1.3 OVERVIEW
The 6H123-50 and 6H133-37, shown in Figure 1-1 , are interface modules
for the Cabletron Systems 6C105 SmartSwitch 6000 chassis.
The 6H123-50 and 6H133-37 are high-speed network repeater/switch
devices. The 6H123-50 provides four Ethernet repeated segments and
four Fast Ethernet repeated segments (CONN 1 through CONN 4). The
6H133-37 provides three Ethernet repeated segments and three Fast
Ethernet repeated segments (CONN 1 through CONN 3). The RJ21
connectors each consist of 12 repeater ports that are able to reside on the
Ethernet (10 Mbps) or the Fast Ethernet (100 Mbps) segment. Each
Ethernet and Fast Ethernet segment supports 802.1D switching
(bridging), Cabletron Systems SecureFast Switching Virtual Network
technology and IEEE 802.1Q Port Based VLANs.
Slots 5 and 6 (interfaces 9 and 10) of the 6H123-50 support optional Fast
Ethernet Interface Modules providing uplinks to 100BASE-TX or
100BASE-FX Fast Ethernet networks. The 6H133-37 is capable of being
equipped with a High Speed Interface Module (HSIM) that provides for
additional connectivity to other high speed networking technologies such
as Asynchronous Transfer Mode (ATM), Fiber Distributed Data Interface
(FDDI) and Wide Area Network (WANs).
The 6H123-50 and 6H133-37 switch each Ethernet and Fast Ethernet
segment (CONN 1 through CONN 4 and CONN 1 through CONN 3) to
one another and to the optional Fast Ethernet Interface modules of the
6H123-50 or an HSIM installed in the 6H133-37.
