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 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 until the system power 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 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 blanks 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 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 over empty module slots, including drive slots, rear PCIe slots, and 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 slots, 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 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

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 an onsite survey to make sure the cables won't affect the server rear.

The server is 2U 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.

The installation limits for a rack vary by rack depth. For more information, see Table 2. As a best practice to avoid potential issues, contact H3C support for on-site surveys.

Table 2 Installation limits for different rack depths

Rack depth	Installation limits
1000 mm (39.37 in)	· The 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. As a best practice, contact H3C Support to determine the installation site of PDUs or change PDU size. If the slide rails cannot be installed, use trays or other tools to support the server.
1100 mm (43.31 in)	Make sure the CMA does not hinder PDUs at the server rear before installing the H3C CMA. If the CMA hinders PDU installation, change a rack with larger depth or adjust the installation site of PDUs.
1200 mm (47.24 in)	Make sure the CMA does not hinder PDUs or the cabling. If the CMA hinders PDU installation or cabling, change the installation site of PDUs. For detailed installation suggestions, see Figure 1.

Replacing a SAS/SATA drive

Guidelines

The drives are hot swappable. If you hot swap an HDD repeatedly within 30 seconds, the system might fail to identify the drive.

If you are using the drives to create a RAID, follow these restrictions and guidelines:

· To build a RAID (or logical drive) successfully, make sure all drives in the RAID are the same type (HDDs or SSDs) and have the same connector type (SAS or SATA).

· For efficient use of storage, use drives that have the same capacity to build a RAID. If the drives have different capacities, the lowest capacity is used across all drives in the RAID.

· If one drive is used by several logical drives, RAID performance might be affected and maintenance complexities will increase.

· If the installed drive contains RAID information, you must clear the information before configuring RAIDs. For more information, see the storage controller user guide for the server.

To configure RAID settings after the drive is replaced, see the storage controller user guide for the server.

Prerequisites

Back up data in the RAID array.

Removing a SAS/SATA drive

1. Remove the security bezel, if any. For more information, see "Removing the security bezel."

Replacing a standard storage controller and a power fail safeguard module

WARNING!

To avoid bodily injury from hot surfaces, allow the server and its internal modules to cool before touching them.

For some storage controllers, you can order a power fail safeguard module to prevent data loss when power outage occurs.

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.

A supercapacitor has a lifespan of 3 to 5 years. If the lifespan of a supercapacitor expires, a supercapacitor exception might occur. The system notifies users of supercapacitor exceptions by using the following methods:

· For a PMC storage controller, the status of the flash card will become Abnormal_status code. You can check the status code to identify the exception. For more information, see HDM online help.

· For an LSI storage controller, the status of the flash card of the power fail safeguard module will become Abnormal.

You can also review log messages from HDM to identify supercapacitor exceptions.

For the power fail safeguard module to take effect, replace the supercapacitor before its lifespan expires.

IMPORTANT:

After the supercapacitor replacement, verify that cache related settings are enabled for logical drives. For more information, see HDM online help.

Guidelines

To install multiple storage controllers, make sure they are of the same vendor. For information about the available storage controllers and their vendors, visit the query tool at http://www.h3c.com/cn/Service/Document_Software/Document_Center/Server/.

Make sure the power fail safeguard module or supercapacitor is compatible with the storage controller. Use Table 8 to identify the compatibility and supercapacitor installation location.

Table 8 Storage controller compatibility with power fail safeguard module or supercapacitor

Storage controller	Power fail safeguard module/supercapacitor	Supercapacitor location
RAID-LSI-9361-8i(1G)-A1-X	Flash-LSI-G2-2U-2 or SCAP-LSI-G2-2U power fail safeguard module	On the air baffle
RAID-LSI-9361-8i(2G)-1-X
RAID-P460-B4	BAT-PMC-G3-2U-1 or SCAP-PMC-G3-2U supercapacitor
RAID-LSI-9460-8i(2G)	SCAP-LSI-G3-2U or BAT-LSI-G3 supercapacitor
RAID-LSI-9460-8i(4G)

HBA-H460-B1
HBA-LSI-9311-8i
HBA-LSI-9440-8i

The supercapacitor might have a low charge after the power fail safeguard module is installed or after the server is powered up. 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.

Replacing a DIMM

WARNING!

To avoid bodily injury from hot surfaces, allow the server and its internal modules to cool before touching them.

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. RDIMMs can perform parity checking on addresses. Compared with RDIMMs, LRDIMMs provide larger capacity and higher bandwidth.

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 in "Appendix A Server specifications."

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 12.

Table 12 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.

For DIMMs compatible with the server and detailed DIMM information, visit the query tool at http://www.h3c.com/cn/Service/Document_Software/Document_Center/Server/.

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 product code.

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

· 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 15. · If two processors are present, see Figure 16. · If four processors are present, see Figure 17.
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 15, Figure 16, and Figure 17. · DIMM installation schemes: ¡ If only one processor is present, see Figure 15. ¡ If two processors are present, see Figure 16. ¡ If four processors are present, see Figure 17.
Memory Rank Sparing	· A minimum of 2 ranks per channel. · DIMM installation schemes: ¡ If only one processor is present, see Figure 15. ¡ If two processors are present, see Figure 16. ¡ If four processors are present, see Figure 17.

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 15 DIMM population schemes (one processor present)

Figure 16 DIMM population schemes (two processors present)

Figure 17 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.

· Make sure all DCPMMs installed on the server have the same capacity.

· 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

Trusted platform module (TPM) is a microchip embedded in the management module. It stores encryption information (such as encryption keys) for authenticating server hardware and software. The TPM operates with drive encryption programs such as Microsoft Windows BitLocker to provide operating system security and data protection. For information about Microsoft Windows BitLocker, visit the Microsoft website at http://www.microsoft.com.

Trusted cryptography module (TCM) is a trusted computing platform-based hardware module with protected storage space, which enables the platform to implement password calculation.

Installation and setup flowchart

Figure 18 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.

· If the installed TPM/TCM is faulty, remove the system board, and contact H3C Support for system board and TPM/TCM replacement.

· 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.

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.

Replacing the system battery

WARNING!
