2.2 Installing cards in the FRM-501 Integrity
TM
System Frame
The FRM-501 Integrity System Frame can hold a maximum of four cards, but it is recommended that no
more than two cards be inserted in the frame.
1.
Carefully load cards through the rear of the frame (see diagram below for slot numbers for placing
the card in the frame).
2.
Card guides at the sides 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 the card is seated into the mating connector, secure the card using the two captive screws.
