System Data Connections
LTC 8904 Series CPU Data Connections
The LTC 8904 Series CPU connects to the LTC 8946/93 LAN switch using a supplied standard
8m (25ft) 10/100Base-T twisted pair cable. The LAN cable can be connected to any port of the
LTC 8946/93 LAN switch.
LTC 8902 Series and LTC 8903 Series Data Connections
Data connections for LTC 8902 Series and LTC 8903 Series bays are shown in , page 68.
Each LTC 8902 Series bay and LTC 8903 Series bay has two LAN connectors, but either of
these connectors can be used. Only one at a time should be connected. The supplied standard
8 m (25 ft) 10/100Base-T twisted pair cable is used to connect the LAN connectors on the LTC
8902 Series and LTC 8903 Series bays to any of the ports on any of the LTC 8946/93 LAN
switch(es).
The number of available LAN ports can be increased by cascading multiple LTC 8946/93 LAN
switches. Each LTC 8946/93 provides 10 additional ports. Additional ports are only required in
large systems with more than a combined total of 11 LTC 8902 Series and LTC 8903 Series
bays.
Multiple LTC 8946/93 LAN Switch Connections
When the combined quantity of LTC 8902 Series and LTC 8903 Series matrix bays exceeds 11,
use 1 or more additional LTC 8946/93 LAN switch(s). Each additional LTC 8946/93 switch
provides 10 additional ports for connection to matrix bays.
Connect the supplied 2 m (6 ft) crossover cable from any port of the second LTC 8946/93 LAN
switch to any port located on the first LTC 8946/93 LAN switch. Connect any additional LTC
8946/93 LAN switches similarly. These data connections are illustrated in , page 68.
Main Power Connections
Install the supplied AC power cords between the various pieces of equipment and the
appropriate AC power source.
Verify that the AC power switches (on applicable components) are initially set to OFF.
The order that power is supplied to the system is not critical, but the following order is
recommended if unfamiliar with the equipment:
Apply power to the LTC 8946/93 LAN switch(es). The LAN switches do not have a main AC
power switch, and should power up as soon as the main AC power cord is connected.
Switch on the main AC power to the video bays (LTC 8902 and LTC 8903).
Verify that the LEDs associated with the fuses are lit on all of the power supplies located in
the LTC 8902 Series and LTC 8903 Series matrix bays.
Initially, the modules within the matrix bays should indicate the following conditions:
– The CPU ACT. LEDS on all Data Receiver modules (module next to power supply)
installed in the various matrix bays should blink randomly green. The LAN LINK/ACT LED
will blink green to indicate communication with the Allegiant CPU. The LAN DUP/COL
LED illuminates yellow to indicate a full duplex network link exists with the Allegiant CPU.
All other LEDs can be ignored.
– Activity LEDs should be blinking on the video input and output modules installed in the
matrix bays.
Apply power to the LTC 8904 Series CPU bay. The LTC 8904 Series CPU does not have a main
AC power switch, and should power up as soon as the main AC power cord is connected. The
front panel power LED should be lit and the Activity LED should blink.
