Part number Description
BR-MLXE-32-DCPWR-3000 32-slot NetIron MLXe/XMR/MLX DC 3000W power supply.
NIBI-32-ACPWR-A 32-Slot NetIron MLXe/XMR/MLX AC 2400W power supply.
NIBI-32-DCPWR 32-Slot NetIron MLXe/XMR/MLX DC 2400W power supply.
Brocade MLXe Series routers support the following power supply options:
∙ 4-slot router: Can accommodate four 1200W or 1800W power supplies. 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".
∙ 8-slot router: Can accommodate up to four 1200W or 1800W AC and DC 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 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".
∙ 16-slot router: Can accommodate eight 1200W or 1800W AC and DC 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".
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 specifications on page 265.
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 Observing the LEDs on page 169.
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.
