Connecting the NME Port
The NME (network management Ethernet) port uses a straight-through RJ-45
cable connector.
To connect cables to the NME port, follow these steps:
Step 1
Place the RJ-45 connector in front of the NME port on the processor card.
Step 2
Align the keyed ridge of the cable connector with the receiving slot on the
processor card connection point.
Step 3
Gently push the RJ-45 cable connector into the faceplate connection point until
the connector snaps into place.
Step 4
Route the fiber cables down through the cutout holes on the cable management
tray out of the right side of the shelf assembly.
Connecting Mux/Demux Modules
The Cisco ONS 15540 ESPx fiber optic mux/demux modules use MU connectors.
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 are shipped with the system that you
can use to do this.
The Cisco ONS 15540 ESPx supports mux/demux modules with front panel
optical filter connectors. Each mux/demux module supports a specific band of
channels. Every 4-channel band on the mux/demux module has its own MTP
connector. A 4-channel mux/demux module has one MTP connector, an 8-channel
has two, and a 32-channel mux/demux module has eight.
Caution
Follow all directions and warning labels when working with optical fibers. To
prevent eye damage, never look directly into a fiber or connector.
