The NME (network management Ethernet) interface supports 10-Mbps or
100-Mbps UTP (unshielded twisted pair) ports. This RJ-45 interface supports
full-duplex or half-duplex connections.
The NME port on the processor card is a management port that allows multiple
simultaneous Telnet or SNMP network management sessions. The Ethernet port
on the processor card does not route or bridge traffic to other Ethernet ports on the
Cisco ONS 15540 ESPx. This Ethernet port is a management port only and cannot
be configured as a routing port.
Table 1-7
describes the LEDs used to confirm and troubleshoot the operation of
the NME interface. The LEDs on the processor faceplate indicate the status of the
NME interface.

The optical mux/demux motherboards occupy slots 0 and 1 of the
Cisco ONS 15540 ESPx chassis. The chassis uses one optical mux/demux
motherboard for unprotected operation or two per system for protected operation.
The chassis supports the following mux/demux motherboards:

•
•
Cisco ONS 15540 ESPx mux/demux motherboard without OSC
Each Cisco ONS 15540 ESPx mux/demux motherboard can accept up to four
4-channel or 8-channel mux/demux modules or one 32-channel mux/demux
module. The modular mux/demux motherboards are available with or without
OSC (optical supervisory channel) and can be populated according to user needs.
