5.4.1 G1000-4 Card-Level Indicators

5.4.1 G1000-4 Card-Level Indicators

The G1000-4 card faceplate has two card-level LED indicators (Table 5-7).

Table 5-7 G1000-4 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 G1000-4 card. As part of the
	boot sequence, the FAIL LED turns on; it turns off if the software is deemed
	operational.
	The red FAIL LED normally blinks when the card is loading software.
ACT LED (green)	A green ACT LED provides the operational status of the G1000-4. If the
	ACT LED is green, it indicates that the G1000-4 card is active and the
	software is operational.

5.4.2 G1000-4 Port-Level Indicators

The G1000-4 card has one bicolor LED per port. Table 5-8describes the status that each color represents.

Table 5-8 G1000-4 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,
	an unconfigured circuit, an error on 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.

5.4.3 G1000-4 Compatibility

The G-Series card operates in Slots 1 to 6 and 12 to 17, for a total shelf capacity of 48 Gigabit Ethernet ports. The practical G1000-4 port per shelf limit is 40, because at least two slots are typically filled by OC-N trunk cards.

5.5 G1K-4 Card

The G1K-4 card is the functional equivalent of the G1000-4 card and provides four ports of IEEE-compliant, 1000-Mbps interfaces. Each interface supports full-duplex operation for a maximum bandwidth of 1 Gbps or 2 Gbps bidirectional per port, and 2.5 Gbps or 5 Gbps bidirectional per card. Each port autonegotiates for full duplex and IEEE 802.3x flow control. The G1K-4 card uses GBIC modular receptacles for the optical interfaces. For details, see the “5.8 GBICs and SFPs” section on page 5-14.
