 To insert the cards and power supply into the chassis
1 Ensure that there are no obstructions in the guide rails for each of the three slots and check the
backplane for bent pins.
If there are bent pins, the backplane is damaged and requires repair. Report any damaged equipment to
your SOMA Networks representative as soon as possible.

ii Set the ejector handles on the in the open position by turning the handles away from the center of
the front panel.
iii In the open position, the ejector handles are at an approximately 45° angle from the front panel.
iv Ensure that the mounting screws are withdrawn enough to allow for the insertion of the card.
v Orient the card so that the text on the front panel is right-side up. The guide pins should be located
to the right of the ejector handles.

ensure the connectors are aligned.
vii Apply sufficient pressure to fully mate the card by pressing on both ejector handles with equal force.
If present on the card, the guide pins should slide into the round holes located at the top and the
bottom of each slot on the right-hand side.
