S5720S-28X-LI-AC
Version Mapping
Table 1 lists the mapping between the S5720S-28X-LI-AC chassis and software versions.
Appearance and Structure
| 1 | Twenty-four 10/100/1000BASE-T ports | 2 | Four 10GE SFP+ ports Applicable modules and cables:
NOTE:
A switch can use a maximum of two 10GE optical modules with 40 km or longer transmission distances. If a port uses a GPON optical module, other 10GE SFP+ optical ports cannot be used. |
| 3 | One PNP button NOTICE:
Applicable in V200R012C00 and later versions: 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. |
4 | One console port |
| 5 | Ground screw NOTE:
It is used with a ground cable. |
6 | Jack for AC power cable locking strap NOTE:
The AC power cable locking strap is not delivered
with the switch. |
| 7 | AC socket NOTE:
It is used with an AC power cable. |

Port Description
10/100/1000BASE-T portIndicator Description
The S5720S-28X-LI-AC has similar indicators to those of the S5720-28X-PWR-LI-AC except that the S5720S-28X-LI-AC does not have an RPS, USB, or PoE mode indicator. For details, see Indicator Description.Power Supply Configuration
The S5720S-28X-LI-AC has a built-in power module and does not support pluggable power modules.
Heat Dissipation
The S5720S-28X-LI-AC has a built-in fan for forced air cooling. Air flows in from the left side and front panel, and exhausts from the right side.

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) |
< 47 dB(A) |
