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, 5 Gbit/s, or 10 Gbit/s speed is required, the port must use an Ethernet cable of Cat5e or higher category. Table 2 describes the attributes of a 100M/1000M/2.5GE/5GE/10GE BASE-T port.

Table 4 lists the maximum transmission distances of different cables on multi-GE ports.

**Table 4** Maximum transmission distances of different cables on multi-GE ports
Cable Type (6-a-1 Bundle)	Multi-GE Port (Different Rates)

Category 5e unshielded twisted pair (Cat5e UTP)	100 m	100 m	55 m 100 m (6-a-1 bundle only for the first 30 m) Not recommended due to high risk	Not supported

Category 7 twisted pair (Cat7)	100 m	100 m	100 m	100 m

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.

Some cables pose high risks and are not recommended for the following reasons:

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.
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 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.

1GE/10GE/25GE SFP28 optical port

A 1GE/10GE/25GE SFP28 optical port sends and receives service data at 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s. Table 5 describes the attributes of a 1GE/10GE/25GE SFP28 optical port.

**Table 5** Attributes of a 1GE/10GE/25GE SFP28 optical port
Attribute	Description
Connector Type	LC/PC
Optical port attributes	Depending on the optical module or cable in use
Standards compliance	IEEE802.3z, IEEE802.3ae, and IEEE802.3by
Working mode	When a 25GE optical module or cable is connected to a port, the port can automatically adjust its rate to 25 Gbit/s. When a 10GE optical module or cable is connected to a port, the port can automatically adjust its rate to 10 Gbit/s. Before installing a GE optical module or copper module on a port, run the port mode ge command to configure the port to work at 1 Gbit/s.

40GE/100GE QSFP28 optical port

A 40GE/100GE QSFP28 optical port sends and receives service traffic at 40 Gbit/s or 100 Gbit/s. Table 6 describes the attributes of a QSFP28 optical port.

**Table 6** Attributes of a QSFP28 optical port
Attribute	Description
Connector type	MPO/LC
Optical port attributes	Depend on the optical module used
Standards compliance	IEEE802.3ba

Console port

The console port is connected to a console for on-site configuration. The port must use a console cable. The console port is used when a switch is powered on for the first time. For details about the attributes of a console port, see Table 7.

**Table 7** Attributes of a console port
Attribute	Description
Connector type	RJ45
Standards compliance	RS-232
Working mode	Duplex Universal Asynchronous Receiver/Transmitter (UART)
Baud rate	9600 bit/s, 19200 bit/s, 38400 bit/s, 57600 bit/s, or 115200 bit/s Default value: 9600 bit/s

ETH management port

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. The port must use an Ethernet cable. 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. Table 8 describes the attributes of an ETH management port.

**Table 8** Attributes of an ETH management port
Attribute	Description
Connector type	RJ45
Standards compliance	IEEE802.3
Working mode	10/100 Mbit/s auto-sensing
Maximum transmission distance	100 m

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-H48UM2CC has the same types of indicators as the S5732-H24UM2CC. For details, see Indicator Description.

Power Supply Configuration

The S5732-H48UM2CC is a PoE switch. It has two power module slots, each of which can have a 1000 W PoE power module installed. Table 9 lists its power supply configurations.

**Table 9** Power supply configurations
Power Module 1	Power Module 2	Available PoE Power	Maximum Number of Ports (Fully Loaded)
1000 W (220 V)	–	621 W	802.3af (15.4 W per port): 40 802.3at (30 W per port): 20 802.3bt (60 W per port): 10

1000 W (220 V)	1000 W (220 V)	1571 W	802.3af (15.4 W per port): 48 802.3at (30 W per port): 48 802.3bt (60 W per port): 26
1000 W (110 V)	1000 W (110 V)	1381 W	802.3af (15.4 W per port): 48 802.3at (30 W per port): 46 802.3bt (60 W per port): 23

When a switch has two power modules installed, the two power modules work in redundancy mode to provide power for the chassis and in load balancing mode to provide power for PDs.

Figure 2 shows the power supply mode of dual AC PoE power modules (PWR1 and PWR2). After AC power is transmitted to the PWR modules, the PWR modules provide 56 V outputs. The outputs are combined on the motherboard, which then provides 12 V voltage for the switch and 56 V voltage for the PDs.

N: neutral wire

PGND: protection ground wire

GND: 12 V reference ground

Heat Dissipation

The S5732-H48UM2CC uses pluggable fan modules for forced air cooling. Air flows in from the left, right, and front sides, and exhausts from the rear panel.
