5.5.2 G1K-4 Card-Level Indicators
5.5.2 G1K-4 Card-Level Indicators
The G1K-4 card faceplate has two card-level LED indicators, described in Table 5-9.
5.5.3 G1K-4 Port-Level Indicators
The G1K-4 card has four bicolor LEDs (one LED per port). Table 5-10 describes these LEDs.
5.6 ML100T-12 Card
The ML100T-12 card provides 12 ports of IEEE 802.3-compliant, 10/100 interfaces. Each interface
supports full-duplex operation for a maximum bandwidth of 200 Mbps per port and 2.488 Gbps per card.
Each port independently detects the speed of an attached device (autosenses) and automatically connects
at the appropriate speed. The ports autoconfigure to operate at either half or full duplex and can
determine whether to enable or disable flow control. For ML-Series configuration information, see the
Cisco ONS 15454 SONET/SDH ML-Series Multilayer Ethernet Card Software Feature and
Configuration Guide.
Figure 5-5 shows the card faceplate.
Caution Shielded twisted-pair cabling should be used for inter-building applications.
Table 5-9 G1K-4 Card-Level Indicators
Card-Level LEDs Description
FAIL LED (red) The red FAIL LED indicates that the card’s processor is not ready or that a
catastrophic software failure occurred on the G1K-4 card. As part of the boot
sequence, the FAIL LED is turned on, and it goes off when the software is
deemed operational.
The red FAIL LED blinks when the card is loading software.
ACT LED (green) A green ACT LED provides the operational status of the G1K-4. If the ACT
LED is green, it indicates that the G1K-4 card is active and the software is
operational.

Port-Level LED State 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 nonenabled 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 the port.
