Laser Safety - Fiber Output SFP and QSFP Modules Warning

Mains Supply Voltage

Before connecting the equipment, observe the safety warnings section and ensure that the
local mains supply is within the rating stated on the rear of the equipment.

LASER SAFETY

The average optical output power does not exceed 0 dBm (1mW) under normal operating
conditions. Unused optical outputs should be covered to prevent direct exposure to the
laser beam.

Even though the power of these lasers is low, the beam should be treated with caution
and common sense because it is intense and concentrated. Laser radiation can cause
irreversible and permanent damage of eyesight. Please read the following guidelines
carefully:

• Make sure that a fiber is connected to the board's fiber outputs before power is
applied. If a fiber cable (e.g. patchcord) is already connected to an output, make sure
that the cable's other end is connected, too, before powering up the board.

• Do not look in the end of a fiber to see if light is coming out. The laser wavelengths
being used are totally invisible to the human eye and can cause permanent damage.
Always use optical instrumentation, such as an optical power meter, to verify light
output.

Environmental Considerations

This chapter instructs the user how to install the control surfaces, mainframe and any
ancillary panels into desktop and 19 inch rack environments. Attention should be paid to
the cooling information for the mainframe.



The ambient temperature for all the supplied equipment should not exceed the limits of 5
and 40

°C (41 to 104F) at a relative humidity of 10 to 90% (non-condensing).

Installing the equipment in a clean environment with moderate temperature and humidity
will promote a long and trouble-free equipment life.

Control Surfaces

Mounting a Kula Control Surface into a Desk

With the desk cut to the correct size, desk cut-out information can be found on:

• 24 crosspoint (KPX and K1X) cutout diagrams on pages 37 and 38.

• 16 crosspoint (K1P and KPP) cutout diagrams on page 41.

The Control Surface is secured into a desk using appropriate “Pan Head” M4 screws with a
Max. head diameter of 8.8mm [0.34 Inches]. At each end of each Control Surface, there are
two 4.5 mm [0.18 Inches] fixing point holes for the screws (as shown on the diagram below).

Note: The Kula control surface should preferably be mounted in a desk
which is open underneath.
Note: If the desk is not open underneath, enough room has to be left
underneath for ventilation and for routing the PSU and Comms cables to the
underside of the control surface.

Note: It is essential to ensure the air temperature does not exceed 40°C.

Air Flow through the Mainframe

The Kula mainframe can be used freestanding (tabletop configuration) or installed in a
standard 483mm (19 inch) equipment rack. The following precautions should be observed:

1 The air intakes on both sides and the cooling fan exhausts at the rear of the unit must

not be obstructed - a minimum clearance at the rear of the mainframe of 200mm (8
inches) is ESSENTIAL.

2 Air intakes situated at the front and on both sides, are to allow the inlet of cooling air

and MUST NOT BE OBSTRUCTED.

Cooling Fan Failure

IF THE COOLING FANS ONTHE SWITCHER MAINFRAME SHOULD STOP FOR ANY REASON,
THEN THE SYSTEM SHOULD BE SWITCHED OFF IMMEDIATELY OR PERMANENT DAMAGE
MAY RESULT.



Depending on the length of time the mainframe has been run with no fan the unit may
need to be returned for checking and repair. Contact Grass Valley or your Grass Valley
dealer to discuss the situation.

Mainframe Location and Environment

Mounting the Kula Mainframe into a 19” Rack

The Mainframe will require an 2RU space within a rack system. Please read the above
warning before attempting to fit the mainframe into a rack.

1 Check that the rack is rigid enough for the mainframe.
2 A suitable rack tray will be needed in the rack to take the weight of the

mainframe. The mainframe rear will become heavier when the BNC cables are
connected.

3

4 When in position in the rack, there are 2 pre-cut slots (mounting holes) running down

each side of the front of the mainframe, to access the mounting holes, the mainframe
front door will have to be opened. To do this; unscrew the door locking screws on either
side of the door, then pull outwards and lower (as shown in the diagram below).

5 The mainframe is fastened to the rack system using 4x M6 (1/4 inch) screws (screws are

available from rack suppliers).

Note: The Kula Mainframe is heavy (14kg – 30.3lb) and will require two
people to lift into position, using correct lifting procedures. If you are unsure
of the lifting procedures, ask a Health and Safety adviser for information.

Note: If the rack tray has sides, make sure that they do not block the
ventilation holes on the sides of the mainframe.

2x screws on each side attach
the mainframe to the rack

Half 19" Rack Mount

The mounting brackets may also be set to a vertical position to fit the unit into a 19" rack,
the unit is 1RU high and only half 19" wide, so will need to have support from below using a
rack mount tray, as only one side of the unit can be secured to the rack sides.

19” Rack Mount using two Mav Remote units with a Joining Plate

Two Mav Remote units can be joined together using a joining plate, which allows the units
to span across the full width of the rack and fasten to the rack without the support of a rack
tray.

Note: The Mav Remote must have ventilation to allow cooling, and must
not be installed into an enclosed space.

The unit is secured to the
rack on one side only.

Power Supplies

Mainframe Internal Power Supplies

The information below gives an overview of the power supplies used in the Kula
mainframes.

The Kula Mainframe is supplied as standard with two power supplies, one power supply is
able to run a fully populated mainframe. The other power supply is for redundancy.

This symbol indicates that hazardous voltages are present inside. No User Serviceable
Parts inside the power supplies. This unit should only be serviced by trained personnel.

The power supplies for the Kula mainframe are retained within the mainframe body, there
are no On/Off switches for the power supplies. The mainframe will power up as soon as the
AC Power Cables are plugged into the IEC connectors and turned On at the AC mains
supply.

Checking the Kula Power Supplies

Kula mainframe power supplies are hot-swappable. Replacing power supplies should only
be attempted by qualified personnel.



To see that the power supplies are working correctly, when mains power is applied, a green
power LED is lit (as shown below).

With the power supplies un-plugged from the mains supply, they can be individually
removed by unscrewing the removal screws and carefully withdrawing the PSU from the
body of the mainframe.

Note: To reduce the risk of electric shock, plug each power supply cord into
separate branch circuits employing separate service grounds.

Note: To ensure full dual redundancy, the two power supplies must be
powered from independent power sources.
