Cisco ONS 15454 Installation and Operations Guide, R3.2
March 2002
Chapter 9 Ethernet Operation
E Series Multicard and Single-Card EtherSwitch
9.2.5 E-Series Gigabit Interface Converters
Gigabit interface converters (GBICs) are hot-swappable input/output devices that plug into a Gigabit
Ethernet card to link the port with the fiber-optic network. The type of GBIC determines the maximum
distance that the Ethernet traffic will travel from the card to the next network device.
The E1000-2/E1000-2-G card supports SX and LX GBICs.
1000BaseSX operates on multi-mode fiber optic link spans of up to 550 m in length. 1000BaseLX
operates on single-mode fiber optic links of up to 10 km in length.
Table 9-4 shows the available GBICs.
For GBIC installation and cabling instructions, see the “Fiber-Optic Cable Installation” section on
page 1-52.
Caution Use only GBICs certified for use in the ONS 15454 E1000-2/E1000-2-G card, Cisco product numbers
15454-GBIC-SX and 15454-GBIC-LX.
Caution E1000-2/E1000-2-G cards lose traffic for approximately 30 seconds when an ONS 15454 database is
restored. Traffic is lost during the period of spanning tree reconvergence. The CARLOSS alarm will
appear and clear during this period.
9.3 E Series Multicard and Single-Card EtherSwitch
The ONS 15454 enables multicard and single-card EtherSwitch modes for E series cards. At the Ethernet
card view in CTC, click the Provisioning > Card tabs to reveal the Card Mode option.
9.3.1 E Series Multicard EtherSwitch
Multicard EtherSwitch provisions two or more Ethernet cards to act as a single layer 2 switch. It supports
one STS-6c shared packet ring, two STS-3c shared packet rings, or six STS-1 shared packet rings. The
bandwidth of the single switch formed by the Ethernet cards matches the bandwidth of the provisioned
Ethernet circuit up to STS-6c worth of bandwidth.
