Power Supply

The 2028R-E1CR24L chassis has two redundant, hot-plug 920 Watt power sup-
plies. The power modules are hot-swappable, enabling them to be changed without
powering down the system.
These power supplies are auto-switching capable, allowing them to automatically
sense and operate at a 100v to 240v input voltage. An amber light will be illuminated
on the power supply when the power is off. An illuminated green light indicates that
the power supply is operating normally.
