LEDs
The PA-POS-2OC3 faceplate has five LEDs that indicate port adapter and interface status. (See
Figure 1-2
PA-POS-2OC-3 LEDs
lists the LEDs colors, status, and function.
After system initialization, the ENABLED LED comes on to indicate that power is received and that the
PA-POS-2OC3 is enabled for operation.
The following conditions must all be met before the PA-POS-2OC3 is enabled:
•
The PA-POS-2OC3 is correctly connected and receiving power.
•
The host system software supports the PA-POS-2OC3.
If any one of these conditions is not met, or if the initialization fails, the ENABLED LED does not come
on.
Cables and Connectors
Use single-mode (for intermediate- or long-reach configurations) or multimode optical fiber cable to
connect your router to a network or to connect two OC-3-equipped routers back to back.
Note
Long-range SFP optics modules (for long-reach configurations) cannot be connected
back-to-back without using an attenuator between the two of them.
