Chapter 5 Ethernet Cards
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 (Table 5-3).
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
(Table 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.
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.
Table 5-3 E100T-G Card-Level Indicators
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.
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.
