LTC 8901 Series CPU Design Features

The LAN switches provide the interbay communication for the system. Since all
systemcommunication is routed through these switches, the use of only one switch would
make the system vulnerable to a single point failure. The redundant configurations of the LTC
8900 system are therefore supplied with a minimum of two switches.
The LAN switches are standard 10/100Base-T ethernet switches. Data connections are made
using unshielded twisted pair wire with RJ-45 modular connectors. On the LTC 8944/93 and
LTC 8945/93 switches, the factory preconfigures port 1 to accept CPU communication and
port 2 to accept System Controller PC communication. The switches are also factory
preconfigured so that any data entering ports 3 through 12 is sent to all other ports. A special
LAN cable connection (shown in , page 32) provides a data path between the two switches.
