5.6.4 Slot Compatibility
The G1000-4 card requires Cisco ONS 15454 Release 3.2 or later system software and the XC10G
cross-connect card. You can install the card 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 such as the OC-192.
5.7 G1K-4 Card
Note For hardware specifications, see the “A.7.7 G1K-4 Card Specifications” section on page A-47.
The G1K-4 card is the functional equivalent of the earlier 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 “5.13 Ethernet Card GBICs and SFPs”
section on page 5-31.
Figure 5-6 shows the card faceplate and the block diagram of the card.
Table 5-12 G1000-4 Port-Level Indicators
Port-Level LED Status 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.
