Brocade MLX Series and Brocade NetIron XMR Hardware ...

Router modules 1• 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 tothe two required provides backup for any supply that fails. For full redundancy for the requiredpower supplies, you must add two additional power supplies.• 16-slot router: Can accommodate eight 1200W or 1800W AC and DC power supplies. Becausepower is supplied over a common power bus, any power supply installed in addition to the fourrequired provides backup for any power supply that fails. For full redundancy for the requiredpower supplies, you must add four additional power supplies.NOTE1800W 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 powersupply operates at 1800W.• 32-slot router: Supports 2100W AC, 2400W AC and DC, and 3000W AC and DC models.Accommodates eight power supplies.The following redundancy configurations apply:- If you are using 2100W AC power supplies, five are required and three are redundant(200-240 volts AC only).- If you are using 2400W AC or 2400W DC power supplies, four are required and four areredundant (200-240 volts AC only).- If you are using 2100W and 2400W power supplies (AC or DC) in combination, five arerequired and three are redundant.- If you are using 3000W AC or DC power supplies, four are required and four are redundant.Because power is supplied over a common power bus, any power supply installed in addition torequired power supplies provides backup for any power supply that fails.Power supply interoperabilityFor Brocade MLXe routers, power supplies for the 4-slot, 8-slot, and 16-slot devices areinterchangeable. Power supplies for the Brocade MLXe 32-slot devices cannot be used in BrocadeMLXe 4-slot, 8-slot, or 16-slot devices.For Brocade MLX Series and Brocade NetIron XMR 32-slot devices, you can mix 2400W and3000W power supply units.For Brocade MLX and Brocade NetIron XMR devices, only the 8-slot and 16-slot router powersupplies are interchangeable. The 4-slot and 32-slot power supplies cannot be used in 8-slot or16-slot Brocade MLX or Brocade NetIron XMR devices.For power supply specifications, refer to “Power specifications” on page 384.Power supplies are installed in slots along the bottom of 8-slot, 16-slot, and 32-slot routers. Powersupplies are installed in slots in the rear of 4-slot routers.Power supplies provide power to all router components, share the workload equally, and reportstatus to the management module. If the management module detects that a power supply hasfailed or overheated, the management module redistributes the workload of the failed powersupply 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 (steadygreen), the power supply is providing power to the router components. For more information aboutpower supply LEDs, refer to the AC and DC power supply sections in Table 39 on page 229.Brocade MLX Series and Brocade NetIron XMR Hardware Installation Guide 5153-1002373-02
