Page 3: Preparing For Installation
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. -
Page 4: Cleanliness
• 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. -

Page 16: Attaching The Slide Rails To The Rack
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. - Page 17 Attach cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as the slide rails.

Page 33: Setting Up An Irf Fabric
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. -
Page 34: Planning Irf Fabric Setup
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. -
Page 35: Planning Irf Topology And Connections
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. -
Page 36: Identifying Physical Irf Ports On The Member Switches
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. - Page 37 Figure4-4 Connecting the switches in one rack Figure4-5 IRF fabric topology IRF-port2 IRF-port1 IRF-port2 IRF-port1 IRF-port2 IRF-port1 IRF-port2 IRF-port1 Connecting the IRF member switches in a ToR solution You can install IRF member switches in different racks side by side to deploy a top of rack (ToR) solution.

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. - Page 40 Stop bits—1. Parity—None. Flow control—None. If the issue persists, contact H3C Support.
