AC Power Supply Tray
An optional AC power supply tray powers the MGX 8830 or MGX 8830/B switch from an AC power
source (100 to 120 or 200 to 240 VAC). The AC power supply tray houses one or two AC power supplies
and is installed directly below the switch. Each AC power supply module provides up to 1200 Watts of
–48 VDC power, which is sufficient to power a fully-loaded MGX 8830 or MGX 8830/B switch.
Figure1-35 Optional AC Power Supply
Two power supplies provide 1+1 redundancy. If no redundancy is desired, order an AC power supply tray
with one AC power supply module and one AC power cord.
Note Provide at least two inches of empty space around the front an d rear panels of the AC power supply for
cooling air flow.
Note For AC power cord requirements, see the “Required Tools and Equipment” section on page 3-53.
