Page 15: Installing/Removing Liquid-Cooled Transceiver Modules
Installing/removing liquid-cooled transceiver modules Installing a liquid-cooled transceiver module IMPORTANT: You must use dedicated liquid-cooled transceiver modules for the switch. To install a liquid-cooled transceiver module: Wear rubber gloves to avoid direct contact with the coolant. Remove the dust cap from the target fiber port. As shown in Figure2-20, grasp the transceiver module between your thumb and index finger and correctly orient it. -
Page 16: Connecting/Disconnecting Liquid-Cooled Cables
As shown in Figure2-21, putting your forefinger into the pull ring, pull the transceiver module straight out of the fiber port. If you use force at an angle, you can hardly pull the transceiver module out and the transceiver module or fiber port might be damaged. To avoid damaging the pull ring, use even force to pull the transceiver module out. -

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. For more information, see 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. -

Page 24: Setting Up An Irf Fabric
Setting up an IRF fabric You can use H3C IRF technology to connect and virtualize multiple S6850-56HF-IM switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability. IRF fabric setup flowchart... -
Page 25: Planning Irf Fabric Setup
The switching capacity of an IRF fabric equals the total switching capacities of all member switches. An S6850-56HF-IM switch can set up an IRF fabric with switches from the S6850 switch series. Reserve sufficient space in the tank for installation of the devices. - Page 26 When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch. The IRF port connections in the two figures are for illustration only, and more connection methods are available.
