5.3 Card insertion
After the front panel is removed, full access to the card modules inside the sub-rack is
given.
Switch off the power with the power switch on the power-supply modules. The green
light on the power module is now switched off. If the power supply is redundant, make
sure that both power supplies are off.
The sub-racks are equipped with plastic guide rails to align the module cards into their
respective positions 1 to 10. Just before the cards are inserted one should remove the
plastic cap from the fiber ferrule as shown in figure 11. Do not touch the ferrule tip with
your fingers (see chapter 6.2 - fig. 21).

Be careful when inserting the card into the sub-rack.
The ferrule of the fiber may be damaged if it touches the sub-rack walls. Do
not touch the ferrule tip with your fingers.
