Customers should have no reason to remove the fan unit.

The CQX video routers have a “mode” switch in addition to the 16-position frame ID switch. Both
are 16-position rotary switches that turn with a small screwdriver. The “mode” switch configures
the video format of the router.

Set the rotary switch to a position in the range 0–9, A, B, C, or D, according to this table:

The default is 1080i, 59.94 Hz (switch setting 0). Positions E and F are not valid positions.

Where a switch setting supports multiple formats, the format is governed by the video reference
applied to the router and must be compatible with that reference format.

The CQX routers enter non-sync bypass mode for signals at all other rates.

Every time you make a switch change, power-cycle the router.

Settings 6 and 7 are for SMPTE 425 level A. Settings 8 and 9 are for SMPTE 425 level B.

Analog Video Routers

The 1RU analog video routers have 16×16, 16×4, or 8×8 crosspoints. The 2RU analog video
routers have either 32×32 or 32×4 crosspoints.

Figure A-23 shows a simplified view of an analog video router:

The analog video routers switch NTSC (525i) or PAL (625i) video signals. The router outputs are
switched in sync with an external video reference if it is present.
