Blank!cards!
The E7-20 “Blank” cards are designed to fill all empty access card and SCP card slots. A
common E7 BLANK card is used in both the E7-2 and E7-20 and must be placed in any
empty slot to ensure proper airflow and cooling for normal operations. The blank card keeps
“forced air” from escaping out the front of the shelf and is required to comply with
Electromagnetic Interference (EMI) standards.
Note:
Blank cards must be ordered separately.
