Installing and removing a fan tray
The installation and removal procedures for the LSVM1FANSC and LSVM1FANSCB 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.
•You must install two fan trays, with the same model and air flow direction, to the switch.
To install a fan tray:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2. Unpack the fan tray 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 screwdriver until the fan tray is fixed into
the chassis (see callout 2 in Figure 3).

(1) Slide the fan tray into the slot (2) Fasten the captive screws
CAUTION:
•To prevent dama
g
e to the fan tray or the connector on the backplane, insert the fan tray
g
ently. If 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.
To remove a fan tray:
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 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 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 you remove 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.
