Preparing for installation This document is applicable to the H3C S6825-54HF switch (product code: LS-6825-54HF). Safety recommendations To avoid any equipment damage or bodily injury caused by incorrect use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.
• High temperature can accelerate the aging of insulation materials and significantly lower the reliability and lifespan of the switch. For the temperature and humidity requirements of different switch models, see H3C S6825 Switch Series Hardware Information and Specifications. Cleanliness Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in poor contact of metal connectors and contact points.
CAUTION: As a best practice, control the corrosive gas concentrations in the equipment room at their average values. Make sure the corrosive gas concentrations do not exceed 30 minutes per day at their maximum values. To control corrosive gases, use the following guidelines: •...
Installation tools No installation tools are provided with the switch. Prepare the following tools yourself: • Phillips screwdriver. • Flathead screwdriver. • ESD wrist strap. • Marker. Installation accessories Before installation, make sure you have all the required installation accessories. If any accessory is damaged or missing, use the part No.

Installing the switch CAUTION: Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open the chassis, contact H3C for permission. Otherwise, H3C shall not be liable for any consequence caused thereby. CAUTION: When installing the switch, always wear an ESD wrist strap and make sure the wrist strap makes good skin contact and is reliably grounded.

Use M5 grounding screws to attach a grounding cable that has a two-hole grounding lug or single-hole grounding lug to the grounding point on the switch. If the grounding cable length or terminal type cannot meet your requirement, make an applicable grounding cable or contact H3C Support.
Attaching the slide rails to the rack IMPORTANT: M6 screws and cage nuts are used to attach the slide rails to the rack. Prepare M6 screws and cage nuts yourself. As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws. Before mounting the switch in the rack, you must attach slide rails to the rack.

Attach cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as the slide rails. One person performs the following operations: a. Supporting the bottom of the switch, aligns the chassis rails with the slide rails on the rack posts.

As a best practice, make sure the power supplies and fan trays on the switch have the same airflow direction. For the fan trays available for the switch and their specifications, see H3C S6825 Switch Series Hardware Information and Specifications. Installing a fan tray CAUTION: To prevent damage to the fan tray or the connectors on the backplane, insert the fan tray gently.
• Do not touch any bare wires and terminals on a fan tray. • Do not place a fan tray in a moist location or let liquid flow into it. • Contact H3C Support if the circuits or components on a fan tray are faulty. Do not remove any fan tray components.
As a best practice, install two power supplies of the same model for the switch. Select power supplies for the switch as required. For the power supplies available for the switch and their specifications, see H3C S6825 Switch Series Hardware Information and Specifications. Precautions •...
The installation procedure is the same for different models of power supplies. The following procedure installs a PSR450-12A power supply. To install a power supply: Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. Unpack the power supply and verify that the power supply model is correct.

Removing a PSR450-12A/PSR450-12A1 power supply The removal procedure is the same for the PSR450-12A and PSR450-12A1 power supplies. The following procedure removes a PSR450-12A power supply. To remove a PSR450-12A power supply: Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. Remove the power cord.
Figure2-29 Removing the power cord from the power supply Hold the handle of the power supply with one hand, press the latch on the power supply towards the handle direction with your thumb, and pull the power supply part way out of the slot. Supporting the power supply bottom with the other, slowly pull the power supply out of the slot along the guide rails.
Connecting the power cord for a PSR450-12A/PSR450-12A1 power supply Insert the female connector of the power cord supplied with the power supply into the power receptacle on the power supply. Use a releasable cable tie to secure the power cord to the handle of the power supply, as shown in Figure2-31.

The signal pinout for the RJ-45 connector of a serial console cable varies by vendor. To avoid abnormal configuration terminal display, use a serial console cable provided by H3C as shown in Table3-2. To prepare a serial console cable yourself, make sure the signal pinout for the RJ-45 connector is the same as that shown in Table3-3.
Click the following link, or copy it to the address bar on your browser and download the USB-to-RJ45 console driver. http://www.h3c.com/en/home/USB_to_RJ45_Console/ View the TXT file named Read me in the Windows folder to check whether the Windows system of the configuration terminal supports the driver.

After the startup completes, you can access the CLI to configure the switch. For more information about the configuration commands and CLI, see H3C S6805 & S6825 & S6850 & S9850 Switch Series Configuration Guides and H3C S6805 & S6825 & S6850 &...
Setting up an IRF fabric You can use H3C IRF technology to connect and virtualize multiple switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability. The switch can set up an IRF fabric only with switches from the same switch series.
IRF member switches will automatically elect a master. You can affect the election result by assigning a high member priority to the intended master switch. For more information about master election, see IRF configuration in H3C S6805 & S6825 & S6850 & S9850 Switch Series Virtual Technologies Configuration Guide.
Planning IRF topology and connections You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Rather, the IRF fabric changes to a daisy chain topology without interrupting network services.
If the IRF member switches are all in one equipment room, use QSFP+/QSFP28 copper or fiber cables. For more information about transceiver modules and cables available for the switch, see H3C S6825 Switch Series Hardware Information and Specifications. The following subsections describe several H3C recommended IRF connection schemes by using QSFP28 transceiver modules and optical fibers, QSFP28 copper cables, and QSFP28 fiber cables.

The status LED on a power supply is not steady green (active state) or flashing green (standby state). You can use the status LED on a power supply to identify a power supply failure. For more information about the status LED on a power supply, see H3C PSR450 Power Module Series User Manual. Solution To resolve the issue: Verify that the power cord is correctly connected.

Stop bits—1. Parity—None. Flow control—None. If the issue persists, contact H3C Support. Garbled display on the configuration terminal Symptom The configuration terminal displays garbled text when the switch is powered on. Solution To resolve the issue: Verify that the terminal parameter settings are correct: Baud rate—9600.
