Power source recommendations

Power instability or outage might cause data loss, service disruption, or damage to the server in the worst case.

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.

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

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

· 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 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 until the system LED turns into steady amber, 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 four people are required to safely load or unload a rack. A fifth 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 blanks to fill empty rack units.

ESD prevention

Electrostatic charges that build up on people and tools might damage or shorten the lifespan of boards, the midplane, 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, static dissipative shoes, and antistatic gloves.

· 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:

¡ Compute module slots.

¡ Drive bays.

¡ Rear riser card 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.

¡ Riser cards uninstalled.

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

· If the server is stacked in a rack with other devices, make sure there is a minimum clearance of 2 mm (0.08 in) below and above the server.

Battery safety

The server's management module 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

Prepare a rack that meets the rack requirements and plan an installation site that meets the requirements of space and airflow, temperature, humidity, equipment room height, cleanliness, and grounding.

Rack requirements

IMPORTANT:

As a best practice to avoid affecting the server chassis, install power distribution units (PDUs) with the outputs facing backwards. If you install PDUs with the outputs facing the inside of the server, please perform onsite survey to make sure the cables won't affect the server rear.

The server is 4U high. The rack for installing the server must meet the following requirements:

· A standard 19-inch rack.

· A clearance of more than 50 mm (1.97 in) between the rack front posts and the front rack door.

· A minimum of 1200 mm (47.24 in) in depth as a best practice. For installation limits for different rack depth, see Table 2.

Table 2 Installation limits for different rack depths

Rack depth	Installation limits
1000 mm (39.37 in)	· H3C cable management arm (CMA) is not supported. · A clearance of 60 mm (2.36 in) is reserved from the server rear to the rear rack door for cabling. · The slide rails and PDUs might hinder each other. Perform onsite survey to determine the PDU installation location and the proper PDUs. If the PDUs hinder the installation and movement of the slide rails anyway, use other methods to support the server, a tray for example.
1100 mm (43.31 in)	Make sure the CMA does not hinder PDU installation at the server rear before installing the CMA. If the CMA hinders PDU installation, use a deeper rack or change the installation locations of PDUs.

Installing storage controllers and power fail safeguard modules

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

Make sure the power fail safeguard module is compatible with its connected storage controller. For the compatibility matrix, see "Storage controllers."

The supercapacitor might have a low charge after the power fail safeguard module is installed or after the server is powered on. If the system displays that the supercapacitor has low charge, no action is required. The system will charge the supercapacitor automatically.

Install storage controllers only in PCIe slots on riser card 1.

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, 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 only 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.

· Make sure the number of ranks per channel does not exceed eight.

· For the memory mode setting to take effect, 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 61. · If two processors of model 6xxx or 8xxx are present, see Figure 62. · If two processors of model 5xxx are present, see Figure 63. · If four processors are present, see Figure 64.
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 61, Figure 62, Figure 63, and Figure 64. · If only one processor is present, see Figure 61. · If two processors of model 6xxx or 8xxx are present, see Figure 62. · If two processors of model 5xxx are present, see Figure 63. · If four processors are present, see Figure 64.
Memory Rank Sparing	· A minimum of 2 ranks per channel. · If only one processor is present, see Figure 61. · If two processors of model 6xxx or 8xxx are present, see Figure 62. · If two processors of model 5xxx are present, see Figure 63. · If four processors are present, see Figure 64.

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 61 DIMM population schemes (one processor present)

Figure 62 DIMM population schemes (two processors of model 6xxx or 8xxx present)

Figure 63 DIMM population schemes (two processors of model 5xxx present)

Figure 64 DIMM population schemes (four 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 security bezel, if any. For more information, see "Replacing the security bezel."

¡ In the GUI of a windows OS, click the Start icon in the bottom left corner, enter msinfo32 in the search box, and then click the msinfo32 item.

¡ In the CLI of a Linux OS, execute the cat /proc/meminfo command.

· Log in to HDM. For more information, see HDM online help.

· Access the BIOS. For more information, see the BIOS user guide for the server.

If the memory size is incorrect, re-install or replace the DIMM.

NOTE:

It is normal that the CLI or GUI of the server OS displays a smaller memory size than the actual size if the mirror or memory rank sparing memory mode is enabled. In this situation, you can verify the memory size from HDM.

Installing and setting up a TCM or TPM

Installation and setup flowchart

Figure 67 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 management module.

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

· Any attempt to remove an installed TCM or TPM from the management module 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.

Procedure

The installation procedure is the same for a TPM and a TCM. The following information uses a TPM to show the procedure.

To install a TPM:

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

2. Disconnect all the cables from the management module.

3. Remove the management module. For more information, see "Removing the management module."

Enabling the TCM or TPM in the BIOS

By default, the TCM and TPM are enabled for a server. For more information about configuring the TCM or TPM from the BIOS, see the BIOS user guide for the server.

You can log in to HDM to verify that the TCM or TPM is operating correctly. For more information, see HDM online help.

Configuring encryption in the operating system

For more information about this task, see the encryption technology feature documentation that came with the operating system.

The recovery key/password is generated during BitLocker setup, and can be saved and printed after BitLocker is enabled. When using BitLocker, always retain the recovery key/password. The recovery key/password is required to enter Recovery Mode after BitLocker detects a possible compromise of system integrity or firmware or hardware change.

For security purposes, follow these guidelines when retaining the recovery key/password:

· Always store the recovery key/password in multiple locations.

· Always store copies of the recovery key/password away from the server.

· Do not save the recovery key/password on the encrypted hard drive.

For more information about Microsoft Windows BitLocker drive encryption, visit the Microsoft website at http://technet.microsoft.com/en-us/library/cc732774.aspx.

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 require PCIe I/O resources. Make sure the number of such installed PCIe modules does not exceed eleven.

Storage controllers

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.

The following storage controllers require PCIe I/O resources.

Riser cards

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

The PCIe slots in a riser card are numbered differently depending on the riser card model and the PCIe riser connector or bay that holds the riser card.

Riser card guidelines

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

If a processor is faulty or absent, the corresponding PCIe slots are unavailable.

Fan modules

The server must be configured with six hot swappable fan modules, each of which includes two fans. Figure 168 shows the layout of the fan modules in the chassis.

The fans support N+1 redundancy.

During system POST and operation, the server will be powered off through HDM if the temperature detected by any sensor in the server reaches the critical threshold. The server will be powered off directly if any key components such as processors exceed the upper threshold.

Figure 168 Fan module layout

Air baffles

Compute module air baffles

Each compute module comes with two bilateral air baffles (a right air baffle and a left air baffle). You must install a low mid air baffle, high mid air baffle, or GPU module air baffle as required.

Table 32 lists air baffles available for a compute module and their installation locations and usage scenarios.

Table 32 Compute module air baffles

Name	Picture	Installation location	Usage scenario
High mid air baffle		Above the DIMMs between the two processors.	No riser card is installed in the compute module.

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.

General environment requirements
