Operating the Core Switch 2/64
112 Core Switch 2/64 V4.1 Installation Guide
Blower Assemblies LEDs
The switch is cooled by three blower assemblies located on the blower assembly
side of the chassis. The air enters through the vents on the blower assembly side of
the chassis and exits from the vent in the top of the port side of the chassis. The
chassis requires a minimum airflow of 350 cubic feet per minute. This requires a
minimum of two blower assemblies operating at all times.
The blower assemblies are hot-swappable. If more than one blower assembly
must be removed at the same time, turn off the switch to prevent overheating.
Each blower assembly contains a power LED and a fault LED, see Figure 25 .
Table 12 is a list of blower assembly LED Patterns, and their meanings.
