Version Mapping
Table 1 lists the mapping between the S5720I-28X-SI-AC chassis and software versions.
Appearance and Structure
| 1 | AC power input port 1 NOTE:
It must be used with the Phoenix connector, which is included in the installation accessory package. |
2 | AC power input port 2 NOTE:
It must be used with the Phoenix connector, which is included in the installation accessory package. |
| 3 | One console port | 4 | One PNP button NOTICE:
To restore the factory settings and reset the switch, hold down the button for at least 6 seconds. To reset the switch, press the button. Resetting the switch will cause service interruption. Exercise caution when you press the PNP button. |
| 5 | One USB port | 6 | Twenty-four 10/100/1000BASE-T ports |
| 7 | Four 10GE SFP+ ports | 8 | Monitoring port NOTE:
It must be used with the Phoenix connector, which is included in the installation accessory package. The monitoring port detects the status of external devices, for example, monitoring the opening and closing of the cabinet door. For details about how to use a monitoring port, see "Monitoring Interface Configuration" in the CLI-based Configuration Guide - Device Management Configuration Guide. |
| 9 | Ground screw NOTE:
It is used with a ground cable. |

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 S5720I-28X-SI-AC has similar indicators to those of the S5720I-28X-PWH-SI-AC except that the S5720I-28X-SI-AC does not have a PoE mode indicator. For details, see Indicator Description.Power Supply Configuration
The S5720I-28X-SI-AC has two built-in power modules for 1+1 power redundancy and does not support pluggable power modules.
Heat Dissipation
The S5720I-28X-SI-AC has two built-in fans for forced air cooling. The airflow direction is left-to-right.
