Router modules

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 routers, power supplies for the 4-slot, 8-slot, and 16-slot devices are
interchangeable. Power supplies for the Brocade MLXe 32-slot devices cannot be used in Brocade
MLXe 4-slot, 8-slot, or 16-slot devices.
For power supply specifications, refer to “Power specifications” on page 217.
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
Table 33 on page 229.
