NOTE:
If a port uses a GPON optical module, other 10GE SFP+ optical ports cannot be used. |
4 | 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. |
| 5 | One console port | 6 | One USB port |
| 7 | Ground screw NOTE:
It is used with a ground cable. |
8 | RPS socket NOTE:
It is used with an RPS cable, which is not hot swappable. |
| 9 | Jack for AC power cable locking strap NOTE:
The AC power cable locking strap is not delivered
with the switch. |
10 | AC socket NOTE:
It is used with an AC power cable. |
Port Description
10/100/1000BASE-T portA 100M/1000M/2.5G BASE-T port (MultiGE port) sends and receives service data at 100 Mbit/s, 1 Gbit/s, or 2.5 Gbit/s, and must use an Ethernet cable. If the 2.5 Gbit/s speed is required, the port must use an Ethernet cable of Cat5e or higher category. Table 3 describes the attributes of a 100M/1000M/2.5G BASE-T 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 S5720-28X-PWH-LI-AC has the same types of indicators as the S5720-28X-PWR-LI-AC. For details, see Indicator Description.Power Supply Configuration
The S5720-28X-PWH-LI-AC has a built-in power module and does not support pluggable power modules. It is a PoE switch. In addition to the built-in PoE power module, the switch can also connect to an RPS1800 for power redundancy.
| Available PoE Power | Maximum Number of Ports (Fully Loaded) |
|---|---|
| 360 W |
|
Heat dissipation
The S5720-28X-PWH-LI-AC has two built-in fans for forced air cooling. Air flows in from the left side and front panel, and exhausts from the right side.

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 +50°C (23°F to 122°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. |
