and 8-port multi-service access (MSA8) DS1 or E1 FPs.
• If you install termination panels in the back of a seismic cabinet containing
Nortel Multiservice Switch 7480s, leave some rack space between the
termination panels for each device This space aids airflow through the
cabinet and provides space for cables.
