- Two redundant monitored cooling fans
- Designed for MACH 3002 and MACH 3005 chassis
- Separate FAN 1 and FAN 2 status indication
M-AIR2 restores the dedicated forced-air cooling path used by compatible MACH 3000 basic devices.
Its monitored dual-fan arrangement helps maintenance teams distinguish a cooling fault from a switching or communication problem.
Replacement planning should preserve the 943 678-001 identity, chassis compatibility, connector condition and unobstructed airflow path.
Availability, condition, price, and shipping time for M-AIR2 are confirmed during quotation.
