By default, multi-GE ports support 100 Mbit/s, 1000 Mbit/s, 2.5 Gbit/s, 5 Gbit/s, and 10 Gbit/s.

There is a label on the rear side of the device, which contains the default rate "24*10GE" supported by the multi-GE ports.

A pre-configured or loaded RTU (right to use) license of a device is bound to the device ESN and cannot be unbound or transferred to other devices.

For details about the RTU licenses supported by the device and how to load them, see the License Usage Guide.

The rate of MultiGE ports can be increased using the RTU license. After the license is activated, you can run the assign group-speed command and restart the device to make the configured maximum rate supported by the ports in the MultiGE port group take effect. To check the default rate of MultiGE ports, run the display device group-speed configuration command. The BaseSpeed field indicates the default rate.

Port Description

100M/1000M/2.5GE/5GE/10GE BASE-T port (multi-GE port)

A 100M/1000M/2.5GE/5GE/10GE BASE-T port (multi-GE port) sends and receives service data at 100 Mbit/s, 1 Gbit/s, 2.5 Gbit/s, 5 Gbit/s, or 10 Gbit/s, and must use an Ethernet cable. If the 2.5 Gbit/s or 5 Gbit/s speed is required, the port must use an Ethernet cable of Cat5e or higher category. If the 10 Gbit/s speed is required, the port must use an Ethernet cable of Cat6A F/UTP or higher category. Table 4-1531 describes the attributes of a 100M/1000M/2.5GE/5GE/10GE BASE-T port.

6-a-1 stands for the six-around-one cable bundle mode, with one cable in the center and six cables bundled evenly around it.

If a port works at a rate of 5 Gbit/s, you are advised not to use unshielded Ethernet cables due to the following causes:
  • 802.3bz requires that the ALSNR value for alien crosstalk between Ethernet cables be greater than 0, but the standards for Cat5e and Cat6 unshielded twisted pairs do not specify the required ALSNR value. Therefore, such cables may not meet the crosstalk requirement in 802.3bz, causing severe problems such as continuous packet loss or port flapping may occur.
  • According the cabling specification TIA TSB-5021, using Cat5e and Cat6 cables for 5G poses high risks.
  • Currently, no clear onsite testing or evaluation method is available for checking whether ALSNR of cables conforms to 802.3bz.

If a port works at a rate of 5 Gbit/s and a Cat6 shielded Ethernet cable is used, the Ethernet cable must comply with ISO 11801 PL Class E (+All) or TIA Cat 6 Channel (+All). If a Cat6A shielded Ethernet cable is used, the Ethernet cable must comply with ISO 11801 PL2 Class Ea (+All) or TIA Cat6A Channel (+All). Otherwise, serious problems such as continuous packet loss or interface flapping may occur.

If a port works at a rate of 10 Gbit/s and a Cat6A shielded Ethernet cable is used, the Ethernet cable must comply with ISO 11801 PL2 Class Ea (+All) or TIA Cat6A Channel (+All). Otherwise, serious problems such as continuous packet loss or interface flapping may occur.

If Cat5e and Cat6 unshielded twisted pairs do not meet the 5G requirement, you are advised to replace them with shielded twisted pairs or reduce the rate of ports to 2.5G.

If Cat5E, Cat6, or Cat6A unshielded twisted pairs are used on electrical ports working at 10 Gbit/s, severe problems such as continuous packet loss or port flapping may occur.

10GE/25GE SFP28 optical port

A 10GE/25GE SFP28 optical port sends and receives service data at 10 Gbit/s, or 25 Gbit/s. Table 4-1533 describes the attributes of a 10GE/25GE SFP28 optical port.

In V200R012C00 and later versions, you can log in to the switch that contains the ETH management port for the first time through the ETH port. For details, see "First Login to a Switch" in the Configuration Guide - Basic Configuration. If you have logged in to the device for the first time by pressing and holding the MODE button for 6 seconds or longer and saved the configuration, the default configuration on the ETH port will be cleared. In this case, you cannot log in to the switch for the first time through the ETH port. You are advised to log in to the switch for the first time through the ETH port.

USB port

The USB port can have a USB flash drive connected to upgrade the switch, or transfer configuration files or other files. The USB port can only connect to a USB flash drive that complies with USB 2.0.

USB flash drives from different vendors differ in model compatibility and drivers. If a USB flash drive cannot be used, try to replace it with another one from a mainstream vendor. Switches support a maximum of 128 GB USB flash drives.

Indicator Description

Hold down the mode switch button for 6s and release it to start the web initial login mode. Either of the following situations will occur:
  • If the switch has no configuration file, the system attempts to enter the web initial login mode. In this mode, the status of mode indicators is as follows:
    • If the system enters the web initial login mode successfully, all mode indicators turn green and stay on for a maximum of 10 minutes.
    • If the system fails to enter the initial login mode, all mode indicators fast blink for 10 seconds and then restore the default status.
  • If the switch has a configuration file, the system cannot enter the web initial login mode. In this case, all mode indicators fast blink for 10s, and then return to the default states.

Typical power consumption (30% of traffic load, tested according to ATIS standard)

161 W (without card)

Operating temperature
-5°C to +45°C (23°F to 113°F) at an altitude of 0-1800 m (0-5906 ft.)
NOTE:

When the altitude is 1800-5000 m (5906-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).

The switch cannot be started when the ambient temperature is lower than 0°C (32°F).

The operating temperature of the switch is -5°C to 40°C (23°F to 104°F) when it uses QSFP-100G-ER4 optical module.

Storage temperature

-40°C to +70°C (-40°F to +158°F)

Noise under normal temperature (27°C, sound power)
