Each port has its own Port Activity LED. The Port Activity LED for a particular 
port is ON when Class 2, or 3 frames are entering or leaving the port. The Switch 
turns the LED ON for 50 msec. for each frame, so you should be able to see it for 
one frame. This LED will not light for frames following an arbitrated loop in 
bypass mode.

. The chassis contains two Input Power Assemblies, one for 

each power supply. The left assembly serves the left Power Supply. The right 
assembly serves the right Power Supply. Each assembly contains a connector for a 
standard 3-wire computer-type AC power cable (supplied with the Switch). The 
power cable connects between an AC Input Power Connector and an AC outlet. For 
purposes of redundancy, the AC outlets should be on separate circuits. Refer to 

 for the AC Power Requirements. See also

assembly. they each hold two input fuses. Refer to
