  • Page 8: Preparing For Installation

    Preparing for installation The H3C S6850 Switch Series includes the following models: • S6850-56HF. • S6850-2C. The H3C S9850 Switch Series includes the following models: • S9850-4C. • S9850-32H. Safety recommendations To avoid any equipment damage or bodily injury caused by incorrect use, read the following safety recommendations before installation.

  • Page 9: Temperature/Humidity

    Temperature/humidity Maintain appropriate temperature and humidity in the equipment room. • Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of materials, and metal corrosion. • Lasting low relative humidity can cause washer contraction and ESD and cause problems including loose mounting screws and circuit failure.

  • Page 10: Laser Safety

    To prevent EMI, use the following guidelines: • 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.

  • Page 28: Attaching The Slide Rails To The Rack

    To connect the grounding cable to a grounding point on the left panel: Choose a grounding point as required. When you install the mounting brackets at the port-side mounting position, choose the auxiliary grounding point. When you install the mounting brackets at the power module-side mounting position, choose the primary grounding point.

  • Page 29: Mounting The Switch In The Rack

    Identify the slide rail installation position in the rack. Install cage nuts (user-supplied) in the mounting holes in the rack posts. Align the screw holes in one slide rail with the cage nuts in a rear rack post. Use user-supplied M6 screws to attach the slide rail to the post (recommended torque: 30 kgf-cm).
  • Page 30 IMPORTANT: • If you use long slide rails to rack-mount the S6850-56HF, make sure the front ends of the long slide rails reach out of the chassis rails for a maximum of 20 mm (0.79 in). If you use super-short slide rails to rack-mount the S6850-56HF, make sure the front ends of the super-short slide rails reach inside the chassis rails for a minimum of 90 mm (3.54 in) after installation.

  • Page 52: 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 53: Identifying Physical Irf Ports On The Member Switches

    Figure 68 IRF fabric in ring topology IRF-port2 IRF-port1 IRF-port2 IRF-port1 IRF-port1 IRF-port2 You can set up IRF links between S6850/S9850 switches as follows: • Use a QSFP28 module and fiber or a QSFP28 cable to connect QSFP28 ports for a 100-GE IRF physical connection.

  • Page 54: Planning The Cabling Scheme

    Planning the cabling scheme You can use QSFP28/QSFP+ cables, or QSFP28/QSFP+ transceiver modules and fibers to connect the S6850/S9850 switches for IRF connections. If the switches are all in one equipment room, choose QSFP28/QSFP+ cables for IRF connections. If the switches are far away from one another, choose QSFP28/QSFP+ transceiver modules and fibers for IRF connections.

  • Page 55: Configuring Basic Irf Settings

    Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and the remote network management station can reach each other. Use Telnet or SNMP to access the IRF fabric from the network management station. (See H3C S6850 & S9850 Switch Series Fundamentals Configuration Guide.) Verify that you can manage all member switches as if they were one node.
  • Page 56 To avoid IP address collision and network problems, configure at least one multi-active detection (MAD) mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more information about MAD detection, see H3C S6850 & S9850 Switch Series IRF Configuration Guide.
