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
Figure 1-7 :

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
Section 5 .
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.
