Keep airflow aligned with the platform design using this Cisco air deflectors set for MSTP M2 and NCS 2002 systems. In dense optical and transport environments, small airflow changes can have outsized effects on thermal stability. This accessory helps preserve the intended air path so the chassis can operate under the conditions it was engineered for. For infrastructure teams, the value is in precision. A matched deflector set is more than a convenience part — it is a practical way to maintain cooling behavior during installation, replacement, or service events. That matters when the rack is carrying critical transport equipment and downtime is expensive. Use this set when you need a platform-specific airflow component for Cisco MSTP M2 or NCS 2002 hardware. It is designed to support the original thermal layout rather than approximate it, which is exactly what production environments require.
