Replacing cooling system components

You can remove and replace a fan assembly while the BigIron RX-32 chassis is powered on and
running.
CAUTION
To avoid overheating of the BigIron RX-32 chassis, remove only one fan assembly at a time, and
replace it promptly. Wait for the LED on the fan assembly being replaced to turn green before
replacing another fan assembly. Do not remove all fans from the chassis at one time.
Before replacing a fan assembly, you need the following:
•
A new fan assembly, which you can order from Brocade
•
A small flathead screwdriver
•
An ESD wrist strap with a plug for connection to the ESD connector on the front of the chassis.
DANGER
For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor.
Follow the steps given below to replace a fan assembly.
1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector on
the chassis.
2. Using the flathead screwdriver, remove the screws that secure the fan assembly face plate on
the rear of the chassis.
3. Remove the fan assembly from the chassis by grasping the handle on the face plate and
pulling the fan assembly toward you as shown in Figure 78 . Pulling the fan assembly unseats
the fan connector from a chassis connector.
DANGER
The BigIron RX-32 fan assembly is heavy and will be off-balance as you remove it. Use both
hands on the handle.
DANGER
Be careful not to insert your fingers into the fan while removing it from the chassis. The fan may
still be spinning at a high speed.
