Rack mounting the system

Rack-mounted

cooling

Once mounted in a rack, it is important that there is adequate airflow at the rear
of the laser so that the cooling fins can effectively dissipate the heat generated
by the laser – see

“Heat dissipation” on page 29

Forced air cooling

When multiple ACOUSTIK system are installed in a single rack, it is
recommended to use forced air cooling. .

Figure 10

Cooling a multiple system installation

Note:

The vibration sensitivity of the installed laser modules requires rack cooling

fans installed with vibration isolation.

Blank covers

For systems that are not fully populated, place a blank cover over each
unoccupied slot.

Figure 11

shows blank covers installed in slot positions 10 and 11.
