Power System
The Switch 4800G 48-Port can adopt two hot-swappable AC or DC power
modules to provide backup.
■
AC power input
Rated voltage range: 100 VAC to 240 VAC, 50 Hz or 60 Hz
Input voltage range: 90 VAC to 264 VAC, 47 Hz to 63 Hz
■
DC power input
Rated voltage range: -48 VDC to -60 VDC
Input voltage range: -36 VDC to -72 VDC
Cooling System
The Switch 4800G 48-Port is equipped with six fans (four for the system, and one
for each power module) for heat dissipation.
