IMPORTANT: · Due to compatibility and driver differences among USB devices of different manufacturers, H3C does not guarantee that USB devices from all manufacturers will function normally on this series of switches. If a USB device is not functioning properly, it is not due to a switch fault. Try using a USB device from a different manufacturer. · The USB port on the switch is designed to output current strictly in accordance with the USB 2.0 standard. Use USB storage devices that fully comply with USB 2.0 standards. If the USB storage device you use does not fully comply with the USB 2.0 standard, the USB port of this switch might fail to recognize the USB device. |

|
Operating mode |
· When using an SFP28 cable or SFP+ cable to connect an SFP28 port to the peer end, if the peer end does not support rate and duplex auto-negotiation, execute the speed and duplex full commands on both ends. For the port to come up, make sure the rate configured by the speed command must match the rate of the transceiver module. · When you use an SFP module other than SFP-GE-T and SFP-GE-T-D on a SFP28 port to establish a connection, disable autonegotiation on the remote end. · For more information about configuration restrictions and guidance for SFP28 ports, see Layer 2 — LAN Switching Configuration Guide. |
|
Available transceiver modules and cables |
Supports 25G SFP28 modules/cables, 10G SFP+ modules/cables, and 1G SFP modules NOTE: · For more information about the transceiver modules and cables supported by a SFP28 port, see H3C S6850 & S9850 Switch Series Transceiver Module Compatibility Matrixes. · Use BIDI optical modules in pairs. For example, if one end uses SFP-XG-LX-SM1270-BIDI, use FP-XG-LX-SM1330-BIDI at the other end. · The maximum transmission distance of the SFP-25G-SR-MM850 module varies by the enabling status of the FEC negotiation feature. For more information, see Table6-5. For more information about FEC negotiation, see Layer 2—LAN Switching Configuration Guide. |
|
Other restrictions and guidelines |
You can use a maximum of four long-distance SFP+ transceiver modules of the following models on a device: · SFP-XG-LH40-SM1550 · SFP-XG-LH40-SM1550-D · SFP-XG-LH80-SM1550 · SFP-XG-LH80-SM1550-D Only the 1G rate is supported on a port installed with the SFP-GE-T or SFP-GE-T-D module. When a device uses the SFP-GE-T/SFP-GE-T-D module to connect to the peer end, the peer port might come online before the local port comes online, resulting in packet loss. As a best practice to avoid the issue mentioned above, use dynamic aggregation if you are to aggregate the links between the device and a remote device. |

8 Cooling system
The S6850-56HF-CP cold plate liquid-cooled Ethernet switch employs both a cold plate and fan trays to remove all heat from the switch and thus significantly reduce the number of required air conditioners.
· The liquid cooling system uses a cold plate to directly exchange heat with the casings of high-power consumption components such as chips. It utilizes a CDU to provide circulation power, allowing the flowing water to carry the heat out of the equipment room.
· The liquid cooling system provides circulation power through the switch's own cooling fans, and with powerful cooling fans, it removes the heat from low-power consumption components within the switch from the equipment room.
For more information about the cold plate-based liquid-cooled system of the S6850-56HF-CP Ethernet switch, see H3C Cold Plate-Based Liquid-Cooled System User Guide.
