The DIMM Standby Power LED will turn red when the system’s power is on or when it is in
the Suspend state (Power On Suspend or Suspend to RAM). It will not light when the system
is in the Soft-Off state. Lighted LED serves as a reminder that you must power-off the system
then turn off the power supply’s switch or unplug the power cord prior to installing any
memory modules.
For the Wake-On-KB and/or Wake-On-LAN function, the 5VSB power source of your power
supply must support ≥ 720mA.
For the Suspend to RAM function, the 5VSB power source of your power supply must
support ≥ 1A
For the Wake-On-USB KB function for 2 USB ports, the 5VSB power source of your power
supply must support ≥ 1.5A.
For the Wake-On-USB KB function for 3 or more USB ports, the 5VSB power source of
your power supply must support ≥ 2A.
