Power Supplies and Fans
The model 5800V switch is equipped with a single, non-replaceable power supply. 
The model 5802V switch is equipped with dual, replaceable power supplies.
Model 5800V
The model 5800V switch has a single power supply that converts 100–240 VAC to 
DC voltages for the various switch circuits. Internal fans provide cooling. The 
switch monitors internal air temperature, and therefore does not monitor or report 
fan operational status. Air flow is front-to-back. To energize the switch, plug the 
power cord into the switch AC receptacle and into a 100–240 VAC power source.
Model 5802V
The model 5802V switch has two, hot-pluggable power supplies that convert 
100–240 VAC to DC voltages for the various switch circuits. Each power supply 
has an AC power receptacle and two status LEDs as shown in 
:
The Power Supply Fault LED (amber) lights up to indicate that a power 
supply fault exists and requires attention.
The Power Supply Status LED (green) lights up to indicate that the power 
supply is receiving AC voltage and producing the correct DC voltages.
Figure 1-7. Model 5802V Power Supplies
Each power supply can supply all of the switch’s power needs. During normal 
operation, each power supply provides half of the demand. If one power supply 
goes offline, the second power supply steps up and provides the difference.
The power supplies are hot-pluggable and interchangeable. Hot-pluggable means 
that you can remove and replace one power supply while the switch is in 
operation without disrupting service. For information about replacing power 
supplies, refer to 
.
Connecting a power supply to an AC voltage source energizes the switch logic 
circuitry. Internal fans provide cooling. Air flow can be front-to-back or 
back-to-front.
