Ethernet Cards

Note The terms “Unidirectional Path Switched Ring” and “UPSR” may appear in Cisco literature. These terms

do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as “Path Protected Mesh Network” and “PPMN,” refer generally to Cisco’s path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

The Cisco ONS 15454 SDH integrates Ethernet into a SDH time-division multiplexing (TDM) platform. This chapter describes the Cisco ONS 15454 SDH E-Series Ethernet cards, G-Series Ethernet cards, and ML-Series Ethernet cards. It includes descriptions, hardware specifications, and block diagrams for each card. For G-Series and E-Series Ethernet application information, see Chapter 14, “Ethernet Operation.” For installation and card turn-up procedures, refer to the Cisco ONS 15454 SDH Procedure Guide. For ML-Series configuration information, see the Ethernet Card Software Feature and Configuration Guide.

5.1 Ethernet Card Overview

The card overview section summarizes card functions, power consumption, and temperature ranges.

Note Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 SDH shelf

assembly. The cards are then installed into slots displaying the same symbols. See the Cisco ONS 15454 SDH Procedures Guide for a list of slots and symbols.

5.2 E100T-G Card

The ONS 15454 SDH uses E100T-G cards for Ethernet (10 Mbps) and Fast Ethernet (100 Mbps). Each card provides 12 switched, IEEE 802.3-compliant, 10/100BaseT Ethernet ports that can independently detect the speed of an attached device (autosense) and automatically connect at the appropriate speed.

The ports autoconfigure to operate at either half or full duplex and determine whether to enable or disable flow control. You can also configure Ethernet ports manually. Figure 5-1 shows the faceplate and a block diagram of the card.

The E100T-G Ethernet card provides high-throughput, low-latency packet switching of Ethernet traffic across a SDH network while providing a greater degree of reliability through SDH self-healing protection services. This Ethernet capability enables network operators to provide multiple 10/100-Mbps access drops for high-capacity customer LAN interconnects, Internet traffic, and cable modem traffic aggregation. It enables the efficient transport and co-existence of traditional TDM traffic with packet-switched data traffic.

April 2008

Each E100T-G card supports standards-based, wire-speed, Layer 2 Ethernet switching between its Ethernet interfaces. The IEEE 802.1Q tag logically isolates traffic (typically subscribers). IEEE 802.1Q also supports multiple classes of service.

5.2.1 E100T-G Slot Compatibility

You can install the E100T-G card in Slots 1 to 6 and 12 to 17. Multiple E-Series Ethernet cards installed in an ONS 15454 SDH can act independently or as a single Ethernet switch. You can create logical SDH ports by provisioning a number of SDH channels to the packet switch entity within the ONS 15454 SDH. Logical ports can be created with a bandwidth granularity of VC-4.

5.2.2 E100T-G Card-Level Indicators

The E100T-G card faceplate has three card-level LED indicators (Tabl e 5-3 ).

Ta b l e 5 - 3 E 10 0 T- G C a r d - L e v e l Indica to r s

Card-Level Indicators Description

Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready or that a

catastrophic software failure occurred on the E100T-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 E100T-G. If the

ACT LED is green, it indicates that the E100T-G card is active and the software is operational.

SF LED Not used.

Chapter 5 Ethernet Cards

5.2.3 E100T-G Port-Level Indicators

The E100T-G card also has 12 pairs of LEDs (one pair for each port) to indicate port conditions (Tabl e 5-4 ). You can find the status of the E100T-G card port using the LCD screen on the ONS 15454 SDH fan-tray assembly. Use the LCD to view the status of any port or card slot; the screen displays the number and severity of alarms for a given port or slot.

Table 5-4 E100T-G Port-Level Indicators

LED State Description

Amber Port is active (transmitting and/or receiving data). By default, indicates the

transmitter is active but can be software controlled to indicate link status, duplex status, or receiver active.

Solid Green Link is established. By default, indicates the link for this port is up, but can

be software controlled to indicate duplex status, operating speed, or collision.

5.3 E1000-2-G Card

The ONS 15454 SDH uses E1000-2-G cards for Gigabit Ethernet (1000 Mbps). The E1000-2-G card provides two IEEE-compliant, 1000-Mbps ports for high-capacity customer LAN interconnections. Each port supports full-duplex operation.

5.3.1 E1000-2-G Compatibility

Each E1000-2-G card supports standards-based, Layer 2 Ethernet switching between its Ethernet interfaces and SDH interfaces on the ONS 15454 SDH. The IEEE 802.1Q VLAN tag logically isolates traffic (typically subscribers).

Multiple E-Series Ethernet cards installed in an ONS 15454 SDH can act together as a single switching entity or as independent single switches supporting a variety of SDH port configurations.

You can create logical SDH ports by provisioning a number of SDH channels to the packet switch entity within the ONS 15454 SDH. Logical ports can be created with a bandwidth granularity of VC-4.

5.3.1 E1000-2-G Compatibility

The E1000-2-G is compatible with any traffic card slots (Slots 1 to 6 and 12 to 17).

5.3.2 E1000-2-G Card-Level Indicators

The E1000-2-G card faceplate has three card-level LED indicators (Table 5-5 ).

Table 5-5 E1000-2-G Card-Level Indicators

Chapter 5 Ethernet Cards

Card-Level Indicators Description

Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready or that a

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. If the

ACT LED is green it indicates that the E1000-2-G card is active and the software is operational.

SF LED Not used in this release.

5.3.3 E1000-2-G Port-Level Indicators

The E1000-2-G card also has one bicolor LED per port (Table 5-6). When the LINK LED is illuminated green, carrier is detected, meaning an active network cable is installed. When the LINK LED is not illuminated green, an active network cable is not plugged into the port, or the card is carrying unidirectional traffic. The port ACT LED flashes amber at a rate proportional to the level of traffic being received and transmitted over the port.

Table 5-6 E1000-2-G Port-Level Indicators

LED State Description

Amber The port is active (transmitting and receiving data).

Solid green The link is established.

Green light off The connection is inactive, or traffic is unidirectional.
