Cooling system and fans

The fans cool the CPU, main memory, and voltage regulators. For the PowerConnect B-FCX624s

and PowerConnect B-FCX648s switches, the fans use either a push or pull configuration to move

the air from the right side of the device to the left side of the device.

•Total cooling capacity: 80 to 130 watts

•Total air flow: 34.3 CFM

•Operating noise: ideal 51 dB-A

For the PowerConnect B-FCX624E and PowerConnect B-FCX648E models, the air flows from the

front to the back (FtB) of the device. For the PowerConnect B-FCX624I and PowerConnect

B-FCX648I models, the air flows from the back to the front (BtF) of the device.

•Total cooling capacity: 180 Watts

•Total air flow: 85.2 CFM

•Operating noise: ideal 60 dB-A

NOTE

Operating noise is based on the ISO 7779 standard.

Figure 39 shows the airflow for the PowerConnect B-FCX624s and PowerConnect B-FCX648s

models. Figure 40 shows airflow for PowerConnect B-FCX624-E and PowerConnect B-FCX648-E

devices and Figure 41 shows airflow for PowerConnect B-FCX624-I and PowerConnect B-FCX648-I

devices.

CAUTION

For the PowerConnect B-FCX624E, PowerConnect B-FCX624I, PowerConnect B-FCX648E, and

PowerConnect B-FCX648I devices, be sure that the airflow direction of the power supply unit

matches that of the installed fan tray. The power supplies and fan trays are clearly labeled with

either a green arrow with an “E”, or an orange arrow with an “I” as shown in Table 1 on page 3.

For an illustration of the fan tray labels, see “Power supply and fan tray labels for PowerConnect

B-FCX624-E, PowerConnect B-FCX624-I, PowerConnect B-FCX648-E, and PowerConnect

B-FCX648-I devices” on page 3.
