SNI-BD (SNI Circuit Pack)
Note:
which is the transmit fiber and which is the receive fiber for proper
re-connection at the end of this procedure. The fiber connected to the transmit
side of the lightwave transceiver on one circuit pack should be connected to the
receive side of the lightwave transceiver on the circuit pack on the opposite end
of the fiber.
3. Using a spare fiber jumper cable, interconnect the transmit and receive jacks of the
lightwave transceiver as shown in Figure 107: Interconnection of Lightwave Transceiver
Transmit/Receive Jacks.
Note:
sure that the total length of the fiber jumper cable does not exceed the
maximum length recommended for the fiber link connections between cabinets.
Test the Expansion Interface or SNI circuit pack within connectivity guidelines so
that test results are not influenced due to improper cable length.
4. Go to the front of the cabinet and inspect the yellow LED.
● If the yellow LED flashes on at a rate of once per second, the Expansion Interface or
Switch Node Interface circuit pack or transceiver should be replaced.
● If the yellow LED flashes on at a rate of five times per second, the circuit pack
(Expansion Interface or Switch Node Interface) or the lightwave transceiver may need
replacement. This may also be due to a faulty system clock on the network containing
the Expansion Interface circuit pack or in the switch node carrier containing the SNI.
● If the yellow LED was blinking before starting this procedure and the yellow LED is not
blinking now, this circuit pack (Expansion Interface or Switch Node Interface) and the
lightwave transceiver are functioning properly.
5. Replace faulty component(s) and reconnect the original fiber. Be sure to reconnect the
fibers properly as noted in Step 2.
6. Use release board location to release the Expansion Interface circuit pack or
Switch Node Interface circuit pack.
