Using LEDs to Check FSIP Status
Using LEDs to Check FSIP Status
The FSIP has several status LEDs on its faceplate, next to each port, which indicate conditions on
that port. (See Figure 22.)
Figure 22
After system initialization, the enabled LED goes on to indicate that the FSIP has been enabled for
operation.
The following conditions must be met before the FSIP is enabled:
•
•
•
If any one of these conditions is not met, or if the initialization fails, the enabled LED does not go on.
The four LEDs adjacent to each port indicate the state of that interface. The labels on each LED
indicate the signal state when the FSIP port is in DTE mode. When the FSIP port is in DCE mode,
the direction of the signals is reversed.
For example, a DCE device usually generates a clock signal, which it sends to the DTE device.
Therefore, when the FSIP port is a DTE port, the Receive Clock (RxC) LED indicates that the DTE
is receiving the clock signal from the remote DCE device. However, when the FSIP is operating as
a DCE, the RxC LED indicates that the DCE is sending a clock signal to the remote DTE device.
Only DTE mode states are labeled on each port because of limited space on the FSIP faceplate.
