Installing the I/O board or blank panel
N
The I/O boards are hot-swappable. You do not need to power down the switcher
to install an I/O board.
Install an I/O board or blank panel as follows:
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. ESD can damage circuits, even if you
cannot feel, see, or hear it.
1. 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
2. For an I/O board, align the board with the left and right chassis guides
(figure 7-2).
3. 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.
4. Gently seat the board or panel in the backplane.
5. 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.
Removing and Installing the Power Supply Module
Removing the power supply module
The two power supply modules (primary power supply and redundant power
supply) are identical and hot-swappable. Each power supply module has a
2-color LED, visible on the rear panel, that indicates the status of the power supply
outputs. If the LED is lit green, the power supply is operating normally. If the LED
is lit red, the supply has failed and should be replaced at the earliest opportunity.
N
The power supply modules are hot-swappable. Either power supply can be
removed without powering down the switcher.
Remove a power supply module as follows:
1. Rotate the left and right knurled knobs to completely loosen the captive
screws.
2. Gently pull on the handle to loosen the power supply from the backplane
(figure 7-3).
3. Slide the power supply out of the chassis.
