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.
- 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.
| Port | Connector Type | Description | Available Components |

| 100M/1000M/2.5GE BASE-T PoE++ port (multi-GE port) | RJ45 | A 100M/1000M/2.5GE BASE-T port (multi-GE port) sends and receives service data at 100 Mbit/s, 1 Gbit/s, 2.5 Gbit/s. The port supports the PoE function. |
If the 2.5 Gbit/s speed is required, the port must use an Ethernet cable of Cat5e or higher category. |
| 100M/1000M/2.5GE/5GE/10GE BASE-T PoE++ port (multi-GE port) | RJ45 | 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. The port supports the PoE function. |
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. |
| 10GE SFP+ optical port | SFP+ | A 10GE SFP+ Ethernet optical port supports auto-sensing to 1000 Mbit/s. It sends and receives service data at 1000 Mbit/s or 10 Gbit/s. |
|
| 40GE SFP+ optical port | QSFP+ | A 40GE QSFP+ optical port sends and receives service traffic at 40 Gbit/s. A 40GE QSFP+ optical port can be split into four 10GE ports. |
|
| Console port | RJ45 | The console port is connected to a console for on-site configuration. | |
| ETH management port | RJ45 | You can connect a switch to a configuration terminal or network management workstation through the ETH management port to configure the switch locally or remotely. You can choose to download the software package through the ETH management port in the BootLoad menu. File transfer through the ETH management port is faster than transfer through the console port. |
|
| USB port | USB 2.0 Type A | 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. |

Indicators and Buttons
The S5731-S8UM16UN2Q has the same types of indicators as the S5731-S24UN4X2Q. For details, see the S5731-S24UN4X2Q.
Power Supply System
The switch is a PoE switch and supports three power module slots, each of which can have a 1000 W PoE or 600 W PoE power module installed. Pluggable AC and DC PoE power modules can be used together in the same switch.

When a switch has multiple power modules installed, the multiple power modules work in redundancy mode to provide power for the chassis and in load balancing mode to provide power for PDs.
Heat Dissipation System
The switch has two built-in fans for forced air cooling. Air flows in from the left and front sides, and exhausts from the rear panel.
This figure only shows the airflow direction and does not depict the actual device.
