How to Replace Modules
How to Install or Replace Input/Output Cards
Note: No shutdown is required prior to installing/replacing Input/Output
Cards.
Step 1
Turn the two thumbscrews counterclockwise until they disengage from the chassis. Pull the
card out using both handles.
Warning! Do not pull on the thumbscrews when removing the module –
damage may occur!
OR
If a blank panel is present, remove the blank panel from the desired location using the
thumbscrews.
Step 2
Place the new module upright so that the POWER LED is on the top. Grasp the module
by the handles or by the outer edge of the aluminum housing. The card should slide freely
until it reaches the backplane connector. At this point, use just enough force to firmly
engage the card with the mating connector.
Warning! If the module does not slide into the connector, do not force it!
Damage may occur. Remove the card and start over.
Step 3
Once the module is completely seated, hand-tighten the thumbscrews.
Warning! Do not tighten the thumbscrews with a screwdriver.
