EXP-INTF (Expansion Interface Circuit Pack)
Note:
fiber connected to the transmit side of the lightwave transceiver on one EI
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 fiber jumper cable, interconnect the transmit and receive jacks of the lightwave
transceiver as shown in Figure 65: 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.
Using cable lengths not within connectivity guidelines can adversely affect test
results.
4. Go to the front of the cabinet and inspect the amber LED.
● If the amber LED flashes on at a rate of once per second, the (EI or SNI) circuit pack or
transceiver should be replaced.
● If the amber LED flashes on at a rate of five times per second, the circuit pack (EI or SNI)
or the lightwave transceiver may need replacement. This condition may also be due to a
faulty system clock on the network containing this EI circuit pack.
● If the amber LED is not blinking, this circuit pack (EI or SNI) and the lightwave transceiver
are functioning properly.
5. Replace faulty components and reconnect the original fiber. Be sure to reconnect the fibers
properly as noted in step 3. If there is a problem with the PN after re-connecting the fiber,
and the PN is connected to a Center Stage Switch, run the Configuration Audit via test
board on the SNI circuit pack to which the intervening fiber is connected. See the SNI-BD
section for instructions on interpreting results.
6. Release EI circuit pack or SNI circuit pack with release board location.
