Page 27: Connecting The Grounding Cable To The Chassis
• If the grounding cable length or terminal type cannot meet your requirement, make an applicable grounding cable or contact H3C Support. • If you use a grounding point on the side panel to ground the switch, connect the grounding cable to the grounding point before installing the switch in the rack. - Page 28 For an LS-6850-56HF, LS-6850-56HF-H1, S6850-56HF-SAN, S6850-2C, or S9850-32H switch, the primary grounding point and auxiliary grounding point are on the left side panel. Both grounding points support a grounding cable that has a single-hole lug or dual-hole lug. Use M5 grounding screws to attach the grounding cable to the switch.

Page 40: Installing A Power Module
• To avoid power module damage, do not open the power module. When an internal circuit or component of the power supply fails, contact H3C Support. Installing a power module CAUTION: • Follow the forward inertia of the power module when inserting it into the chassis, and make sure the power module has firm contact with the connectors on the backplane. -

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 H3C S6805 & S6825 & S6850 & S9850 Switch Series Virtual Technologies Configuration Guide. -
Page 56: 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. -

QSFP28/QSFP+ transceiver modules and fibers for IRF connections. For more information about available cables, see H3C S6850 & S9850 Switch Series Hardware Information and Specifications. The following subsections describe several IRF connection schemes by using the QSFP28 cables and QSFP28 transceiver modules and fibers. -

Connecting the physical IRF ports CAUTION: Wear an ESD wrist strap when you install transceiver modules, fibers, and cables. -
Page 60: Accessing The Irf Fabric To Verify The Configuration
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 S6805 & S6825 & S6850 & S9850 Switch Series Fundamentals Configuration Guide.) Verify that you can manage all member switches as if they were one node. -

The status LED on a FAN-40B-1-C or FAN-40F-1-D fan tray is steady red and the system outputs alarm messages. Solution "Installing/removing fan trays" to replace the fan tray. If the problem persists, contact H3C Support. Configuration terminal display problems No display Symptom The configuration terminal displays nothing when the switch is powered on.
