Chapter 2 Quick Installation Procedures
Installing Cisco ONS 15540 ESP Hardware
Installing 4-Channel or 8-Channel Mux/Demux Modules
This section describes the procedure for installing a 4-channel or 8-channel mux/demux module in the
Cisco ONS 15540 ESP. To install the module, follow these steps:
Step 1 Remove the dust covers from the module, and clean the optical connectors. See the “Cleaning Optical
Connectors” section on page 2-28.
Caution Wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the
backplane with your hand or any metal tool, or you could shock yourself.
Step 2 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.
Table 2-2 lists the LEDs on the mux/demux motherboard with OSC faceplate, their default conditions,
and what the conditions indicate.
Installing 16-Channel Mux/Demux Modules
This section describes the procedure for installing 16-channel mux/demux modules in the
Cisco ONS 15540 ESP. To install the 16-channel mux/demux module, follow these steps:
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 Insert the correct inset tray for the 16-channel mux/demux module and secure the tray to the
motherboard by tightening the screws.
Step 3 Insert the 16-channel mux/demux module with OSC carefully into the top 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 If you are installing a second 16-channel mux/demux module, insert the module without OSC carefully
into the bottom 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.
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 ESP 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.
