2.1 Installing cards in the FRM-504 Integrity
TM
System Frame
The FRM-504 Integrity System Frame can hold a maximum of 18 cards, but it is recommended that no more
than 16 cards be inserted in the frame.
1.
Carefully load cards through the rear of the frame.
•
Card slot number 1 is nearest to the power supply side.
•
Card slot number 18 is farthest from the power supplies.
2.
Card guides at the top and bottom of each slot are used to align the card with the mating connector
on the mid-plane card as the card is inserted fully into the frame.
3.
After cards are gently seated into the mating connector, secure them to the top and bottom rail of the
frame using the two captive screws attached to each card.
