NOTE
If you want to perform a hitless upgrade, replace one power supply unit at a time, and make sure the device has at least +1
redundancy at all times.
CAUTION
Remove the power cord from a power supply before you install it in or remove it from the device. Otherwise, the power supply
or the device could be damaged as a result. (The device can be running while a power supply is being installed or removed, but
the power supply itself should not be connected to a power source.)
NOTE
In the 32-slot router, you cannot unlatch and remove a power supply without first releasing the cord retainer and removing the
power cord.
Rack mounting brackets
All routers ship with pre-installed mounting brackets that allow you to front-mount the router in a standard 19-inch (EIA310-D) rack. For
instructions about how to mount the router in a rack, refer to the installation chapter that is appropriate for your router model.
You can also mid-mount your 4-, 8- or 16-slot router in a rack using the brackets that ship with the router. You simply remove the
brackets from the front of the router and mount them midway along the sides of the router. For more information, see the installation
chapter appropriated for your router model.
Brocade MLXe Series routers can also be mounted in a EIA rack or 4-post rack using optional rack mount kits available from Brocade.
For information about how to install your Brocade MLXe Series router in a EIA rack or 4-post rack, refer to EIA rack or 4-Post Rack
Mount Kit contents on page 119.

16-slot router: Equipped with two high-speed fan assemblies. Each fan assembly contains two 4-speed fans with four fan
controllers to support redundancy. High-speed fans are identified in the show chassis command output in the following
manner:
Rev A Back Fan A-1: Status = OK, Speed = LOW (50%)
Rev A Back Fan A-2: Status = OK, Speed = LOW (50%)
32-slot router: Equipped with ten fan assemblies. Each fan assembly contains a 4-speed fan. The fan trays support four
settings, 50%, 60%, 75%, and 100%, as the normal fan speeds, which are set by the management module.
You can install an optional upward air deflector on the fans of 32-slot routers using a fan deflector kit from Brocade.
The following figures show the fan locations for 4- 8-, 16-, and 32-slot routers.
