Installing upward deflectors on fan assemblies
Before beginning this procedure, verify that you have the correct number of upward deflectors (part
number 80-1004745-01). You can install up to eight deflectors on each router. You can remove
each fan assembly while the router is running; however, you must not remove more than one fan
assembly at any time to prevent the router from overheating.
If the router is not receiving power, you can remove more than one fan assembly at a time.
It will take about one hour to complete this procedure for each Brocade MLXe-32 router.
The following items are required for this procedure:
• Phillips screwdriver
• Small flathead screwdriver
• ESD wrist strap
For safety reasons, the ESD wrist strap should contain a 1 megohm series resistor.
