H3C LSW1FAN

The H3C LSW1FAN is a fan tray designed for use with various H3C Ethernet switches. This device features a combination of two 70 x 70 x 25.4 mm fans and four 40 x 40 x 28 mm fans, providing a total airflow capacity of 150 cubic feet per minute (CFM). This ensures effective heat dissipation for the switch's main boards, OAP board, and power supply units (PSUs). The fans operate at variable speeds, automatically adjusting to maintain optimal cooling while minimizing noise levels.

LSW1FAN Overview and Specifications

Introduction to LSW1FAN

An LSW1FAN fan tray comprises six independent fans (two big and four small fans). The two big fans

are used for heat dissipation of the main boards of the switch, and the four small fans are used for heat

dissipation of the OAP board and power supply units (PSUs).

The fan tray features hot swappable, low noise, and low power consumption, providing good heat

dissipation for the above-mentioned devices.

LSW1BFAN Introduction and Specifications

Introduction to LSW1BFAN

An LSW1BFAN fan tray exhausts the air from the device making use of the rotation of the turbine,

providing more powerful airflows compared to common fans, and applicable to high-density devices.

The fan tray features small volume, fast heat dissipation, and hot swappable, providing powerful heat

dissipation for the above-mentioned devices.

Fan Tray Fail LEDs

The two models of fan trays do not have status LEDs. 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.

Seven-segment LED Unit

The LED displays F for fan failure.

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.

2 Removing/Installing a Fan Tray

z The LSW1FAN and LSW1BFAN fan trays are hot swappable, and therefore can be replaced with

the device running.

z 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

z Phillips screwdrivers

z ESD-preventive wrist strap

The installation tools are not provided with the Ethernet switches in this manual.

Removing a fan tray

1) Put on an ESD-preventive wrist strap, make sure that the wrist strap has a good skin contact and is

well grounded.

2) 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.

2-2

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.

Figure 2-4 Remove an LSW1BFAN (2)

After removing a fan tray, place it in an antistatic bag.

Installing a fan tray

1) Put on an ESD-preventive wrist strap, make sure that the wrist strap has a good skin contact and is

well grounded.

2) Take out the fan tray from the package, and make sure that the fan tray model matches the device

model.

3) 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

Figure 2-5 and Figure 2-6.

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.

z 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.

z If the captive screw cannot be tightly fixed, check the installation of the fan tray.

2-5

Maintaining a Fan Tray

To ensure normal operation and long service life of your fan trays, note the following when using fan

trays:

z Put on an ESD-preventive wrist strap and ensure a good skin contact.

z Adequate clearance is reserved at the air inlet/exhaust vents for ventilation.

z The rack or table/workbench has a good ventilation system.
