One 10/100/1000BASE-T port NOTE:
The port is an uplink port. The port can receive PoE power from a central switch through an Ethernet cable or the first-generation hybrid cable. |

Power Supply System
The remote unit supports the following power supply modes:
- Powered by an external power adapter (separately purchased)
- Powered by a central switch using an Ethernet cable of Cat5e or higher category (occupies the uplink electrical port, which is used for both PoE power input and data transmission)
- Powered by a central switch using the second-generation hybrid cable (occupies the uplink hybrid optical-electrical port, which is used for both PoE power input and data transmission)
- Powered by a central switch using the first-generation hybrid cable (occupies the uplink electrical port and uplink hybrid optical-electrical port. The uplink electrical port is used for PoE power input, and the uplink hybrid optical-electrical port is used for data transmission.)
When different power supply modes are used at the same time, the system preferentially uses the power adapter for power supply. The cold backup mode is used between different power supply modes and cannot supply power to the remote unit at the same time. The two uplink ports have no default priority, and the connection time is used as the priority.
The remote unit can provide PoE power for external PDs. The PoE power supply capability varies according to the power supply mode.

- |
Powered by a central switch |
Forcible power supply disabled (default): max 60 W |
|
|
Forcible power supply enabled: max 83 W |
|
When the remote unit is powered by the central switch, the total power consumption of the remote unit and its connected PDs cannot exceed 71.3 W. If the power consumption exceeds 71.3 W, the remote unit and its connected PDs will be powered off and restarted.
When the remote unit is powered by the central switch, the maximum available PoE power in the preceding table can be provided only when the following conditions are met:
- When forcible power supply is disabled by default:
- The PoE output of the central switch must comply with the 802.3bt class8 standard.
- When forcible power supply is enabled (using the poe force-power port command):
- The PoE output of the central switch must comply with the 802.3bt class8 standard.
- The central switch and the remote unit must be connected for a short distance (less than 8 m, with the line loss ignored). If the distance between the central switch and the remote unit is longer than 8 m and the PD is supplied with power based on the maximum power supply capability displayed on the central switch, the remote unit and the connected PD may be powered off and restarted.
- The output voltage of the power module used by the central switch cannot be lower than 55.5 V.
The actual available PoE power provided by the remote unit is calculated based on the cabling distance between the central switch and the remote unit, the cabling distance between the remote unit and the connected PD, the maximum power consumption of the remote unit, the PoE output voltage of the central switch, and PoE class level output by the central switch.
If the power output of the remote unit is manually configured to comply with 802.3at or 802.3af, the PD connected to the remote unit will be power-cycled when the remote unit is reset due to a cause other than power-off.
Heat Dissipation System
The remote unit has no fans and uses natural heat dissipation.
