Removing and Installing an I/O Board or Blank

Panel

W

The FOX 4G Matrix Switchers fiber optic I/O boards

output continuous invisible light, which may be

harmful and dangerous to the eyes; use with caution.

• Do not look into the rear panel fiber optic

cable connectors or into the fiber optic cables

themselves.

• Plug the attached dust caps into the optical

transceivers when the fiber optic cable is

unplugged.

N

As factory configured, the fiber optic I/O boards are

configured as either 100 percent singlemode or 100 percent

multimode, but you can remove a fiber optic transceiver

module (one input and one output) of one transmission

mode and replace it with a block of the other transmission

mode.

You can mix transmission mode transceiver modules on

a fiber optic I/O board, provided that you ensure that

each fiber cable and connected devices are the appropriate

transmission mode for the transceiver module.

Typically, singlemode fiber has a yellow jacket and

multimode cable has an orange jacket.

N

For proper cooling and air flow, boards and/or blank panels

should be installed in all locations during normal switcher

operations.

N

See "A note on I/O boards", on page 2-2, to understand the

different arrangement of connectors on the I/O boards.

Circuit boards can be added or removed to increase or decrease

the I/O configuration (size) of the switcher.
Remove and replace and I/O board or blank panel as follows:

The I/O boards are hot-swappable. You do not need to

power down the switcher to remove an I/O board.

Do not touch the electronic components or the

connectors on the backplane or on the circuit boards

without being electrically grounded. Handle circuit

boards by their edges only. Electrostatic discharge can

damage circuits, even if you cannot feel, see, or hear it.

5

.

Place the removed board on an anti-static surface or in an

anti-static container.

6

.

For an I/O board

, orient the board to be installed so

that transceiver module A (fiber board) or input BNC A

(SDI/HD-SDI board) is on the left and transceiver module

or output BNC H is on the right.

7

.

For an I/O board

, align the board with the left and right

chassis guides (above).

8

.

Gently slide the board or blank panel into the enclosure.

For an I/O board, slide the board toward the front panel

until it meets resistance.

9

.

Gently seat the board or panel in the backplane.

10

. Tighten the left and right knurled knobs/captive screws to

lock the board or panel in place.
