Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide, R3.3
May 2002
Chapter 3 Card Reference
E1000-2-G Card
The E1000-2-G Gigabit Ethernet card provides high-throughput, low-latency packet switching of
Ethernet encapsulated traffic (IP and other layer 3 protocols) across an SDH/SONET network while
providing a greater degree of reliability through SDH/SONET “self-healing” protection services. This
enables network operators to provide multiple 1000 MBits/s (Mbps) access drops for high-capacity
customer LAN interconnects, Internet traffic, and cable modem traffic aggregation. Efficient transport
and co-existence of traditional TDM traffic with packet-switched data traffic is provided.
The E1000-2-G card eliminates the need for external aggregation equipment such as Ethernet or ATM
switches at the customer site, remote headends or distributed POPs.
Each E1000-2-G card supports standards-based, layer 2 Ethernet switching between its Ethernet ports
and any other Ethernet or SDH/SONET trunk interfaces on the ONS 15454 SDH. The 802.1Q tag and
port-based VLANS logically isolate traffic (typically subscribers). Priority queuing is also supported to
provide multiple classes of service. Two queues are provided on card. Queue level is settable from 0 to
7; 0-3 and 4-7 map.
You can install the E1000-2-G card into any multispeed slot for a total shelf capacity of 20 Gigabit
Ethernet ports. Multiple Ethernet cards installed in an ONS 15454 SDH can act as either a single
switching entity or as a single switch supporting a variety of SDH/SONET port configurations.
You can create logical SDH/SONET ports by provisioning VC channels to the packet switch entity
within an ADM. Logical ports can be created with a bandwidth granularity of VC-4. In a single or
multicard configuration, the ONS 15454 SDH can support 1 VC-4-4c, 2 VC-4-2c, or 4 VC-4-1c
unstitched VC signal levels and 2 VC-4-2c, or 4 VC-4-1c stitched signal levels.
3.27.1 E1000-2-G Card-Level Indicators
The E1000-2-G card faceplate has two card-level LED indicators.
3.27.2 E1000-2-G Port-Level Indicators
The E1000-2-G card also has one bicolor LED per port. When the green LINK LED is on, the linkbeat
is detected, meaning an active network cable is installed. When the green LINK LED is off, an active
network cable is not plugged into the port. The amber port ACT LED flashes at a rate proportional to the
level of traffic being received and transmitted over the port.
Table 3-21 E1000-2-G Card-Level Indicators
Card-Level LEDs Description
Red FAIL LED The red FAIL LED indicates the card’s processor is not ready or catastrophic
software failure occurred on the E1000-2-G card. As part of the boot
sequence, the FAIL LED is turned on until the software deems the card
operational.
Green ACT LED A green ACT LED provides the operational status of the E1000-2-G. When
the ACT LED is green it indicates that the E1000-2-G card is active and the
software is operational.
