72 APEX — Installation and Service Manual

Section 3 — Installation

4. Make sure all cards are all seated in their backplane sockets.

This should not normally be an issue since the boards are held in place

with locking extractors.

5. On multi-chassis systems, InfiniBand

and Master Clock cables must

be used to connect the frames. The cables cannot be longer than four

meters, See Expanded (Multi-Chassis) Systems on page 79.

Note InfiniBand cables must be installed correctly to ensure proper system

operation. When a cable is mis-wired, it will not be automatically

detected by the system.

If two or more frames of a multi-frame standard Apex system must be

located more than four meters apart, 2 each model APX-FBR-EXT Apex

Fiber Extenders must be installed for each remote chassis. See

Fiber

Extenders (Standard Apex Only) on page 85.

6. Connect the audio signal cables.

The 110 Ohm version of the switcher uses D connectors, with each

input/output using three pins: one for (+) positive, one for (-) negative

and one for Ground. A drawing of the pin numbering scheme is shown

at the bottom of

Figure 27 on page 77.

7. Connect the appropriate house reference signal(s).

Each chassis must have a house video reference or an AES reference in

order for switches to occur on the proper audio frame boundary.

Factory default settings on the CX-34000 Control XPT board assume

that a video reference signal used to synchronize AES audio will be con

nected to the VID REF A connector.

If there are two Matrix boards installed, they must both be connected to

the same reference signal, they will automatically operate in redundant

mode; i.e., if one board fails the other will become active and synchro

nization maintained. For example, a video black burst signal used as an

AES reference would be looped through VID REF A and VID REF B and

terminated.

8. Check the DIP switch settings on the CX-34000 Control Crosspoint

board. See CX-34000 Control Crosspoint Board Configuration on page 94.

This board is used when the router is controlled through a crosspoint

bus connection (all present systems).

If redundant CX-34000 control crosspoint boards are used, the configu-

ration switches must match to ensure proper operation of the router.

9. If output monitoring is required, refer to the installation instructions

starting on Output Monitoring on page 99.
