    Preparing for installation This document is applicable to the H3C S6825-54HF switch (BOM code: 0235A2LJ, 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

    • Lasting low relative humidity can cause washer contraction and ESD and cause problems including loose screws and circuit failure. • 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 the hardware information and specifications for the switch.

  • Page 5: Laser Safety

    • If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid. • Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices. • Use electromagnetic shielding, for example, shielded interface cables, when necessary. •...

  • Page 18: Installing And Removing A Fan Tray

    Installing and removing a fan tray CAUTION: • For adequate heat dissipation, you must install five fan trays of the same model for the switch. • Make sure all slots have a module installed when the switch is operating. • If more than one fan tray fails during switch operation, do not remove the failed fan trays simultaneously.

  • Page 19: Removing A Fan Tray

    • 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.

  • Page 31: 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 32: 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 33: 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.
