Port Description
10/100/1000BASE-T port
A 10/100/1000BASE-T Ethernet electrical port sends and receives service data at 10/100/1000 Mbit/s, and must use an Ethernet cable. Table 4-1141 describes the attributes of a 10/100/1000BASE-T Ethernet electrical port.
Table 4-1141 Attributes of a 10/100/1000BASE-T Ethernet electrical port
| Attribute | Description |
|---|---|
| Connector type | RJ45 |
| Standards compliance | IEEE802.3, IEEE802.3u, IEEE802.3ab |
| Working mode | 10/100/1000 Mbit/s auto-sensing |
| Maximum transmission distance | 100 m |
1000BASE-X port
When a 1000BASE-X port uses a GE optical module, it can only transmit and receive data at 1000 Mbit/s and does not support the 100 Mbit/s transmission speed. When a 1000BASE-X port uses a FE optical module, it can transmit and receive data at 100 Mbit/s. When a 1000BASE-X port uses a GE copper module, it can transmit and receive data at 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s. Table 4-1142 describes the attributes of a 1000BASE-X Ethernet optical port.
Table 4-1142 Attributes of a 1000BASE-X Ethernet optical port
| Attribute | Description |
|---|---|
| Connector type | LC/PC |
| Optical port attributes | Depend on the module used |
| Standards compliance | IEEE802.3z |
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 4-1143.
Table 4-1143 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/sDefault 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 4-1144 describes the attributes of an ETH management port.
Table 4-1144 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 mIn 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 switch 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 S5735-L24T4S-A has similar indicators to those on the S5735-L12P4S-A except that the S5735-L24T4S-A does not have a PoE mode indicator. For details, see Indicator Description.
Power Supply Configuration
The S5735-L24T4S-A has a built-in AC power module and does not support pluggable power modules.
Heat Dissipation
The S5735-L24T4S-A has no fans and uses natural heat dissipation.
