Checklist for Monitoring Redundant Cooling System Components on page 623
The cooling system contains the following components:
Two front fan trays
Rear fan tray
Front and rear air filter
Power supply fans
The cooling system has redundant components, which are controlled by the host
subsystem. If one of the fans fails, the host subsystem increases the speed of the
remaining fans to provide sufficient cooling for the TX Matrix Plus router indefinitely.
Figure 329 on page 642 shows airflow through the TX Matrix Plus router.
