Port Description
10/100/1000BASE-T port
10GE SFP+ port
Console port
USB port
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 S5720-52X-LI-AC has similar indicators to those of the S5720-28X-PWR-LI-AC, except that the S5720-52X-LI-AC does not have a PoE mode indicator. For details, see Indicator Description.
Power Supply Configuration
The S5720-52X-LI-AC has a built-in power module and does not support pluggable power modules. It can connect to an RPS1800 power supply for power redundancy.
Heat Dissipation
The S5720-52X-LI-AC has a built-in fan for forced air cooling. The airflow direction is left-to-right.
This figure only shows the airflow direction and does not depict the actual device.

Operating temperature |
0°C to 45°C (32°F to 113°F) at an altitude of 0-1800 m (0-5906 ft.)
NOTE:
When the altitude is 1800-5000 m (5906-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.). |
Short-term operating temperature |
-5°C to +55°C (23°F to 131°F) at an altitude of 0-1800 m (0-5906 ft.) NOTE:
When the altitude is 1800-5000 m (5906-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.). The equipment can operate beyond the normal operating temperature range for a short-term period, but the following conditions must be met:
The equipment cannot start when the temperature is lower than 0°C (32°F). The maximum distance of optical modules used in these conditions cannot exceed 10 km. |
Storage temperature |
-40°C to +70°C (-40°F to +158°F) |
Noise under normal temperature (27°C, sound power) |
< 44.5 dB(A) |
