Essential for maintaining proper airflow in our 12012 chassis. This blank fits perfectly and keeps our line cards running at optimal temperatures.
Simple but vital. This blanking plate is sturdy and ensures that our modular chassis meets thermal and EMI standards. Very satisfied with the quality.
A necessary accessory for any professional rack. It fits securely and prevents dust accumulation while directing airflow to active line cards.
Durable construction and a perfect fit. These blanks are a cost-effective way to ensure the longevity of our core router hardware.
High-quality material and finish. It's a small part of the system but critical for the structural and thermal integrity of our 12K routers.
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.
Order through your Cisco authorized reseller or the Cisco e-Procurement portal using SKU 4OC12X/ATM-BLANK.
Lead time varies by region but typically ranges from 3 to 5 business days when in stock.
The blank panel is covered under Cisco’s standard hardware warranty for defects in materials and workmanship.
Download the official datasheet from Cisco’s website by searching for SKU 4OC12X/ATM-BLANK in the documentation library.
Verify slot type and chassis model (12008/12012) in your system guide or use Cisco’s online compatibility matrix.
By sealing unused slots, the panel prevents dust buildup and uneven cooling, reducing hardware failures and maintenance needs.
