Brocade Communications Systems 53-1002373-02 manual Rack mounting brackets

1 Router modules

NOTE

After a power supply is removed from a router, the software determines if there is enough power to operate all of the interface modules. If there is not enough power, some interface modules will be powered off.

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.

DANGER

Power supplies are hot-swappable, which means they can be removed and replaced while the router is powered on and running. However, Brocade recommends that you disconnect a power supply from the power source before removing and replacing the supply. The 4-, 8-, and 16-slot router can be running while a power supply is being removed and replaced, but the power supply itself should not be connected to a power source. Otherwise, you could be injured, or the power supply or other parts of the router could be damaged. (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 routers can also be mounted in a cabinet or 4-post rack using optional rack mount kits available from Brocade. For information about how to install your Brocade MLXe router in a cabinet or 4-post rack, refer to “Cabinet or 4-Post Rack Mount Kit contents” on page 100.
