The fans have high speed modes. By default, the fans start at high speed. Speed is gradually
reduced to fit environmental temperature during the first 30 minutes of operation.
The MCU raises fan speed when:
•It senses high temperatures within the chassis.
•One or more fans fail.
•One of the fan drawer is removed.
The MCU returns fan speed to normal (low) when:
•Temperatures within the chassis falls to acceptable levels.
•A missing fan drawer is returned to the chassis.

Cleaning or Replacing the MCU Air Filter
The air filter is located in the fan drawer chassis airflow intake, at the right side of the right fan
drawer.
You must periodically clean or replace the air filter. Once a month (or more often in dusty
environments), examine the filter and clean or replace it if it is dirty:
•Keep a log of the date of each filter cleaning and filter replacement.
•You can clean or replace the filters while the MCU is powered on and fully operational.
Caution You can replace the air filter without powering off the MCU only if you are able to do it within five
minutes. Otherwise, we recommend that you power off the MCU before replacing the air filter.
Before You Begin
Make sure you have the following equipment:
•A grounding strap
•A No. 2 Phillips screwdriver
•Filter cleaning resources: vacuum cleaner, plain water, or hot water and milder detergent (if
the filter is very dirty).
•A replacement filter, if necessary. Contact customer support to order a new air filter.
Procedure
Step 1 Connect the grounding strap to the electrostatic discharge (ESD) point on the rack.
Step 2 Using the Phillips-head screwdriver, unscrew the screw that secure the filter drawer panel to the
right fan drawer panel (Figure 1-5 on page 8) and slide the filter drawer out of the chassis
(Figure 1-6 on page 9).

Figure 1-6 Removing the fan drawer from the chassis
Step 3 If you decide to clean the filter, use one of these cleaning methods:
•Vacuum cleaner (preferred). You do not need to dry the filter afterwards. Vacuum the filter
until it is clean and free of dust.
•Plain water. Hold the filter under the water with the metal grid facing toward you and let
the water flow down through the filter. This orientation causes the water to flow through
the filter, in the direction opposite to the usual air flow, so you dislodge rather than embed
matter trapped in the filter. Allow the filter to dry thoroughly before reinstalling it.
•Hot water and mild detergent. if the filter is too dirty to be completely cleaned with a
vacuum or with plain water, immerse the filter in a solution of hot water and mild
detergent. Rinse the filter thoroughly in plain water and allow it to dry completely before
reinstalling it.
Step 4 Replace the cleaned filter or install the replacement filter by sliding it into its slot near the right
fan tray.
Step 5 Use the Phillips-head screwdriver to tighten the screw and secure the fan drawer panel to the
right fan tray panel.
