8901 Series CPU
Note that the LTC 8943/95 System Controller PC is supplied with a third LAN port. This port is
available for connecting the PC to the user s Ethernet network. Only those with advanced
knowledge of Windows and network installations should attempt to use this interface.
A rear panel diagram of the LTC 8901 Series CPU is shown in , page 66.
6.14.2
LTC 8902 Series and LTC 8903 Series Data Connections
Data connections for LTC 8902 Series and LTC 8903 Series bays are shown in , page 66.
Each LTC 8902 Series bay and LTC 8903 Series bay has two LAN connectors. Either of these
connectors can be used, although only one should be connected at a time. The supplied
standard 8 m (25 ft) 10/100Base-T twisted pair cable is used to connect from the LAN
connectors on the LTC 8902 Series and LTC 8903 Series bays to any of the ports on any of the
10/100Base-T switches.
The LAN connections should be spread across LAN switch #1 and LAN switch #2 in a manner
to minimize the impact of a switch failure to the system. For example, in a system with 128
monitor outputs, one LTC 8902 Series bay and all of its associated LTC 8903 Series bays can
be connected to one LAN switch. The second LTC 8902 Series bay and its associated LTC
8903 Series bays should be connected to the other LAN switch. This way, half of the system
(either monitors 1 to 64 OR monitors 65 to 128) will remain in operation in the unlikely event
of a LAN switch failure.
The number of available LAN switches in the system can be expanded using additional LTC
8946/93 LAN switches. Each LTC 8946/93 provides 10 additional ports, which are only
required in large systems having more than a combined total of 18 LTC 8902 Series and LTC
8903 Series bays.
6.14.3
LTC 8944/93 LAN Switch to LTC 8945/93 LAN Switch Connections
The LAN switches must be connected together using the supplied 2 m (6 ft) crossover LAN
cable. Connect the LAN cable between any two ports on the two LAN switches.
6.14.4
LTC 8946/93 LAN Switch Connections
When the combined quantity of LTC 8902 Series and LTC 8903 Series matrix bays exceeds 18,
1 or more expansion LTC 8946/93 LAN switches are required. Each LTC 8946/93 expansion
switch provides an additional 10 ports for connection to matrix bays.
Connect the supplied 2 m (6 ft) crossover cable from any port of the expansion LTC 8946/93
LAN switch to any port located on either the LTC 8944/93 or LTC 8945/93 LAN switch. Any
additional LTC 8946/93 LAN switches would be connected in a similar manner to any available
LTC 8944/93, LTC 8945/93, or LTC 8946/93 LAN switches. These data connections are
illustrated in , page 66.
6.14.5
LTC 8943/95 PC to LTC 8945/93 LAN Switch Connectors
The LTC 8943/95 System Controller PC connects to the LTC 8944/93 and LTC 8945/93 LAN
switches using the supplied standard 3 m (10 ft) 10/100Base-T twisted pair cables. Connect
one cable from the Primary LAN interface board on the rear panel of the PC, to port 2 of the
LTC 8944/93 LAN switch (switch labeled Primary IP address).
Connect another 3 m (10 ft) LAN cable from the Backup LAN interface board on the rear panel
of the PC to port 2 of the LTC 8944/93 LAN switch (switch labeled Backup IP address). These
data connections are illustrated in , page 66.

Main Power Connections
Install the supplied AC power cords between the equipment and the appropriate AC power
source. Verify that the AC power switches (on applicable components) are initially set to OFF.
