Chapter 2 Quick Installation Procedures
Installing Cisco ONS 15540 ESPx Hardware
Installing Extended Range Transponder Modules
Perform this procedure to install extended range transponder modules.
Step 1 Remove the dust covers from the module, and clean the optical connectors. See the “Cleaning Optical
Connectors” section on page 2-28.
Step 2 Install the transceiver by inserting it into the extended range transponder. Push the transceiver until it is
securely set in the module.
Step 3 Lift the latch handle on the extended range transponder module and insert the module carefully into the
motherboard slot while guiding the upper and lower edges of the module in the tracks until its connectors
come into contact with the backplane connectors. You hear a click when it is connected.
Step 4 Push the latch on the module down to secure the module in place.
Table 2-10 lists the LEDs for the extended range transponder module.
Cabling Transponder Modules
To install fiber-optic cables in the Cisco ONS 15540 ESPx, a fiber cable with the corresponding
connector type must be connected to the transmit and receive ports on the modules. We recommend that
you label the transmit, receive and the working and protection fibers at each end of the fiber span to avoid
confusion with cables that are similar in appearance. Labels that you can use to do this are shipped with
the system.
To cable the transponder module client equipment, follow these steps:
Step 1 Place the cable connector in front of the connection point on the transponder module faceplate. Each
transponder module supports at least one transmit and one receive connector to create an optical carrier
port.
Step 2 Align the keyed ridge of the cable connector with the receiving slot on the faceplate connection point.
Step 3 Gently push the cable connector into the faceplate connection point until the connector snaps into place.
Step 4 Route the fiber cables down through the cable management tray out of the right side of the shelf
assembly.
