The four activity LEDs on the front panel of the KVM/netPlus light at boot time to indicate the number of KVM over IP (KVM/IP) modules installed on the unit and blinks to indicate the number of IP users simultaneously logged into the WMI.The number of IP modules installed indicates the number of IP users that are able to access the WMI at one time. The KVM/netPlus is furnished with up to four KVM/IP modules installed; however, the actual number of IP modules depends on the model ordered.Note: If a KVM/netPlus is furnished with fewer than four IP modules, one or more of the LEDs does not light.
