1.8.3. QSW-M-4700-POE-AC Module
The QSW-4700-28TX-POE and QSW-4700-52TX-POE switches support the QSW-M-4700-
POE-AC power module. The QSW-M-4700-POE-AC is an AC module (AC/HVDC input and DC
output) providing an output voltage of 56 V and an output power of up to 600 W (PoE power:
370 W).
Note:
•
The switch can be powered on by either one power supply module or dual power supply
modules. If both power supply modules are used, the switch works in the power
redundancy mode. The switch supports 1+1 power redundancy when the PoE power
consumption is less than 370 W.
•
At least one power supply module is required. If any slot is unoccupied, install a filler
panel to enable proper airflow.
