Overview
6H123-50 and 6H133-37 User’s Guide 1-5
Table 1-1 shows the port organization for both modules.
1.3.1 Connectivity
The 6H123-50 and 6H133-37 connect to Ethernet/Fast Ethernet networks
or workstations through RJ21 ports on the front panel. Each port supports
a 25-pair cable at lengths up to 100 meters (each pair must be Category 5
compliant with an impedance of 85 to 111 ohms). The ports are IEEE
802.3 10BASE-T and IEEE 802.3u 100BASE-TX compliant.
The 6H123-50 has two front panel slots (connectors 5 and 6 or interfaces
9 and 10) for optional Fast Ethernet Interface Modules to support an
uplink to Fast Ethernet backbones or a high speed connection to a local
server.
The 6H133-37 has one front panel slot for an optional High Speed
Interface Module (Interface 7) to provide for additional connectivity to
other high speed networking technologies such as ATM, FDDI, and
WANs.
Cables available for 100BASE-TX operation include the following:
• 180° angle connector (straight-through RJ21-to-RJ21)
• 180° RJ21-to-RJ45 connector
• 120° angle connector with the same options
