Chapter 1: Introduction
1-4 6E128-26, 6E138-25, 6E129-26 and 6E139-25 User’s Guide
1.3.1 Connectivity
The 6E128-26 and 6E138-25 connect to Ethernet networks or
workstations through 24 ST fiber optic ports on the front panel. These
ports support multimode fiber optic cables at lengths up to 2 kilometers.
The ports are IEEE 802.3 10BASE-F compliant.
The 6E129-26 and 6E139-25 connect to Ethernet networks or
workstations through 24 ST fiber optic ports on the front panel. These
ports support single mode fiber optic cable at lengths up to 5 kilometers.
The ports are FOIRL compliant.
The 6E12X-26 modules have two front panel slots (ports 25 and 26) for
optional Fast Ethernet Interface Modules to support an uplink to
100 Mbps Ethernet backbones or a high speed connection to a local
server.
The 6E13X-25 modules have one front panel slot for an optional High
Speed Interface Module to provide for additional connectivity to other
high speed networking technologies such as ATM, WANs, Gigabit
Ethernet and FDDI.
1.3.2 Full Duplex Switched Ethernet
Each switched Ethernet port supports full wire-speed Ethernet
communications and can be configured to operate in Full Duplex
Switched Ethernet mode, which provides 20 Mbps of bandwidth.
The optional Fast Ethernet Interface Modules for the 6E12X-26 can also
be configured to operate in Full Duplex Switched Ethernet mode, which
provides 200 Mbps of bandwidth.
1.3.3 Management
Management of the 6E12X-26 and 6E13X-25 is accomplished using
Local Management tools or remote SNMP management stations. Local
Management is accessible through the RS232 COM port on the front
panel using a local VT100 terminal, or a remote VT100 terminal via a
modem connection, and in-band via a Telnet connection. In-band remote
management is possible through any SNMP compliant Network
Management Software.
