Port Description

10GE SFP+ 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 2 describes the attributes of a 10GE SFP+ Ethernet optical port.

Table 2 Attributes of a 10GE SFP+ port

Attribute	Description
Connector type	LC/PC
Optical port attributes	Depend on the optical module used
Standards compliance	IEEE802.3ae
Working mode	GE/10GE auto-sensing

40GE QSFP+ port

A 40GE QSFP+ optical port sends and receives service traffic at 40 Gbit/s and can be split into four 10GE ports. After a split, 40GE QSFP+ optical port needs to be connected to a remote device using a 1-to-4 QSFP+ fiber (with matching optical modules), 1-to-4 QSFP+ AOC cable, or a 1-to-4 QSFP+ copper cable. Table 3 describes the attributes of a 40GE QSFP+ optical port.

Table 3 Attributes of a 40GE QSFP+ 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 4.

Table 4 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. For details on how to use the ETH management port, see the Configuration Guide - Basic Configurations. Table 5 describes the attributes of an ETH management port.

Table 5 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

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.

 NOTE:

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

 NOTE:

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 to 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.

Figure 2 Indicators on the S6720-30C-EI-24S-AC

 NOTE:

The S6720-EI series switches provide a command for setting fault indicators, which help field maintenance personnel find a faulty switch quickly.

The SYS indicator and mode indicators (STAT, SPED, and STCK) are used as fault indicators. When an S6720-EI switch is faulty, you can run the command to turn on the fault indicators. Then the SYS indicator and mode indicators fast blink red to help field maintenance personnel quickly find the faulty switch.

Power Supply Configuration

The S6720-30C-EI-24S-AC can be configured with a single power module or double power modules for 1+1 power redundancy. AC and DC power modules can be used together in the same switch.

Figure 3 shows the power supply connections of dual DC power modules. After DC power is transmitted to the PWR module, the PWR module provides 12 V output voltage, and the motherboard provides power for the entire device.

Figure 3 Power supply connections of dual DC power modules

NEG: negative cable

RTN: positive cable

GND: 12 V reference ground

Figure 4 shows the power supply connections of dual non-PoE AC power modules. After AC power is transmitted to the PWR module, the PWR module provides 12 V output voltage, and the motherboard provides power for the entire device.

L: Live wire

N: Neutral wire

PGND: Protective ground cable

GND: 12 V reference ground

Heat Dissipation

The S6720-30C-EI-24S-AC uses pluggable fan modules for forced air cooling. Air flows in from the left side, right side, and front panel, and exhausts from the rear panel.

 NOTE:

This figure only shows the airflow direction and does not depict the actual device.
