Safety information

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

General operating safety

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

· Only H3C authorized or professional engineers are allowed to operate the module.

· Keep the LCD module clean and dust-free. Do not place the module in a moist place and prevent liquid from flowing into the module.

Electrical safety

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

· Examine the work area for potential risks. For example, the server is not correctly grounded or the floor is wet.

· As a best practice, do not operate the module alone when the module is powered on.

ESD prevention

Electrostatic charges that build up on people and tools might damage or shorten the lifespan of 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.

· Take ESD prevention measures before touching any electrostatic-sensitive component.

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.

Identifying the LCD module

NOTE:

· The LCD touchable intelligent management module is also referred to as the LCD module in this document.

· Figures in this document are for illustration only.

· Software screenshots in this document are for illustration only and might change without notice.

A Liquid Crystal Display (LCD) module installed on a server allows users to view basic server information and real-time monitoring and fault information, configure the HDM network and administrator account, and restart the LCD screen. It helps users fast locate the faulty components and maintain the correct operation of each component and the server system.

The document is applicable to the following servers:

· H3C UniServer R6700 G3

· H3C UniServer R6900 G3

· H3C UniServer R8900 G3

· H3C UniServer R4700 G5

· H3C UniServer R4900 G5

· H3C UniServer R4950 G5

· H3C UniServer R6900 G5

Installation location

The installation location of the LCD module varies by server model. For more information, see the user guide for the server.

Installing the LCD module

The installation method of the LCD module varies by server model. For more information, see the user guide for the server.

Updating the LCD firmware

For more information, see H3C Servers Firmware Update Guide.

Opening or closing the LCD screen

To open the LCD screen:

1. Press the LCD screen gently. The LCD screen will pop up automatically.

2. Hold the LCD screen and slowly pull it out of the slot until it stops.

3. If the LCD module is installed vertically, rotate the screen 90 degree toward the server left.

4. If the LCD module is installed horizontally, rotate the LCD 90 degree downwards, and then rotate the screen against the server panel 90 degree clockwise.

To close the LCD screen:

1. Follow the screen opening steps in reverse, and rotate the LCD screen until it can fit into the slot.

2. Slightly press the LCD screen into the slot until you cannot push it further.

Using the LCD module

NOTE:

· The LCD screen can display a maximum of 32 characters. If the display is incomplete, access the HDM Web interface to view the complete information.

· This chapter is applicable only to LCD_FW_1.04.01_EN and later versions.

General buttons

Viewing alarm information

Perform this task to view alarm information and the health status of subsystems, including CPUs, memory, storage, fans, PCIe modules, power supplies, temperature, and others.

To view alarm information:

1. Click the Status tab and view alarm information and the health status of subsystems. The status of a subsystem is indicated by the icon color. For more information about alarm icons and subsystem icons, see Table 3 and Table 4, respectively.

Figure 3 Viewing alarm information

Table 3 Alarm status

Icon	Description
	A severe alarm is present. The system operation might be affected and service interruption might occur.
	A critical alarm is present. The server might be powered off and the system operation might be terminated. Immediate action is required.

Table 4 Subsystem status

Icon color	Description
(Green)	The subsystem is operating correctly.
(Amber)	A severe error has occurred in the subsystem and the component performance has obviously degraded.
(Red)	A critical error has occurred in the subsystem and the server might be powered off automatically to prevent component damage.

2. If a subsystem has health issues, access the HDM Web interface to view the alarm details. For more information, see the HDM user guide.

¡ For storage, PCIe modules, temperature, and others, the screen displays only components with health issues.
