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.
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.
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.
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.
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
The S6720-54C-EI-48S-AC has the same types of indicators as the S6720-30C-EI-24S-AC. For details, see Indicator Description.
Power Supply Configuration
The S6720-54C-EI-48S-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 2 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.
Heat Dissipation
The S6720-54C-EI-48S-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.
Technical Specifications
Table 6 lists technical specifications of the S6720-54C-EI-48S-AC.
