AT-LXPWR Power Supply Module
The AT-LX3800U chassis is shipped with one AT-LXPWR power supply
preinstalled in slot A, and one empty slot (B) for an optional redundant
power supply (RPS). Two power supply versions, AC and DC, are
available for the AT-LX3800U chassis, as described below. Both slots
support any combination of AC and DC power supplies.
When two power supplies are installed, one of them works in standby
mode while the other one provides full power to the chassis. If one power
supply fails, the remaining power supply provides all the power to the
system, preventing a system failure.
