DescriptionThese two modules are PCBs intended to be inserted in a card cage. There is an extraction handle attached to the front of the card, on which a paper label containing the model number, serial number, and other information is printed.
Opposite the handle there are 47 bifurcated gold-plated contacts arranged in two rows. Mounted on the component side of the PCB are the active and passive components, consisting mainly of transistors, diodes, resistors, capacitors, and jumpers.
All the cards have various quality control stamps on one or both sides of the PCB.
