1.8.2. QSW-M-4700-DC Module
The QSW-4700-28TX, QSW-4700-52TX, QSW-4700-28F and QSW-4700-52F switches support
the QSW-M-4700-DC power module. The QSW-M-4700-DC is a DC module (DC input and DC
output) providing an output voltage of 12 V and an output power of up to 150 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.
•
At least one power supply module is required. If any slot is unoccupied, install a filler
panel to enable proper airflow.
