DXi4700 Expansion Module Power Supply Indicators
Each DXi4700 Expansion module power supply has LED indicators to show whether power is present or
whether a power fault has occurred (see Figure 28 below):
l DC Power - Lights green when the DC output voltage is within the limit.
l Power supply/cooling fan fault - Lights amber when a fault with the power supply or fan is detected.
l AC Power - Lights green when the AC output voltage is within the limit.
Caution: All power supplies are hot swappable. When replacing power supplies, never remove more
than one power supply at a time from the system. Also, before you remove one power supply, make
sure the other power supply is operating correctly (power indicator is green).
