CR-SEB
Status Indicators
The PWR indicator on the front panel indicates that power is applied to the CR-SEBX. The CR-SEBX
does not have a power switch. Power is applied and removed to the CR-SEBX by connecting and
disconnecting the power connector.
The Ethernet LEDs include LINK, TXD and RXD. The LINK LED lights when a valid Ethernet
connection is made. The CR-SEB is set up to use a straight through cable to connect to a PC. If a straight
through cable is used to connect the CR-SEB to other devices through a hub, the CR-SEB must be
connected to the uplink port on the hub. TXD and RXD are indicators of Ethernet data activity. They
indicate the transmission and reception of data over the Ethernet connection. Note that these LEDs can be
active even when the CR-SEB is not communicating with another CR-SEB.
The RF indicators include LINK and XCVR. On a slave CR-SEB, the RF Link LED indicates
the CR-SEB has established a connection with the master CR-SEB. When a slave CR-SEB is
powered on, it will take a few seconds for this LED to turn on. On a master CR-SEB the RF Link
LED is on as long as any one Slave is linked. The XCVR OK LED on the CR-SEBX when on
indicates the remote radio of the CR-SEBX is operating properly.
