NOTE
If you did not remove the extra shipment screws from the BigIron RX-4 and BigIron RX-8 chassis
during installation (refer to
“Removing BigIron RX-4 extra shipment screws” on page 30), then you
will not be able to remove the fan tray assembly. In this case, you will have to remove the BigIron
RX-4 or BigIron RX-8 from the rack to remove the shipment screws.
You can remove and replace a fan assembly while the BigIron RX-4 and BigIron RX-8 chassis are
powered on and running.
To replace a fan, you need the following:
•
A new fan assembly, which you can order from Brocade
•
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.
Follow the steps given below to replace a fan assembly in the BigIron RX-4 and BigIron RX-8.
1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector
located in the upper right corner of the chassis rear.
2. Push down on the latch release with your thumb.
3. Remove the fan assembly from the chassis by grabbing the handle on the fan assembly and
pulling it toward you as shown in Figure 80 and Figure 81 . Pulling the enclosure unseats the
fan assembly connector from a chassis connector.
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.
