LED Function
SYS Indicates that the Ethernet controller is enabled for operation in the system. This LED
flashes while the RF switch is booting, and remains on during normal operation.
ERR Indicates that a serious error has occurred either while booting the RF switch, or
during line card operation.
ACT Indicates that there is activity over the 10BASE-T Ethernet RJ-45 interface. This LED
flashes as transmit/receive activity occurs.
LNK Indicates that the Ethernet port has established a valid link with the network.
TX This LED flashes as the Ethernet controller transmits data via the EIA/TIA-232
console port.
RX This LED flashes as the Ethernet controller receives data via the EIA/TIA-232
console port.
