Overview Of 4OC12X/ATM-BLANK
The Cisco 12000 Line Card 4OC12X/ATM-BLANK is a blank module designed for ISE (IP Services Engine) ATM Linecards in the Cisco 12008 and 12012 chassis. This blank module covers and secures empty slots in the chassis where an ISE ATM Linecard is not installed. In networking environments where certain slots in the Cisco 12008 or 12012 chassis are not occupied by active Linecards, the 4OC12X/ATM-BLANK is utilized to maintain proper airflow, structural integrity, and safety within the chassis. These blanks help create a barrier, preventing dust and debris from entering unused slots. This blank module is a necessary accessory for securing the optimal performance and longevity of the Cisco 12000 Series routers, particularly when specific slots are not in use or are being reserved for future Linecard installations.
