As a best practice, use H3C transceiver modules and cables for the switch. H3C transceiver modules and cables are subject to change over time. For the most up-to-date list of H3C transceiver modules and cables, contact H3C Support or marketing staff. For information about the specifications and views of H3C transceiver modules and cables, see H3C Transceiver Modules User Guide.

USB port
The switch has one OHCI-compliant USB 2.0 port that can upload and download data at a rate up to 480 Mbps. You can use this USB port to access the file system on the Flash of the switch, for example, to upload or download application and configuration files.
The USB port supplies power as per USB 2.0 specifications. Use only USB 2.0-compliant USB devices for the USB port. The port might not identity USB devices that are not compliant with USB 2.0.
|
|
NOTE: USB devices from different vendors vary in compatibilities and drivers. H3C does not guarantee correct operation of USB devices from other vendors on the switch. If a USB device fails to operate on the switch, replace it with one from another vendor. |

NOTE: · You can use a QSFP-40G-SR4-MM850 or QSFP-40G-CSR4-MM850 transceiver module to connect a QSFP+ port to four SFP+ ports. The QSFP+ transceiver module and SFP+ transceiver modules to be connected must be the same in specifications, including central wavelength and fiber type. · MPO connectors include physical contact (PC) connectors with a flat-polished face and angle-polished contact (APC) connectors with an angle-polished face (8°). |

IMPORTANT: An SFP28 port does not support speed and duplex autonegotiation. To connect an SFP28 port to a peer interface, you must execute the speed and duplex full commands on both interfaces. Configure the same speed and duplex mode for the two interfaces and the speed must be the same as that of the transceiver module or cable installed in the interface. |

5 Cooling system
|
|
CAUTION: The chassis and power supplies use separate air aisles. Make sure the two aisles are not blocked when the switch is operating. |
To dissipate heat timely and ensure system stability, the switch uses the front-rear air aisle cooling system. Consider the site ventilation design when you plan the installation site for the switch.
