Cisco 4OC12X/ATM-BLANK is a blank filler panel for ISE ATM linecards that maintains chassis airflow balance and dust protection.
The 4OC12X/ATM-BLANK panel is required for use in Cisco 12008 and 12012 chassis equipped with ISE ATM linecards.
A blank panel prevents airflow leakage, dust ingress and maintains correct cooling in chassis slots without active modules.
Align the blank with the empty ISE ATM slot, insert gently until it clicks, and secure with the provided captive screw.
Install one 4OC12X/ATM-BLANK panel for each unused ISE ATM linecard slot to ensure optimal airflow and dust protection.
Yes, the 4OC12X/ATM-BLANK panel is fully reusable and can be reinstalled whenever slot configurations change.
No. The blank panel optimizes cooling by sealing empty slots, directing airflow through active linecards only.
The panel measures 1.75”×8.5”×0.25” and is constructed from ABS plastic with a corrosion-resistant finish.
Yes. Each panel ships with a captive stainless-steel screw for secure installation in Cisco chassis.
No. Install or remove the blank panel only when the chassis power is off to avoid airflow disruptions.
