The fan tray features small volume, fast heat dissipation, and hot swappable, providing powerful heat dissipation for the above-mentioned devices. 1-2 Figure 1-2 LSW1BFAN view (1): Captive screw (3): Fan tray handle (2): Air vent (4): Captive screw LSW1BFAN Specifications Table 1-3 LSW1BFAN specifications Specification Fan number Fan speed Max airflow Input voltage Power consumption Acoustics Operating temperature Relative humidity (noncondensing) Storage temperature Storage relative humidity (noncondensing) 1 5000 R.

You can check the system status LED and the seven-segment LED of the device installed with a fan tray to determine whether the fan tray operates normally. If the fan tray fails, the two LEDs give an indication, as shown in Table 1-4. 1-3 Table 1-4 Fan tray fail LEDs description LED System status LED SYS Mark Steady red The LED displays F for fan failure. Seven-segment LED Unit State Only when the system status LED and the seven-segment LED are displayed as steady red and F respectively does it indicate that a fan tray fails. 1-4 2 Removing/Installing a Fan Tray The LSW1FAN and LSW1BFAN fan trays are hot swappable, and therefore can be replaced with the device running. The two models of fan trays and the devices are installed when shipped. This chapter mainly introduces how to replace a fan tray when it fails. The fan trays are hot swappable, and can be replaced with the device running. However, to prevent overheating, do not operate the system without the fan trays for more than 2 minutes. Preparing Tools Phillips screwdrivers ESD-preventive wrist strap The installation tools are not provided with the Ethernet switches in this manual. Removing a fan tray 1) 2) Put on an ESD-preventive wrist strap, make sure that the wrist strap has a good skin contact and is well grounded. Loosen the screw on the fan tray with a Phillips screwdriver until the screw is completely separated from the device, as shown in Figure 2-1 and Figure 2-2. 2-1 Figure 2-1 Remove an LSW1FAN (1) Figure 2-2 Remove an LSW1BFAN (1) 3) Holding the handle of the fan tray with one hand, pull part of the fan tray out. Then supporting the bottom of the fan tray with the other hand, pull it straight out of the fan tray slot along the guide rails, as shown in Figure 2-3 and Figure 2-4. To replace a fan tray with the device running, pull out the fan tray after it stop rotating. Keep your hands away from the spinning fan blades even if the fan stops rotating; otherwise, the dynamic balance may be broken, and thus the fan noise will be increased. 2-2 Figure 2-3 Remove an LSW1FAN (2) Figure 2-4 Remove an LSW1BFAN (2) After removing a fan tray, place it in an antistatic bag. Installing a fan tray 1) 2) 3) Put on an ESD-preventive wrist strap, make sure that the wrist strap has a good skin contact and is well grounded. Take out the fan tray from the package, and make sure that the fan tray model matches the device model. Holding the handle of the fan tray with one hand and its bottom with the other hand, gently insert the fan tray into the fan tray slot until the fan tray connector well touches the backplane, as shown in Figure 2-5 and Figure 2-6. Figure 2-5 Install an LSW1FAN (1) 2-3 Figure 2-6 Install an LSW1BFAN (1) 4) Fasten the screws with a Phillips screwdriver until the fan tray is well seated in the chassis, as shown in Figure 2-7 and Figure 2-8. Figure 2-7 Install an LSW1FAN (2) Figure 2-8 Install an LSW1BFAN (2) To avoid damaging the connectors on a fan tray and backplane, slowly insert the fan tray. If you feel hard when inserting the fan tray, plug out the fan tray and insert it again. If the captive screw cannot be tightly fixed, check the installation of the fan tray. 2-4 Maintaining a Fan Tray To ensure normal operation and long service life of your fan trays, note the following when using fan trays: Put on an ESD-preventive wrist strap and ensure a good skin contact.
