CAUTION: · Select fan trays and power supplies with airflow directions that meet the ventilation requirements at the installation site. As a best practice, make sure the power supplies and fan trays have the same airflow direction. · Do not install fan trays of different models on the same switch. To guarantee adequate heat dissipation, install five fan trays of the same model on the switch. · As a best practice, install two power supplies on the switch for 1+1 redundancy. · The switch supports mixed installation of power supplies consistent in the output power and airflow direction. These power supplies are PSR450-12A1, PSR450-12AHD, and PSR450-12D. |

USB port
The switch has one OHC-compliant USB2.0 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 file system of the switch, for example, to upload or download application and configuration files.
IMPORTANT: · USB devices from different vendors vary in compatibility and driver. H3C does not guarantee correct operation of all USB devices on the switch. If a USB device fails to operate on the switch, replace it with one from another vendor. · The USB port on the switch is designed to output current in strict accordance with the USB 2.0 standard. For a USB storage device to be identified by the USB port, make sure the USB device fully complies with USB 2.0. |
SFP28 port
The switch provides 48 SFP28 ports. The SFP28 ports support the following transceiver modules and cables:
· 25-GE SFP28 transceiver modules in Table4-5.
· SFP28 copper cables in Table4-6.
· SFP28 fiber cables in Table4-7.
· 10-GE SFP+ transceiver modules in Table4-8.
· SFP+ copper cables in Table4-9.
· SFP+ fiber cables in Table4-10.
· 1-GE SFP transceiver modules in Table4-11.
IMPORTANT: When connecting an SFP28 port on the switch to a peer port, follow these guidelines: · To use an SFP28 or SFP+ copper cable, you must configure the speed and the duplex mode for the SFP28 port and the peer port if the peer port does not support autonegotiation of the speed and duplex mode. To configure the speed and the duplex mode, execute the speed and duplex full commands. · To use an SFP transceiver module except for an SFP-GE-T or SFP-GE-T-D transceiver module, make sure the autonegotiation feature is disabled on the peer port. · For more information about SFP28 port configurations, see Ethernet interface Configuration in H3C S6825 Switch Series Layer 2—LAN Switching Configuration Guide. |

CAUTION: · Use BIDI transceiver modules in matched pair. For example, if one end uses an SFP-XG-LH80-SM1490-BIDI transceiver module, the other end must use an SFP-XG-LH80-SM1550-BIDI transceiver module. · Installed with an SFP-GE-T or SFP-GE-T-D transceiver module, an SFP28 port can operate only at 1 Gbps. · If the switch uses an SFP-GE-T or SFP-GE-T-D transceiver module to connect to the peer device, the peer interface comes up before the local interface when the device reboots, which causes packet loss. As a best practice, configure dynamic link aggregation to avoid such an issue if the switch is connected to the peer device through an aggregate link. |
QSFP28 port
Release 6635 and later versions support port splitting. On an S6825-54HF switch, only interfaces numbered 27 and 28 can be split into four 10GE or 25GE interfaces.

· 100-GE QSFP28 transceiver modules in Table4-12.
· QSFP28 copper cables in Table4-13.
· QSFP28 fiber cables in Table4-14.
· QSFP28 to 4 × 25G SFP28 copper cables in Table4-15.
