Chapter 5 Ethernet Cards
5.11.1 ML-MR-10 Card-Level Indicators
The ML-MR-10 card supports an Ethernet Virtual Connection (EVC), which is an instance of an
association of two or more user network interfaces (UNI) for Ethernet services. For more information
on EVC, refer to the Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card Software Feature and
Configuration Guide.
5.11.1 ML-MR-10 Card-Level Indicators
The ML-MR-10 card faceplate has two card-level LED indicators, described in Table 5-25.
5.11.2 ML-MR-10 Port-Level Indicators
The ML-MR-10 card provides a pair of LEDs for each Ethernet port: an amber LED for activity (ACT)
and a green LED for link status (LINK). Table 5-26 describes the status that each color represents.
5.11.3 Cross-Connect and Slot Compatibility
The ML-MR-10 card can be installed in Slots 1 to 6 and 12 to 17 when used with the XC10G and
XC-VXC-10G cards. It is not compatible with the XCVT card.
Caution Fan-tray assembly 15454-CC-FTA (ANSI shelf) must be installed in a shelf where an ML-MR-10 card
is installed.
Table 5-21 ML-MR-10 Card-Level Indicators
Card-Level LEDs Description
FAIL LED (Red) The red FAIL LED indicates that the card processor is not ready or that a
catastrophic software failure occurred on the ML-MR-10 card. As part of the
boot sequence, the FAIL LED is turned on until the software deems the card
operational.
ACT LED (Green) The green ACT LED provides the operational status of the ML-MR-10 card.
When the ACT LED is green, it indicates that the ML-MR-10 card is active
and the software is operational.
Table 5-22 ML-MR-10 Port-Level Indicators
Port-Level Indicators Description
Off No link exists to the Ethernet port.
Steady amber A link exists to the Ethernet port, but traffic flow is inhibited. For
example, a lack of circuit setup, an error on the line, or a disabled port
might inhibit traffic flow.
Solid green A link exists to the Ethernet port, but no traffic is carried on the port.
Flashing green A link exists to the Ethernet port, and traffic is carried on the port. The
LED flash rate reflects the traffic rate for that port.
