not use the power cords that came with the server for any other devices.

· Power off the server when installing or removing any components that are not hot swappable.

Rack mounting recommendations

To avoid bodily injury or damage to the equipment, follow these guidelines when you rack mount a server:

· Mount the server in a standard 19-inch rack.

· Make sure the leveling jacks are extended to the floor and the full weight of the rack rests on the leveling jacks.

· 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.

· To maintain correct airflow and avoid thermal damage to the server, use blank panels to fill empty rack units.

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 separate 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.

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.

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.

Preparing for installation

Installing storage controllers and power fail safeguard modules

To prevent data loss when power outage occurs, you can use a power fail safeguard module.

A power fail safeguard module provides a flash card and a supercapacitor. When a system power failure occurs, this supercapacitor provides 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 status 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 to determine the extension cable to use.

Table 6 Supercapacitor extension cable selection

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 12 DIMMs for each processor, six DIMMs per memory controller. For more information about DIMMs, 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 8.

Table 8 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 requirements
Independent	· If only one processor is present, see Figure 81. · If two processors are present, see Figure 82.
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 81 and Figure 82. · DIMM installation scheme: ¡ If only processor 1 is present, see Figure 81. ¡ If two processors are present, see Figure 82.
Memory Rank Sparing	· A minimum of 2 ranks per channel. · DIMM installation scheme: ¡ If only one processor is present, see Figure 81. ¡ If two processors are present, see Figure 82.

NOTE:

If the DIMM configuration does not meet the requirements in 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 81 DIMM population schemes (one processor present)

Figure 82 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.

Procedure

1. Power off the server. For more information, see "Powering off the server."

2. Remove the server from the rack. For more information, see "Removing the server from a rack."

Installing and setting up a TCM or TPM

Installation and setup flowchart

Figure 85 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.
