Replacing fan assemblies in the BigIron RX-16 The BigIron RX-16 has three fan assemblies: one accessible from the front of the chassis and two accessible from the rear. The front assembly pushes air into the chassis and the rear fans pull air out. You can remove and replace a fan assembly while the BigIron RX-16 chassis is powered on and running. CAUTION To avoid overheating of the BigIron RX-16 chassis, remove only one fan assembly at a time, and replace it promptly. Do not remove all fans from the chassis at one time. To replace a fan, 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 BigIron RX Series chassis DANGER For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor. Replacing the rear fan assemblies in the BigIron RX-16 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. 2. Using the flathead screwdriver, loosen the four captive screws that secure the fan (marked "Fan A" or "Fan B") to the chassis rear. 3. Remove the fan from the chassis by inserting your fingers underneath the fan enclosure and pulling the enclosure toward you as shown in Figure 78. Pulling the enclosure unseats the fan connector from a chassis connector. DANGER Be careful not to insert your fingers into the fan while removing it from the chassis.

Replacing fan assemblies in the BigIron RX-16
The BigIron RX-16 has three fan assemblies: one accessible from the front of the chassis and two
accessible from the rear. The front assembly pushes air into the chassis and the rear fans pull air
out.
You can remove and replace a fan assembly while the BigIron RX-16 chassis is powered on and
running.
CAUTION
To avoid overheating of the BigIron RX-16 chassis, remove only one fan assembly at a time, and
replace it promptly. Do not remove all fans from the chassis at one time.
To replace a fan, 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 BigIron RX Series
chassis
DANGER
For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor.
Replacing the rear fan assemblies in the BigIron RX-16
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.

Using the flathead screwdriver, loosen the four captive screws that secure the fan (marked
“Fan A” or “Fan B”) to the chassis rear.
3.
Remove the fan from the chassis by inserting your fingers underneath the fan enclosure and
pulling the enclosure toward you as shown in
Figure 78
. Pulling the enclosure unseats the fan
connector from a chassis connector.

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.
