Twenty-four PoE++ 100M/1000M/2.5GE/5GE/10GE BASE-T ports (multi-GE ports)

NOTE:

The S5732-H48XUM2CC is a hybrid optical-electrical switch. You can use one multi-GE port and one 10GE SFP+ optical port together by connecting them through a hybrid cable. This cable is composed of copper cores terminated on RJ45 connectors and optical fibers terminated on LC connectors. The typical application scenario is as follows:

  • The copper cores connect a multi-GE port of a switch to a PoE_IN port of an AP to allow the switch to supply power to the AP while no data is transmitted over this cable.

  • The optical fibers connect a SFP+ optical port on the switch to a SFP+ optical port of the AP to transmit data.

Twenty-four 10GE SFP+ ports

NOTE:

It is recommended that optical fibers in the first-generation hybrid cables be fusion spliced onsite. If you assemble optical fibers in hybrid cables in mechanical splicing mode, only SFP-10G-iLR-S optical modules are supported.

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 4-1562 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.

The PoE power supply capability and distance of multi-GE ports on the S5732-H48XUM2CC vary depending on the power supply medium, as listed in Table 4-1564.

An AP can receive a maximum of 57 W power from a multi-GE port within the power supply distance of 100 m.

When a common Cat6A shielded cable is used for both PoE power supply and data transmission (10 Gbit/s), the maximum power supply distance is 100 m in compliance with 802.3bt.

When a common Cat5E, Cat6, or Cat6A Ethernet cable is used only for PoE power supply and optical fibers are used for data transmission, the maximum power supply distance is 150 m in compliance with 802.3bt.

A hybrid cable supplies PoE power to specific AP models through its copper cores and transmits data through its optical fibers. For details about the AP models to which hybrid cables can supply power, see the WLAN AP product documentation.

A hybrid cable cannot be used to supply power to dual-signature APs.

A hybrid cable can offer the power supply capabilities listed in Table 4-1564 only when the impedance of its copper cores is within 12.8 ohms/km. If the impedance exceeds this value, the power supply capabilities (power received by and voltage of the AP) will decrease.

10GE SFP+ optical port

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. Table 4-1565 describes the attributes of a 10GE SFP+ Ethernet 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

The S5732-H48XUM2CC has the same types of indicators as the S5732-H24UM2CC. For details, see Indicator Description.

Power Supply Configuration

The switch is a PoE switch and supports two 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.
