Installing and replacing a fan tray

IMPORTANT:

Before you install a fan tray,

• Make sure the air flow direction of the fan tray is as required.

• Make sure you install two fan trays of the same model for the

switch.

The installation and removal procedures for the back-to-front airflow fan

tray and front-to-back airflow fan tray are similar.

Installing a fan tray

1. Wear an ESD wrist strap, and make sure it makes good skin

contact and is correctly grounded.

2. Use a Phillips screwdriver to loosen the captive screws on the

blank panel of the fan tray slot. See callout 1 in Figure 3.

3. Thread a flat-hea

d screwdriver through the handle on the blank

panel and pull out the blank panel gently. See callout 2 in Figure

Keep the

removed blank panel for future use.

4. Unpack the fan tray.

5. Holding the fan tray with both hands with the upside (marked with

a "TOP" sign) up, gently push the fan tray into the slot along the

guide rails until the fan tray completely seats into the slot. See

callout 3 in Figure 3.
