Installing RIC-E1/R into the ASM-MN-214 Card Cage
To install the RIC-E1/R card in the ASM-MN-214 card cage:
1. Install the ASM-MN-214 card cage in the 19-inch rack.
2. Insert the RIC-E1/R card into one of the ASM-MN-214 slots.
3. Push the card into the cage until it is fully inserted into the edge connector
inside the rack.
