5.5.2 G1K-4 Card-Level Indicators

The G1K-4 card faceplate has two card-level LED indicators, described in Table 5-9.

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.

 

 

5.5.3 G1K-4 Port-Level Indicators

The G1K-4 card has four bicolor LEDs (one LED per port). Table 5-10describes these LEDs.

Table 5-10 G1K-4 Port-Level Indicators

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.

 

 

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 5-5shows the card faceplate.

Caution Shielded twisted-pair cabling should be used for inter-building applications.
