1.3 OVERVIEW
The 6H122-16 ( Figure 1-1 ) is a Fast Ethernet interface module for the
Cabletron Systems 6C105 chassis. The module provides sixteen RJ45
switched ports for unshielded twisted pair (UTP) cabling connectivity.
The 6H122-16 is used to connect individual high-bandwidth user devices,
such as workstations, and provide a central switching point for multiple
10/100 Mbps Fast Ethernet segments.
1.3.1 Connectivity
The 6H122-16 connects to Ethernet/Fast Ethernet networks or
workstations through sixteen RJ45 ports on the front panel. These ports
are IEEE 802.3u 100BASE-TX compliant, and use Category 5 unshielded
twisted pair cables of lengths up to 100 meters with impedances between
85 and 111 ohms.
1.3.2 Management
Management of the 6H122-16 module and 6C105 chassis and any
optional equipment is accomplished using Local Management tools or
remote SNMP management stations. Local Management is accessible
through the front panel RS232 COM port using a local VT100 terminal,
or a remote VT100 terminal via a modem connection. Local Management
is also accessible in-band via a Telnet connection. In-band remote
management is possible through any SNMP compliant Network
Management Software.
