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-head screwdriver through the handle on the blank
panel and pull out the blank panel gently. See callout 2 in
Figure
3 .
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 .
