Installing and removing a fan tray

The installation and removal procedures for the LSWM1FANSC and LSWM1FANSCB are similar.

For more information, see “Installing a fan tray” and “Removing a fan tray.”

Safety guidelines

To avoid fan tray and device damage, and bodily injury, note the following guidelines when installing

or removing a fan tray:

•Wear an ESD-preventive wrist strap, and make sure the wrist strap makes good skin contact.

•Do not touch any wire or connector on a fan tray.

•Do not place a fan tray on a moist area, and avoid liquid flowing into the fan tray.

•Do not remove any component on a fan tray. If a failure occurs on the internal wires or units,

contact the technical stuff to troubleshoot the problem.

Tools required

Prepare the following tools when installing and removing a fan tray:

•Phillips screwdriver

•ESD-preventive wrist strap

Installing a fan tray

TIP:

Before installing a fan tray, make sure the air flow of the fan tray is as required.

1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well

grounded.

2. Take the fan tray from the package and check that the fan tray model is as required.

3. Face the slot into which the fan tray is to be installed. Grasp the handle of the fan tray with one

hand and support the fan tray bottom with the other, and then slide the fan tray along the guide

rails into the slot until the fan tray seats into the slot and has a firm contact with the connector on

the backplane (see callout 1 in Figure 3).

4. Fasten the captive screws on the fan tray with a Philips screwdriveruntil the fan tray is fixed into

the chassis (see callout 2 in Figure 3).

Figure 3 Install a fan tray

(1) Slide the fan tray into the slot (2) Fasten the captive screws

CAUTION:

•To prevent damage to the fan tray or the connector on the backplane, insert the fan tray gently. I

you encounter a hard resistance while inserting the fan tray, pull out the fan tray and then insert it

again.

•If the captive screws cannot be tightly fixed, check the installation of the fan tray.

Removing a fan tray

CAUTION:

•When replacing a fan tray with the device running, note safety with electricity.

•Do not touch rotating fans when replacing a fan tray with the device running.

1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well

grounded.

2. Face the fan tray to be removed from the device. Loosen the captive screws on the fan traywith

a Philips screwdriver until the captive screws fall off the device, as shown in callout 1 in Figure

3. Grasping the handle of the fan tray with one hand, pull the fan tray part way out the slot.

Supporting the fan tray bottom with the other hand, pull the fan tray slowly along the guide rails

out of the slot, as shown in callout 2 in Figure 4.

4. Put the removed fan tray on an anti-static mat or in its original package.

Figure 4 Remove a fan tray

(1) Loosen the captive screws on the fan tray (2) Pull the fan tray out of the slot

CAUTION:

•When removing a fan tray, take out the fan tray after the fans stop rotating.

•Do not touch the fans even if the fans stop rotating to avoid affecting the fan balance, which can

cause greater fan operation noise.

•To ensure normal operation of the device, install a new fan tray within two minutes after the fan

tray is removed if you replace a fan tray with the device running.
