NoteThe 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.
NoteEach 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.

5.1.1 Cards Summary
Table 5-1 lists the Cisco ONS 15454 SDH Ethernet cards.
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.

5.2 E100T-G Card
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
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 - 3E 10 0 T- G C a r d - L e v e l Indica to r s
Card-Level IndicatorsDescription
Red FAIL LEDThe 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 LEDA 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 LEDNot 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 5-4E100T-G Port-Level Indicators
LED StateDescription
AmberPort 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 GreenLink 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 5-5E1000-2-G Card-Level Indicators

Card-Level IndicatorsDescription
Red FAIL LEDThe 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 LEDA 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 LEDNot 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 5-6E1000-2-G Port-Level Indicators
LED StateDescription
AmberThe port is active (transmitting and receiving data).
Solid greenThe link is established.
Green light offThe connection is inactive, or traffic is unidirectional.
