Installing Line Card Motherboards and Transponder Modules

You can install up to eight hot-swappable line card motherboards in slots 2 to 5 and 8 to 11 of the Cisco ONS 15540 ESPx chassis.

Each line card motherboard holds up to four transponder modules that have a single protocol-transparent and bit-rate transparent external interface to the client side network and an internal interface that connects over the system's backplane to the mux/demux modules. The transponder modules are hot-pluggable, allowing in-service upgrades and replacement.

Transponders are available in single-mode and multimode. Line card motherboards are available with or without splitter protection.

Installing Line Card Motherboards

Perform the following procedure to install the line card motherboard:

Step 1 Remove the transponder side dust covers from the motherboard, and clean the optical connectors. See the “Cleaning Optical Connectors” section on page 2-28 .

Step 2 Insert the motherboard carefully into the chassis slot while guiding the upper and lower edges of the motherboard in the tracks until its connectors come into contact with the backplane.
