The S6825-54HF switch has a serial label pull tab on the rear panel. It provides the ESN and MAC address of the switch.

The switch comes with power supply slot PWR1 empty and power supply slot PWR2 installed with a filler panel. In Figure2-2, two PSR450-12A power supplies are installed on the switch.

The switch comes with the five fan tray slots empty. You must install five fan trays of the same model for the switch. In Figure2-2, five LSPM1FANSA fan trays are installed on the switch.

The S6825-54HF switch supports shipping with fan trays and power supplies installed. For the switch to be shipped with fan trays or power supplies installed, contact the marketing staff.

CAUTION

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

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

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 2LAN Switching Configuration Guide.

CAUTION

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.

QSFP28 ports support the following transceiver modules and cables:

·     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.

·     40-GE QSFP+ transceiver modules in Table4-16.

LEDs

System status LED

The system status LED shows the operating status of the switch.

Table4-20 System status LED description

LED mark

Status

Description

SYS

Steady green

The switch is operating correctly.

Flashing green

The switch is performing power-on self test (POST).

Steady red

The system has failed POST, or a fault has occurred.

Flashing red

Some ports have failed POST.

Flashing blue (3 Hz)

Helps you to locate the device.

To locate the device, execute the locator blink command on the device. Then the SYS LED will be in this state.

Off

The switch is powered off or has failed to start up.

 

SFP28 port LED

Each SFP28 port has a status LED to show its operating status and activities.

Table4-21 SFP28 port LED description

LED status

Description

Steady green

A transceiver module or cable has been correctly installed. The port has a link and is operating at 25 Gbps.

Flashing green

The port is sending or receiving data at 25 Gbps.

Steady yellow

A transceiver module or cable has been correctly installed. The port has a link and is operating at 1 or 10 Gbps.

Flashing yellow (3 Hz)

The port is sending or receiving data at 1 or 10 Gbps.

Off

No transceiver module or cable has been installed or no link is present on the port.

Description

On

The fan tray is faulty.

Off

The fan tray is operating correctly.

 


5 Cooling system

CAUTION

CAUTION:

To guarantee heat dissipation, you must install fan trays of the same model for the switch.

 

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.
