Installing and removing a fan tray
The installation and removal procedures for the LSWM1HFANSC and LSWM1HFANSCB are similar.
Safety guidelines
To avoid fan tray and device damage and bodily injury, follow these guidelines when you install or
remove a fan tray:
•Wear an ESD-preventive wrist strap, and make sure the wrist strap makes good skin contact
and is properly grounded.
•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
•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.
To install a fan tray:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is properly
grounded.
2. Unpack the fan tray and verify 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).

CAUTION:
•To prevent damage to the fan tray or the connector on the backplane, insert the fan tray gently. I
f
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 you replace a fan tray with the device running, pay attention to safety with electricity.
•Do not touch rotating fans when replacing a fan tray with the device running. To remove the fan
tray, wait until the fans stop rotating.
•Do not touch the fans even if they stop rotating. Otherwise, you might break the dynamic balance
of the fans, resulting in greater operation noise.
•After you remove a fan tray with the device running, install a new fan tray within two minutes to
ensure proper ventilation of the device.
To remove a fan tray:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is properly
grounded.
2. Face the fan tray to be removed from the device. Loosen the captivescrews on the fan tray with
a Philips screwdriver until the captive screws fall off the device, as shown in callout 1 in Figure
4.
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 anti-static bag.
