Removing and Installing an I/O Board or Blank
Panel
The FOX 4G Matrix 14400 fiber optic I/O boards
W
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.
See "A note on I/O boards", on page 2-2, to understand the
N
different arrangement of connectors on the I/O boards.
Circuit boards can be replaced for fault correction. They also
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:
N The I/O boards are hot-swappable. You do not need to
power down the switcher to remove an I/O board.
1. For an I/O board, disconnect any connected cables.
2. Rotate the left and right knurled knobs to completely
loosen the captive screws.
3. Gently pull on the knurled knobs/captive screws to loosen
the board or panel from the backplane.
4. Slide the board or panel out of the chassis (next page).

C 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) is on the left and
transceiver module P 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.
N If necessary, use a screwdriver to tighten the knurled
knobs/captive screws.
