5.3 Main module insertion
After the fan front is removed, full access to the card modules inside the frame is given.
Switch off the power with the power switch at the power-supply modules. The green light --
at the power module is now switched off. If the power supply is redundant, make sure that
both power supplies are off.
The frames are equipped with plastic guide rails to align the module cards into their
respective positions 1 to 20. Just before a card is 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 Error! Reference source not found. - fig. 21).
