fails. For power redundancy, you must purchase additional power supplies depending on how you populate your router. For

determining the number of power supplies required for redundancy, refer to Chapter 7, "Hardware Specifications".

NOTE

1800W AC power supplies support low and high line operation. For line voltages between 90 - 180, the power supply

operates at 1200W. For line voltages between 180 - 264, the power supply operates at 1800W.

32-slot router: Supports 2100W AC, 2400W AC and DC, and 3000W AC and DC models. Accommodates eight power

supplies. Because power is supplied over a common power bus, any power supply installed in addition to the minimum

required provides backup for any power supply that fails. For power redundancy, you must purchase additional power supplies

depending on how you populate your router. For determining the number of power supplies required for redundancy, refer to

Chapter 7, "Hardware Specifications".

Power supply interoperability

For Brocade MLXe Series routers, power supplies for the 4-slot, 8-slot, and 16-slot devices are interchangeable. Power supplies for the

Brocade MLXe Series 32-slot devices cannot be used in Brocade MLXe Series 4-slot, 8-slot, or 16-slot devices.

For power supply specifications, refer to

Power supplies are installed in slots along the bottom of 8-slot, 16-slot, and 32-slot routers. Power supplies are installed in slots in the

rear of 4-slot routers.

Power supplies provide power to all router components, share the workload equally, and report status to the management module. If the

management module detects that a power supply has failed or overheated, the management module redistributes the workload of the

failed power supply to the remaining power supplies.

Power supplies generally have three LEDs on the faceplate that provide status for input power, output power, and notification of alarms. If

the input power and output power LEDs are on (steady green), the power supply is providing power to the router components. For more

information about power supply LEDs, refer to the AC and DC power supply sections in

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.

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.
