The RG-S5750-48GT/4SFP-S adopts the AC power input and redundant power input.
AC input:
Rated voltage range: 100–240 V AC
Maximum voltage range: 90–264 V AC
Frequency: 50/60 Hz
Rated current: 2 A
Power cable: 10 A power cable
HVDC input:
Voltage range: 192–290 V DC
Current range: 0.7–0.5 A
RPS input:
The switch power can be supplied by the redundant power input or both the AC input and redundant power input.
When both the AC input and the redundant power input are available, the switch power is supplied by the AC power
input.
When the AC input is unavailable, the switch power supply switches to the redundant power input seamlessly.
At present, the redundant power supply interface can be used together with the RPS150 that are
manufactured by Ruijie Networks. Unless otherwise stated, other power supply modules cannot be used for
power input; otherwise, an abnormality may occur or damage the switch.
Cooling System
The RG-S5750-48GT/4SFP-S adopts left and right fans for heat dissipation purposes, thereby ensuring the device's
functioning in the specified environment. Sufficient space (10 cm distance from both sides and the backplane of the
cabinet) should be reserved around the cabinet to allow air circulation. Dust the device every three months to avoid
blocking the ventilation openings.
