Power Supply/Fan Module LED
The switch uses two power supply/fan modules to guarantee high availability with failover. Each power
supply has a separate LED to indicate its condition.
When a power supply or fan fault occurs, the switch will continue to operate normally as long as the
faulty power supply/fan module remains installed in the switch and there are at least two fans
operational in each module. If the power supply/fan module is removed from the switch, the switch will
continue to operate normally for approximately 20-30 minutes. However, to guarantee continued
operation, the malfunctioning module should be immediately replaced to maintain high availability.
